blackthorn 0 Posted January 30, 2009 Hey guys, what uprated cams can i get for a 1.8 16v gti corrado? and whats the standard bhp on a 1.8? cheers, Andy Quote Share this post Link to post Share on other sites
davidwort 0 Posted January 30, 2009 stick with the VW sticks unless your engine is build to rev well past the standard rev limit, all you'll do is shift the power band up the rev range leaving the bottom end wanting, I'd spend the money elsewhere, certainly wait until you've done everything else, like flow the head. My 2p. Quote Share this post Link to post Share on other sites
blackthorn 0 Posted January 30, 2009 ah okey doke mate! what would u suggest to do to the engine? like P+P, glas flowed, P+P inlet etc etc? andy Quote Share this post Link to post Share on other sites
davidwort 0 Posted January 30, 2009 valver is not cheap to get more power from but I'd suggest to do these in this order: rebuild bottom end (so it is known to be in good condition to take more power) OR drop in a 2L bottom end, including head if known to be good (9A from Passat or 2L Corrado, 6A from Audi 80/coupe or ABF/ACE from mk3 golf 16v/late audi) - If ABF then keep ABF cams otherwise use KR inlet cam (2L is worth about 10% gain in power and torque) then, rebuild head and port/polish/gasflow including new hydraulic tappets port and internally polish inlet and exhaust manifolds (10-20% gain) set up fuelling and ignition on rolling road IRO 100 quid (could be the best bang for the buck on any valver TBH) 10% gain experiment with higher lift cams at great expense for little in point to point speed :lol: 10% gain - all at the top end don't bother with a 50mm inlet unless you've done all of the above an aftermarket exhaust and air filter(K&N/Jetex type panel) won't do any harm, but equally won't make much difference turbo at huge expense :) or give up and fit a 1.8T :lol: Quote Share this post Link to post Share on other sites
blackthorn 0 Posted February 2, 2009 bump as im wondering what bhp the 1.8 16v gti engines are? Quote Share this post Link to post Share on other sites
mattnorgrove 0 Posted February 2, 2009 In the region of 138bhp as I recall... Quote Share this post Link to post Share on other sites
davidwort 0 Posted February 2, 2009 I'm sure you could find that out pretty easily from Google the golf was 139bhp Passat and Corrado 136bhp no particular reason for the 3hp difference, the engines are identical in every way, the late golfs even have the same sized inlet manifold Quote Share this post Link to post Share on other sites

aide 0 Posted March 27, 2009 post resurector :D andy, all top notch advice above also, if you want a mild gain on a kr then the kr exhaust cam can be used as an inlet, iirc has slightly better duration and defo improved my mid range torque on my last valver. basically you get a spare kr exhaust cam, chop the end that goes to the dizzy, and whack it in... ok that's simplified a bit, i have a guide which i can send by email if you pm me you can then flip your old kr inlet onto someone with a 2l - so cost neutral Quote Share this post Link to post Share on other sites
