Anyone recommend one for mk2 golf gti8v digi? only got exhaust system, else standard cheers Edited by: Dave
Kent GS2H gave me cracking results on an otherwise standard engine... ask GVK just how well that 8v went. That was a K-Jet though!
It wouldhave gone a little better with vernier but i didn't use one and still got good gains.. idle was still pretty smooth, although a dodgy ISV made things interesting at one point. The graphs show a gain in power from 1500 rpm up and a far smoother curve.
Do you have the graphs online? i'd like to look at them to compare, think im going to get a GS2H for mine...
To get the best gains you need a flowed head, K&N panel filter (with the guts ripped out of the airbox) & ideally an ECU rechip to up the fuelling... Cam wise id recommend a TSR 202, a bit more lumpy at idle than a GS2H, but smooth as soon as you blip it & revs out to 6500RPM instead of the standard digi trate of hitting a brick wall at 5500.... A vernier is always a good idea IMO as cams rarely run their best on stock timing. I think its a manufacturers ploy to grind them slightly out so you have to shell out another 80 to get it running right...
No, I used to... The 202 is great in an 1800 or 1900 conversion, but a bit too mild for a 2L like mine. I use a 2L block with a flowed big valve head & TSR 203 cam (282deg duration) It also has an AmD chip & the usual exhaust/intake mods... It gave 122atw @ TSR with a possible full throttle enrich problem, (as I found out later), which is about the same as most standardish (filter/exhaust) KR 16v's & standard ABF 2L 16v... Will be going on Stealths RR again soon, so I should have a definitive flywheel figure. Edited by: chrismc
brilliant! thanks for the advice all how much can i expect to pay for the head to get done? chees Edited by: Dave
If you are planning on staying at 18 or 1900 then a Stage 1 head is fine & will cost around 350-400.. If you plan in going 2L in the future then a Stage 2 head(Big exhaust valves) is just the ticket & improves top end breathing a lot...650-700 tho Edited by: chrismc
I am interested in this mod also, and have a few questions... Smithy, What mods have you done to your driver? Tubthumped, Had you done any other mods other than cam before and after? See below image for all three graphs (Smithy and Tubthumped x 2). Cheers
Looks like its a Kent GS2H for me! just sold my old bottle cap alloys for 80 quid, so im going to order one next week. My engine spec is; DIY rebuild and port job on the head, matched manifolds Weber 32/34 DMTL std 8v GTi camshaft Digifant 4 into 2 exhaust manifold Removed spikes and Machined smooth the manifold heater It seems pretty healthy anyway, the guy at the rollers said my headwork must have been pretty good as it made the peak power at 5636rpm which is a bit higher than a normal 8v. Should work well with the fast road cam, i'll let you know how it goes! Edited by: smithy
The car went on the rollers first time with a Jetex full stainless and a K+N panel filter with a massacred airbox. It had a full setup at Awesome not long before. It had the cam put in and was re-setup and the final RR readout was given.
