Title: porsche power!
Post by: nicolas on February 06, 2014, 20:27:01 pm
OK, so i have thought about this more then once and i have tried to post it, but i can't really put it in words.

the idea i have is to 'make' a porsche out of a beetle or in my case my fastback. i am not talking about a german look, nor am i looking at the looks of a porsche. but i am looking for it's performance and handling. think more of a guy with a beetle looking at what porsche did in the late 60's early 70's
the idea i have is to make something similar in power (not really really high) and handling (quite good for it's time) of a late 60's porsche. no fancy RS or turbo. for instance my type 3 will not be used much more on the track as i will not fit a roll cage in it and the car will always be 200 - 300 kgs heavier compared to a beetle. But i do plan on taking it back a bit more on the road, with improved handling if possible.
so without saying what i have in mind, i give you a blank canvas to project your ideas and thoughts on.


ENJOY!

you're talking about 911 power or 912 1600 90ch             
356 1600 C   55 kW/75 ch   
356 1600 SC   70 kW/95 ch   
356 Carrera 2   96 kW/130 ch

911 would be closer to a type3 i guess.  ;D

That's what I had in mind when I was tuning my old GTV. In the end I feel like it was right on par, if not slightly better than a stock 912. The powerband, hp/weight, and road holding was very similar.

I do miss driving that car! Owning it was another story though ;)

Neat idea. Making a comfortable, capable, "all weather" car with ample power, sure-footed handling in all conditions, and like-stock VW reliability. Kind of my approach with my '67.

I think, number one, you're going to need to be conservative in almost every area. As you look at ways of improving performance, also look at how that mod is going to impact reliability or the day-to-day "live-a-bility" of driving the car. And also keep in mind, even if built conservatively, the car will require regular servicing. As you put the car together, keep in mind things like accessibility, will you want to add electrical accessories at a later date, weatherproofing, and engineering things to live.
As far as the motor goes, a nice tidy 90.5 x 82 that makes an honest, cool 150hp will definitely give you the best of all worlds, even in a Type 3. And also give a similar power to weight ratio as an early 911 in E or T tune. Probably better than the 911 actually. The 2110cc with 300-306' (262-268' @ 0.050"), around .470" at valve and high-airspeed 40 x 37.5 heads and 44mm carburetors will do this with ease. Don't go hog wild on heads or you will lose that top gear mid range snap that is needed for passing on highway.

As I recently put my '67 back together after paint, I kept a "GT car" mode in mind, specifically something like a 356 Carrera GT. All this played into how I wired the car, and making sure when it comes time to service stuff, it can be done without huge undertakings. The motor tune was already modeled after the Carrera. I recently drove the car home from OC back to where I live (about 70 miles one way) in pouring rain, stop and go and highway speed traffic. Having a sure footed car, with good wipers and a motor that can slog along in 1st gear at under 10 mph for 45 minutes made the trip home much better than had I been in some over-cammed, fair-weather only, prima donna that only knows perfect conditions. All that I missed was a working heater/defroster.

Cool idea, keep us posted.

Nice idea Nicolas.  ;)

My first thought is the kind of tires you will have to use. You will have to find tires that give you the best balance between the front and rear without rubbing or having to use flares. It could looks awesome if the car was done in an IMSA way, but not the case here.
Going with adjustable shocks to be able to tune them to your desire.
Adjustable sway bar.
Urethane bushings should help as well.
The engine Jim said.
Driving lesson on a race track...  ;D
Going to my place and test all that stuff on those twisty country roads we have here. I copilot  ;D ;D

Maybe the thread should be called "The ultimate aircooled daily driver"??

Pretty much the same as I was hoping to build with my '71 super.  I was thinking maybe even a mild 150hp type 4 for the long trip cooling.  I figure make everything work pretty good, instead of a couple things really good, and a couple lousy things. 

My list of "must haves" would include,
-Good bucket seats.  Stock VW seats have the lateral support of a park bench. 
-Seat heaters in the good seats
-really good tires
-very good smooth exhaust note.

I want something just like this car.  Still Cal-look, with some Porsche vibe.  Make it handle, stop, turn, and resonantly comfy, but keep it simple.

