Title: Steer me right folks! Post by: andy198712 on August 25, 2012, 21:58:36 pm Hello,
i've not been here long but enjoyed reading and taking it all in, also amazed to see some huge names here all helping and chipping in, including the writer of the book sat next to my bed! (Hello) anyway, the dilemma: i started out thinking i would build a warm 1641, that turned into a 1776, which grew to a 1955, which is now and finally not gonna change a 2110cc engine. so here's my spec of what i have thus far -D code engine cases, full flowed, waiting to be bored out -CB super race 82mm crank, VW journal -CB unitech HD plus rods -FK8 cam -CB straight cuts -CB bigfoot lifters (thinking of swapping to TP ones) -Bugpack drysump pump -Bugpack HD alu pushrods -Jaycee PR tubes -Bugpack 1.4 forged rockers -CB044 40x35 oval ported and unshrouded by me -Fuel injection via megasquirt same with crank triggered ignition so thats my current spec, i havnt brought the 90.5 b's yet. i also intend to coat the friction surfaces with DFL and probably do the heads and barrels with a heat dispersant coating. my question is, this is a daily, and i use it for work ect it'll be going in a 1972 beetle 1200. am i stupid to consider turboing it?! if i go NA i was going to use GSXR TBI's on adapted twin carb manifolds. if i went turbo i was going to go with cb twinport manifold ends with injectors and single TB, cb hideaway header and unsure of turbo...... any experience and input? Thanks alot! P.S its my first aircooled build, and i know some parts are a bit OTT like the dry sump, efi ect but thats the part i enjoy, going that extra mile and making it a challenge Title: Re: Steer me right folks!

I would start with a new engine case if it was me though cheers richie Title: Re: Steer me right folks!

I would start with a new engine case if it was me though cheers richie i was really keen on the whole drysump idea although it does seem a bit of a pain, with the issues it chucks up, it has knock on effects on what pulley/trigger system i can run which is more money ect and exhausts as you state..... i didnt think about the turbo header and the pump.... thats the kinda help i was after so thanks :) a new case really blows my budget out the water, in an ideal world i would love one! but budget is a big factor Title: Re: Steer me right folks! Post by: Zach Gomulka on August 26, 2012, 14:19:32 pm You haven't bought the pistons and cylinders, and you haven't cut the case yet, so clearly it's time to step up to 94's ;)
If it's a daily, I'd set it up n/a first, get it sorted, then put the turbo on when you're ready. Just my opinion. Title: Re: Steer me right folks! Post by: Nico86 on August 26, 2012, 15:27:32 pm Check this thread, you will find a lot of informations. ;)

Title: Re: Steer me right folks! Post by: andy198712 on April 23, 2013, 23:39:09 pm well, just an update, i will go turbo, will drive it NA for a little while to get fuel maps licked then add a turbo header and hair dryer to the mix :)
the big question is... what cam?!?!?!?! whats the current train of thought with regards to cams and turbos? will be EFI crank fired, and thinking charge cooled with/and/or water injection... Title: Re: Steer me right folks! Post by: Fiatdude on April 24, 2013, 13:05:31 pm I got to compare the CB dry sumps vs the bugpak and I thought the CB was a better unit -- a lot of the road race guys are using it with a 3 gallon tank with very good results

Title: Re: Steer me right folks! Post by: modnrod on April 25, 2013, 03:07:28 am I went the other way in years gone past. Rather than build a bigger cc motor, I turbo'd the small one for a bit more stick. I've also had a few turbo hotrods over the years (still have a TT Supra sitting here now).
Turbos are great fun, simple, easy, huge power, it's all good, until......... ........the roads get wet or greasy/slippery, then you'll get your mirrors sucked off by a stock Hyundai Excel, the power spinning the wheels won't stop until a whole second after you've lifted, so if the tail comes out it will KEEP coming out (envisage light throttle, slight aquaplane at 100kph, turning into a slight overboost condition in less than a second, which slowly aims the car at the centre wall, in the Freeway in peak hour traffic........). Although, these experiences with my TT To#¤ta's over the years haven't stopped me from getting another one! HAHAHA! For a daily, my opinion is that turbo 2110 would be complete shite (but then again, I always was a scaredy-cat ::)), and a responsive torquey GSXR NA 2110 would be really nice, cheap EFI, good 200HP with stock injectors, sounds great, it's all good. ;D |
