Engine and parts help... mild road engine project

[Nico86]

I've planned a W110 with 1.25:1 rockers, with HD single or dual valves springs ?

[Sander/DVK]

Single springs are fine. I would use the Berg or CB ones.

[Zach Gomulka]

With the extra lift of 1.25's I suggest using duals. If your heads aren't ported, you wont be taking advantage of the extra .060" anyway. Just keep it simple, single springs and 1.1 rockers.

[Nico86]

Thanks Sander and Zach. 
Heads will have a little work done but not ported. 1.1 or 1.25 doesn't seem to change things a lot or worth machining the heads for dual springs. All dual springs need the heads to be machined ?

[Zach Gomulka]

All dual springs need the heads to be machined ?

Yes. Keep it simple, 110, single HD's, and stock rockers

[Diederick/DVK]

nico, you might wanna give the porting a go following the bill fisher book or so.
there's a lot to be gained, and a lot to be missed if you don't.

[Jon]

Dual or single springs means nothing, spring pressure does. If you can get the same pressure out of one you are fine. Using lightweight followers and/or push rods will also help the lifter get around that aggressive cam. 

[Nico86]

Thank you guys. 

This cam-rockers-ratio-lift-spring-calculating thing is giving me headache 

[Nico86]

Think I will maybe wait a few more weeks and have the big work on the heads done by someone who knows : porting, chambers and valve seats. But I will stay with stock size valves to keep it the more simple.

Then for the rockers it will be 1.1 with single springs or 1.25 if I can find matching single springs (or I'll have heads machined for duals as they will be worked)

I bought this today... 




And this...

[Nico86]

A question about the 009 distributor and blue coil.

All the new parts I've found are from Brazil. Is it good to use the brazilian-made we can find new ? Or is it better to choose german parts ? There's also an Empi 009 but I know what to do with this... 

I was possibly thinking of getting a new brazilian blue coil and ask Glenn Ring for a german 009...

[Nico86]

I'm wondering if I'll order a crank at DPR or not  It seems that having mine 8-dowelled and balanced  in France will cost more than a complete DPR one...

[volkskris]

your crank will need to get balanced with the flywheel anyway, DPR crank or not. still buying a DPR crank would be the better choice if you'd want to do an update on the engine later.

[Zach Gomulka]

I think that is a very wise decision.

[fredy66]

ore just go for a 78 when you are at  it   

[Nico86]

Yeah I could but not this time 

[Zach Gomulka]

78 would be a pain in the ass to build with A pistons. A 74 on the other hand would be quite easy... How does a 1904 sound?

[Nico86]

I bought this today... 

I received it today, and what I can say is don't buy this piece of cr** ! It's unstabilized even on a glass table, the tare is not precise and it only reads 0g, no 0,0g or 0,00g...

Someone knows where can I find a good one ? 

[j-f]

If you plan to use it to weight your pistons and rods, you don't need a more accurate reading than 1g. And to make things more simple, you can order your piston and rods already blue printed.
For your ignition, I think a good used original 009 (Jo Clifford have two for sale in the classifieds right) or a rebuild 019. Put an electronic ignition in it with a matching coil (>3Ohms primary resistance).
For the crank, a DPR is 280€ and a 4340 is 345€ from slideperformance for example. DPR are good stuff as they use a oem cranckshaft.And they are fully controlled..
A 4340 74mm is 349€ thought 
Something I would say is to buy your parts locally. If you buy parts from everywhere and then ask a local shop to help you to build your engine, I think they will just told you to ask where you buy your parts . 

[Nico86]

Thanks JF I will check that.  I tried it today with some bolts and washers and I find it very unprecise.

Well they don't really care were I get the parts from, because they usually work on Renault and Gordini's engine.

Need help for the crank mounting kit, I know I'll need this : http://www.vwparts.net/111105223.html

But about this ?
http://www.vwparts.net/113105241A.html
http://www.vwparts.net/BP4000-72.html
http://www.vwparts.net/BP4034.html

Would be great to have the list of shims/gasket/gear for mounting the crank 

[Zach Gomulka]

http://www.vwparts.net/BP4000-72.html

You don't need that. It's for a flanged crank/flywheel

[Nico86]

Ok thanks  I looked the technical guide so I need this :

http://www.vwparts.net/111105223.html + http://www.vwparts.net/113105241A.html + http://www.vwparts.net/BP4034.html + the pulley seal (or it's just for sand-seal pulley) ??

[Nico86]

A few more newbie/stupid questions 

I'm starting ordering parts, here are the last things I need help with :

1. About copperheads gaskets, do I need it ? Are they included in the 1300/1600 engine gasket kit ? I see there are 0.040" and 0.060"...

2. To mount the crank in the case I need : bearings kit of course + brass gear + oil slinger + flywheel seal + this http://www.vwparts.net/BP4034.html  No seal behind the crank pulley right ?

3. About the seals between cylinders and case (don't know the name in english) the one in the 1300/1600 engine gasket kit are ok ? Or I need other seals for the 90,5 cylinders ?

4. The correct Mahle 90,5 kit I need is the A forged piston-cyl. kit : http://www.vwparts.net/BP4576-16X.html ?

[bugnut68]

Here's a little advice from my recent experiences in engine building: they sell two different gasket kits, one of which includes the main flywheel seal.  Get this one, as it will save you the aggravation of realizing you are lacking all the needed seals to seal up your short block.  Some outfits are selling just the gasket kits without the main seal so that you have to spend more money with them... weak, IMO.  Don't forget the cam plug, too!

That's the kind of thing I don't want to happen : forget a little gasket or part in the middle of the building, then I'll have to order it and wait for days before it arrives.

Does this kit includes all the hardware I need to mount the crank :  http://shop.hoffmann-speedster.com/catalog/product_info.php?cPath=395_1732_1746&products_id=1149&language=us  ??

Up guys these are the last things I need to know, then I can start collecting parts. 

[Zach Gomulka]

Yup, that should do it. You'll need a pulley bolt, and flywheel bolt as well, of course