I rekn I'm sort of on your wavelength Nicolas.

Handling wise you're talking shimmying around with a bit of body roll, a glorious sound out the back, and LOTS of wheel corrections through successive corners at less than 160kph! No mid-corner braking or you're into the trees, if you need to tighten lines you need MORE throttle and a wheel flick. Something just fast enough to feel it a bit, and handling just dangerous enough to make you concentrate!  :D Keep the tyres 165s on 5.5" rims, maybe 185/70s, no bigger or they will grip too much and you lose the "feel".

I was lucky enough many many years ago to get to drive a 1968 (I think?) 911, I think it was a 2.0L 6 NA. Just absolutely lovely, but felt a bit threatening at the same time. I can see why they sold so many, and why they became an icon.

Doing this in a Fastback is what you are trying to achieve maybe?

Post by: lawrence on February 07, 2014, 06:00:04 am
Nicolas, I like your thinking. I wanted to make my beetle more like a sports car, so I made some modifications that make it handle corners well: original 356 lemmerz wheels, modern tread 185/65/15 tires, front sway bar, level ride height. I still want to add: new torsion bars and bushings, a rear camber compensator, oil filled front shocks, front disk brakes, and maybe some small driving lights.

Jim has the right idea as well. Having little things like good wipers, a tight steering box, and functioning brakes is important for comfortable driving. I replaced my steering box recently and the car is much nicer to drive. So much that I feel the torsion bars and bushings need to be replaced because the rear end feels soggy. Have fun and let us know what ideas you have.

IRS would be mandatory.

The difference in ride quality and handling is immense. Also much more stable at speed.

Hi Nicolas,

I have been looking for a one-car-do-it all kinda thing and spent a fair bit of time looking for a old Porsche. A good one is hard to find and not to forget that the prices has gone through the roof. On top of that we have the fact that everyone else have bought a old Porsche lately. Parts are stupidly expensive as well. So instead I focused my search toward finding a good and honest 1303S and that proved a lot worse than finding a good Porsche. After two years of searching and looking on several cars I had basically given up finding a good one when I got a tip from Jon (JHU) I called the guy and a few hours later it was in my garage. I drove it to the JPM Dyno Day happening in October before I parked it for the winter and started working on it. It has Kerscher disc brakes, Kerscher coil over kit with yellow Konis and Eibach springs, really comfy OMP seats, a grippy steering wheel, a tight gear shifter and a set of tires that makes it stick to the ground like it should. It is a inspiring but yet comfortable ride. It will get some new wheels with even stickier tires this winter and a Kamei spoiler up front. I will also keep on improving the handling until it is like I want it to be. The engine will be a rather mild 1915ccm with 100+hp. The gearbox is rebuilt and it got a 0.82 4th fitted for improved cruising comfort.

Here it is:

That Porsche video is awesome!!  :o

I took a lap on the Francorchamp racetrack a while back in the passenger seat of the old VW cup car from the Close family. The car was not at his best after a 6 years hibernation and a recalcitrant gearbox, but it was a blast!

http://www.youtube.com/watch?v=FYlm39VLMp0&list=UUHX7hnH_xhRuVHBY-EYXosQ&feature=share&index=10

Engine is a type4 2.4l about 215cv, Porsche gearbox, brakes and rearend. It's a 1303. It was top dog in his time.

That is my idea as well with my -59 sleeper. The chassis was already done and finished when I bought this project and unfortunately I didn't choose to replace the swing to IRS. Maybe some day I'll do that and fit also the Mendeola front end.

