Building a S2 mk2 golf

[Fat Audi 80]

That manifold is a lovely piece of work....

[s2 rich]

i agree that manifold is lush i dont suppose you would like to make me one would you lol keep up the good work cant wait till this is finished

[Jay]

good work, wish I had the time

Correct me if I am wrong but you dont appear to have a waste gate port on the manifold?? I see you have a Tial but were are you fitting it???

Thats my problem i need to tap into the manifold causing as little flow disturbance as possible. Most people jusy tap into the manifold like a t peice apparently this is bad practice because causes a disturbance right next to the turbine inlet. Im also going to start making them for my friends fiat turbo and he`s selling them on a forum. Maybe if enough people were intrested on here i could make a few for people on here

I think you may have to compromise on that with the amount of space you have to play with, unless you can taper it off the collector nicely maybe?

Just a thought, Maybe mounting the wastegate on the bottom would help ?

[Jay]

I agree with you gnutz2 the best I have seen on race engines has the waste gate feed pipe mounted so the exhaust gasses dont have to change direction, on most manifolds the port comes off at 90 degrees at best and gives uneven flow... no biggy on low powered engines blow say 600bhp:mischeif: lol! but more of a problem above.

How hard are you going to push that GT35??

On the 10v 034MS tubular ex manifolds they are underneath but that is purely because the inlet manifold prevents it from being above.

Ill post more pics when i get the wastegate fitted and welded together. Should be starting on the IM when my 90mm TB arrives from thialand and i`ll post some pics of that up too.
Not too sure on how far a gt35 can be pushed on one of these engines i know the compressor flows about 60 lb/m of air but i`ve never tuned one of these engines before i suppose im looking for about 550 hp.

Update

Managed to crack on with the fabrication and got the shell ready for paint, I`ve just finished the inside and im reasonably happy but i think i`ll swap to standox paint for the extirior panels because i was`nt too happy with the paint quality i suppose you get what you pay for. The colour code is 00E55 which is british standard white, it`s basically the whitest white you can get.






i`ll post the pics of the shell fully sprayed later this week, you never know it might be on the road by next year after all

excellent work .take my hat off to you

[Crawford_S2]

This truly is an epic build for a one man band, moocho respect to you mate!

[gnutz2]

Thanks for the appraisal. Any input to the build is appreciated

Im also looking for a 3b flywheel as im ditching the aby, i heard it`s a bit heavy and the 3b`s have a much better throttle response. i`d go for billet steel or alloy but i have a budget.

[sal_s2]

Cars coming together nicely Baz, give me a ring, pretty sure I got a 3b flywheel somewhere

Ok got the shell sprayed now and im trying to get the shell rolling so i can spray the other bits in the garage, im also getting on with the engine so i can send it away to get bored and honed or just honed depending on how bad the bores are but they dont look too bad for 180k.
Also getting a sheet of polycarbonate so i can cun my own windows out, got a cossie bar and plate rad for the boot off ebay and i`ll make the cold air feed plenum for that out of sheet aluminium and exhaust the heated up air through the boot floor and under the car and loads of other stuff but i`ll get to it soon enough.