Title: Re: porsche power!
Post by: nicolas on February 08, 2014, 20:45:11 pm
OK. thanks already for such a great input. i really like a lot of what is being said.
I do have some parts already sorted for this car so here is what i have so far.

engine-wise i am building a low revving 2007cc engine with an FK44, some ported 40X35 heads, a good CR of 10 and the DCNFs so i can all fit it as a type3 engine under the type3 lid. all this with a stock geared re-enforced and rebuild gearbox (alas swing axle) and it will stay this way for now. i do want to make it better at handling with a torsion bar and brace, but i am not sure what would be 'ideal' yet.
the shocks are adjustable spax and the front is being fitted with a set of dropped spindles for type3 and hopefully i will be able to fit the type3 torsion bar ai have as for now it won't fit due to the lowering.
the wheels will be the empi's with 185/70 vredesteins at the back (highly recommended for looks and performance) and at the front i have always ran 165/65's, but i always found them just a bit too small, so it has been OK, but maybe i will try a 185/60 or so tyre.
brakes have been the stock drums at the back with a set of Talbot brakes at the front, which have given me more then one headache to set up correctly, but now perform well and stop in a dime.
the interiors will stay with the original non supportive 'benchy' seats as again i want to keep the car as much as it is.
i do want to upgrade the handling quite a bit so it will be more 'predictable' and in order to do what the porsche does in the video  ;D

and for reference here is a picture of the car, but i must admit is a hundred years old (silly you take pictures, but never of your own car…)

Great looking car. Cosmetically, it's perfect.

Nicolas I was thinking this morning, I think the goal for cars like this. Let's say you get a phone call from somebody that needs you as quickly as you can get there, and they're 180 miles away or so. It's evening, let's say 9:30pm and storming rainstorm and the roads to assist your friend are not straight shot, flat super-highways.
So if you had a conventional modern car and your Porsche-esque VW Type 3, just to enjoy your unexpected trip in questionable conditions on a challenging series of roads, you'd choose your Volkswagen. Hope that makes sense.
 :)

Back  in 1983 or so, a friend of mine had an early Fastback with a 2.2 911 motor on carbs, 901 gearbox and 356C brakes with 6in Fuchs all round. Was a fabulous package and one that always sticks in my memory.

hmmm. misa like that too.  ;D

it would be something in that spirit yes. and what Jim said is also correct. it should be able to do what he described. and like kalle also said it maybe one car does all. the thing is that i only drove my car about a 1000kms last year. so that is nothing really. But i do miss driving it and it is on a yearly MOT, so it could and should be a daily driver (again). my concern is however the handling aspect.
i am currently looking at getting a different set of wheels for the front, but i don't want to deviate too much from the look it has now.

Consider an engine from the last of the air cooled Porsches.
Mild 3.6 at 300 hp/260 torque with the 915 trans would be reliable, require little service and should last 100,000+ miles.

i must admit that ii have been looking at those engines, but my aim is a bit more 'conventional' and in a cal look tradition, if that means anything. so it's more 60's and 70's, the base of this car is made and is a type3 4.12 transmission (reinforced) and the engine is type1.
but this said i do like what direction you want to take this. MORE porsche power.  ;D

The CarError Fastback appears to have lived it’s first 30+ years in the arid Arizona sunshine — which left it rust-free, but worn to the core of it’s 3rd or 4th replacement engine — after 100’s of thousands of hot and hairy highway miles in the blazing Arizona heat. Many signs of it’s decades-long battle with the sun were still apparent:  The windows were blacked out. The interior was white vinyl. And an 12 Volt DC oscillating fan was mounted to a dashboard that showed more cracks than the cylinder heads around the sunken exhaust valves… But the Dusty Little wasn’t ready to give it up to the crusher.
Our intrepid Team Leader ( a friend and pit crew member of the NorCal-based, LeMons veteran ‘Super Chicken Plymouth Belvedere’) saw the Fastback sitting outside the fence of the Foreign Aid Junkyard outside Phoenix Arizona , while on a bicycle racing team spring training camp training ride near Phoenix. It’s svelte silhouette and skinnier pricetag — screamed ‘LeMons Fodder’ to a man who had just recently been baptized in the LeMon’s juice.

A deal was struck. A U-Haul car-caddy was attached to the back of the Bike Team van. The Fasty was headed for the rustier climes of the midwest. And a date with Destiny. (No wait.That was the stripper we met on the way through St. Louis)


Title: Re: porsche power!
Post by: Jim Ratto on March 17, 2014, 20:39:52 pm
Nicolas, this post really got me going and thinking and not sleeping at night.
I started weighing some pro's and con's and answering some of my own questions, regarding my car, how I best enjoy it and what makes sense going forward.
Anyway, some of you whom I've know for a long time probably have read my reminiscing over long trips to Southern CA and all over the map during the early 1990's, all done with "Version 1.0" of my car with a stroked motor. In the 24 years since, and all the cams and heads, and "try this", "try that" and time slips, it is all very obvious, none of the high-winding prima-donna stuff was nearly as much fun as the rock-solid simplicity and reliability and mid range pull that the "father" to all these other engines had. Running .560" @ the valve doesn't make a bunch of sense to me, when sitting in stop and go on 5 Freeway. Or when hidden amongst douglas firs, forgetting 9 to 5 rat slaughter we call "daily life." A 1300rpm idle probably isn't as consequential . Having to refresh springs as often as cleaning gutters out is hopeless.
So, what will this be... version 12.0? A real driver. Emphasis on real.


Title: Re: porsche power!
Post by: nicolas on March 18, 2014, 10:25:14 am
allright! maybe this could become a 'in da works tread' but hopefully in a combined way, where all our efforts and experiences can come together.

as said earlier i did have a great 2276 engine, but it wasn't a drag race car or super fast engine. pulls really well and i can get in and drive for hours. it is a bit harder on the senses then the previous 1776 i had. you have to 'work' more when driving. all good fun though.

but i want a type3 setup and the specs stated above are thought up with the idea of a medium displacement and maybe modest HP, but hopefully with a good driving-fun factor. like the post suggest, in a porsche 2.0 - 2.2l kind of way.

also, more and more, i am convinced that i and maybe a lot of us will never see the limits capable of such an engine (yes the modest one). mainly two reasons for this: 1. the driver (we are not discussing my skills or the lack of them in  this tread  ;D) 2.the handling and total setup of the car.

in my case i can say the car has been set up with 30mm torsion bars and spax adjustable shocks and it has hold up good on drag races. but in turns it loads the torsion bars so much that i have been thrown out of it more then once. it is me i know, but i was to handle easier to control with the stock torsion bars.

on the other hand i have been using talbot horizon brakes for years now and those were a very good improvement. i read about them in one of Keiths books and while on a hunt for alfa carbs in the south of France 10 years ago, i found them had them rebuild and fitted with the CSP larger diameter cylinder and correctly machined, original type 3 brakes in the back, all adjusted properly (that took me a while, because of failing aftermarkt drum brake cylinders). but i can recommend this on a type3 and probably on a beetle as well.

also another reason i wanted to get deeper into this was when i got my beetle (my first one) more than a year ago, it had mostly stock suspension setup, but drove like a cart. and more then one spirited drive in Fabs car showed me what pretty much stock beetle setups can do over my heavier type3. so Fiatdude i did understand what you posted, it is actually quite true.  ;)

My first ACVW (of my own, not my uncle's/nanna's/Opa's, etc) was a 1973 Squareback in unlovely "Baby-Poo Brown". When I bought it the Odo showed 65000km from new, and it had a tired engine (in the tropics). It was also just turned 10 years old.......(OOPS!!! Now I've given the game away a bit!)

Hahaha! Anyway, a work mate friend of mine with VW experience and I went to town on it just a tiny bit. I had sold a 12sec V8 ute to buy this wagon as my first child was on her way and I needed a family car for the little one, but who said it had to be slow?
We did all the work ourselves, and it used lots of locally available parts from other cars (mainly our local Holden), and a mates machine shop, so the cost was negligible.
The motor at least, went like this..........
* offset ground crank for 75mm Stroke (might have been 74 perhaps? A while ago now!) with 5.23" rods.
* 3.375" pistons with the tops shaved for compression height a bit and to fit, so 85.75mm bore I guess.
* hand-ported 38x33 heads (valves/springs/retainers, etc from Holden also), LOTS and LOTS of time spent here, but still fairly small volume from memory.
* Little tiny baby Norris 329S cam, love that cam, with high-ratio rockers, can't remember 1.25 or 1.4? This friend of mine (from the US) got a mate in the States to buy it and post it out.........I've been buying direct ever since!
* custom exhaust in 1.5" and a glass-pack out the side (it was the early 80s, remember?  :D)
* a single sidedraught 45 or 40 Dellorto off a Fiat/Alfa something sitting flat on top, set up in an "isolated runner" type way (I had one left in the shed, after fitting the first one to my Honda CB 750 bike..........but that's another story).

All simple stuff, easy to do. I didn't have any problems with exploding Type 3 fans because nobody told me, or the fan, it was dangerous I guess. Same for the 4-dowelled non-counterweight crank too, but good balancing saved the day I spose (either that, or I wasn't trying hard enough!).

That Squareback ran deep into the 15s and even snuck a high 14 once or twice, but for the first 100m was still just dynamite. It turned the 165s around fast sweeping corners with a hefty stomp to help steer it, and spun really cleanly to 6000.
It looked completely standard.  8)

Might do the job perhaps, or something similar?

To me, a Porsche is more about the handling. Luckily, something like this is an easy swap for your fastback.
http://www.thesamba.com/vw/classifieds/detail.php?id=1596061
As long as the motor is eager, revs very freely, and has a solid mid-range, that's mostly what you need.

Many years ago I went on a day long drive with a friend in his '85 911 to the eastern mountains of Arizona. The car had quite a few miles on it by that time, but it was meticulously maintained and didn't show it's age. What I remember mostly is how the car wasn't blisteringly fast, it may not have been the best handling car (in today's terms) but the entire package, the engine, transmission, suspension, etc. was balanced so incredibly well together that it made for a massively entertaining car to drive. The engine loved to sing at over 4,000rpm, and you could just hold it there, seemingly forever. I'll never forget that drive.

A bump to this thread as I'm looking at something like this too and since I'm selling my '64 beetle i'm looking for a new project. I might have found a nice 56 oval ragtop which I can drive for 2 years as is and in the meantime start saving and gathering parts. The engine won't be the problem there are enough options but what about the transmission? Porsche 915 gearbox? Is that possible in a oval window beetle? Changing to IRS?

:D Keep the tyres 165s on 5.5" rims, maybe 185/70s, no bigger or they will grip too much and you lose the "feel".


I feel like I have heard this advice on this board before, is that a common onion? Currently I have 145s up front and 205/65R15s in the rear on 4.5 and 5.5" 5 lug sprint stars and I feel the car under steers. I am thinking about going to 165R15s in the rear to let it loosen up a bit and see if the "feel" returns.

Does that seem like a move in the right direction?

between 205's and 165's there is a big step. maybe the 185/70 tyre is a good size. i like it, but having said this my new combo has a 195/65 tyre in the back and 175/65 in front. also i wanted the 'gap' between the skinny front and large back wheels closer to one another.

Hi Nicolas,

Do you use a narrowed front beam with your 175/65/15 tires? I've considered changing my tires from 145/15 and 165/15 to something a bit more beefy. I really like the 175/65 and 195/65 combo.  ;)

Good point and I hear what you are saying.
Unfortunately around here they 185/70s are quite hard to come by and pricy as they were only used on Porsche 928 / 944 / 964 / 968 (F). Pirelli makes a 185/70 but they are $200 a piece compared to 165s at $60 a piece.

If I give them a try I will be sure to post back with my results.

I stopped by Wedge today and saw a car with those tires. Not bad looking at all. Going down from 205's will sure take some getting used to though, at least visually.

i am not sure if i can fit them with a standard beam and dropped spindles. but i don't think it needs much if you don't lower it too much.
on the type3 it clears without issues  ;D

OK so the engine is running and so far only one quick 2km run has been made, but it all seems to work nicely so far and from what i have been gathering in this first impression, this engine might come close to what i wanted in terms of 'porsche power'

the engine is a type3

78x90.5
engle FK44 on 1.25's
CR 9.8
043 heads with 40x35 valves reworked by steve for my old 1776 and now with the chamber volume matched to the 2007cc, matched inlet manifolds
stock reworked and clearanced rods
rebushed lifterbores, clearanced
lightened flywheel (light!)
no straight cut gears
42DCNFs on berg type3 manifolds
central pivot low CSP linkage
009 with a red coil
turbo thomas 1 5/8" type3 stainless exhaust
an old 3 finger type clutch from the 70's, re-enforced(can't remember what brand it was)

well that is about it. nothing too exotic there, but it seems to make up a package that has quite a good push in the lower RPMs and since i must limit it to 5500 - 6000 rpms because of the type 3 fan, i have the whole power band put to use.
i also went for larger tyres which are now 195 back and 185 front, that seem to grip better as to what i had before (they are new as well)

i just checked my valves yesterday and hopefully the weather will improve a bit so i can get it out again, do MOT and drive in 2015!

Title: Re: porsche power!
Post by: nicolas on February 22, 2015, 12:26:25 pm
hey, maybe a bit long due for a update and no pictures yet, but i am driving the car a bit more these days!

so it feels really good, if i have to compare the 1776 and this 2007 in power, this is a step up, but not a compromise. it will cruise in 4th and pull from idle right away. i will however have to limit the rpms by means of a rev limiter of some sort as it goes fast through the rev range. it has the new tires on it (185/65/15 front and a close shave with 195/65 back), but it all fits and feels good. i have had some info on these tires and i could have gone for a 'less expensive' tire for a smaller car and not have the same top speed rating, but a lower tread wear number and have an even stickier tire. but these are really hooky and handle very well, much better as the 165's and 185's before.
the oilpressure is a bit high, but that is because the weather is still cold and the oil is too thick like Bruce suggested, i will try a 10-40w oil next time.
so far no fan is needed on the cooler and i only did small trips. if it all comes together it will be the Ninove show as it's 'new first' outing.
the only small things i want to do is get the front a bit higher to level the car better as it is still a bit low and with the bigger tires the wheel sits too deep. i tried fitting dropped spindles, but in the end it didn't work out because my brakes couldn't fit with the relocated bracket… it would have been great as the drop of these is spot on to what i want. so on the agenda is still to get that sorted.
the gearbox is reenforced type3 and seems to be holding on really good. the only other part that needs following up is the clutch. with a stage two and a stock rigid plate, i think i am on the edge of the holding power of this setup. but it works! so no changes if it works. the pedal is so smooth and soft though, easy grandpa style  ;D
i would like to know how much power it has and what it really performs at what RPMs, but no dyno run is planned, just cruise and enjoy it.

Maybe you can try an app on your smartphone that will give you 0-100km and 1/4mile e.t. . It can roughly estimate how fast (or slow  ;D )your car actually is. Car performer seems to work well.

tempted, me? nah why do you think that  ::)

BTW it is really different here (i moved three years ago now) seems like more then a few people have a heavy foot around here, the road isn't anything special or spectacular, but in this area i hear quite a few high revving cars every other day it seems…


anyway, i will fiddle with this as soon as the damn thing is fixed. broke/killed it last week.

Post by: nicolas on June 14, 2015, 06:53:45 am
another update as i have had a few issues and a bit more driving has been done now. getting ready for EBI is the main goal now and of course DRIVING!

like i said in earlier posts the clutch was soft, but it slipped. so when i started to drive it to some cars and coffee style meetings 10-15 miles around my house on a few occasions and a couple of times to work, i noticed that the clutch didn't hold up. so i ordered a daikin disc from RJvolksparts and fitted this instead. there was also some oild from teh gearbox in the housing, so i replaced the seal and took the time to install a new trowout bearing as well, something i didn't do the firts time and which i should have done the first time.
i did shim the clutch and this was on my setup a mistake so i had to take it all out again and do it over, no shims this time.
the problem is with my engine that you need to take of the complete exhaust and some oil lines as well as the whole bracing. so it is a couple of evenings work, but it seems to be done now.
i also took the time to change the oil to a semi synthetic 10w-40 and redo the oil filler tube of the type3 as it had a a hairpin hole in it when i did it the first time. so whith this down and the exhaust cementeted back in place it was time to test it again.
again, it runs great  ;D and the clutch seems to hold up. when the engine is hot the oilpressure stays at 3 bars when driving and 1 on idle (which is 800rpms). that seems low, but my experience with 3 other engines is that on my VDO's this reading is OK and there is enough pressure to lube all parts.
i want to update the iginition with an MSD to have rev limiter at 6000 or 6200 rpms max. and maybe a better spark.

and with the engine out i didn't have the exhaust hanging from under the apron. that was way better. i had to fit a big turbo muffler as it was the only thing that fits the header that i have and it isn't the best looking thing. i was pleased with my hideaway setup i have had for years, but now i am thinking about a type 3 exhaust from CSP… it might 'clean up' the rear vieuw and bring it even a bit closer to that porsche look i have been after.  ;D

I was going to redo my 2332 with a smallish cam. The heads will still remain large, so I reckon the rpm's will be limited to under 6500, but it'll still pull hard up to that as a result of moderate compression, static approx 9.8 to 1. Gone are the days of high lifts and durations, been there done that and got bored with it, smallish cams with a little engine management seems the way forward.

Looking at production cars these days, and what has happened in the last 10 years highlights this. It's normal for a 2.0 n/a motor to make  a smooth 170hp, deliver 35++ mpg and not worry about high temps.

But those are multi-valve engines with very light springs. Direct injection and 11:1+ CR too. And boring powerbands.

And LS motors, and Hemi Sixes, and Ford Cleveland V8s..........although the Clevo's are 4 times the weight, 3 times the size, 2 times the HP, and half the economy!  :D
If you going to run larger "good" heads with a smaller cam, try to open up the LSA a bit too. Most LS motors run 114, and the old 4Vs used to run 112.

hahahaha.

i always thought a fastback was a bit of a porsche…  but this is even better. it IS a porsche. cool. and flares… i am looking at quite a bit olf BMW's and the 2002's with flares are the icing on the cake. but a type3 would be great!

i just came home from a drive with the fastback as a matter of fact. haven't taken the car out in more then a month, but i had to pick up my daughter and i took the fastback.
i still have some fiddling to do to get it all working crispy clean again, and i still need to get the LM-1 fitted. the MSD is still playing tricks, so it is just a regular compufire and coil now again. but this car runs great! i think i have achieved what i wanted it to be (porsche power like-wise).
so what can i say, i need to do a bit of work on the car and hopefully i'll be able to fit the LM-1 and make some progress. i do have a good baseline now and i will keep you posted what mods will be done, what upgrades (if they really are upgrades) will be done and hopefully enjoy the car as planned this year.

looks like there are no winters anymore, so no salt on the roads and just keep on driving  ;D


oh, and as nice and tempting as this is, i will not join FB, i'll chose my own charity!

It would have been cool if it was a GT2 but it isnt. It is a "ordinary" 996 turbo.

More pictures for those not on Facebook: http://www.carfinder.pl/galeria/vw_typ3___porsche_turbo_996#category The job is being done in Poland at a shop where quite a few guys here in Norway have delievered their cars for some TLC. It looks like they know what they are doing that is for sure.

last year at DDD i had quite an issue with a campulley coming lose and the fan that rubbed the housing too much, so that was junk as well.

i was quite confident this would be a easy and straightforward rebuilt, but it ended up a bit longer as expected. parts only coming in after the vacation i have, things needing more time to do, plans changed,…
so in the end the rebuilt took the better part of 8 months, but things were ready for EBI and i got to drive it there. now a few months later i have been driving my car a lot more than last year and it feels better and better.
what have i done to it. i did in the end swap the 1.25's for 1.4's, put in new pushrods, lifters and new bearings, sealings. and i went with straight cut timing gears as i had them.

so the package i had before was allready exceding my expectations, but this is better. the engine responds more 'openend up' with the 1.4 rockers. yes i have lost a bit of bottom end power, but apart from that the engine is much more responsive and dare i say fun  ;D

so in a way it isn't the best as i want to limit it to 6000 rpms (this goes beyond 6000 easily  ::) ), but the way it makes power is an improvement. more fluid and fun. so i am very happy with it.

i hope to put more time in the car to have it tuned even better, the eternal quest for better i guess.  ;)
