Hi I am just after a small amount of info for getting a little but more poke from an abf which I am most of the way putting into a mk4 polo First off is the flywheel is there a aftermarket lighter flywheel available or another type from a different engine etc? Or is it a machine shop job? Second up is cams I want to change out the factory ones what have other people used or recommend? I have been looking at newman cams which they class as tarmac rally spec has anyone used these before? the car will be running on jenvey itbs and I think mega squrt for management Any help would be great thanks Chris
I'm just about to put an ABF in my Corrado. Going to be using a G60 flywheel which weighs in at 7kg versus, I think, about 9kg for the ABF one. I say it's a G60 flywheel but I bet other engines use them, I believe it's the same as the one bolted to my Corrado's original KR. Both engines are still in their homes so far so I haven't had a chance to compare them. I don't know about tuning the ABF but I hear the cams are pretty damn good already. Toyotec's a Megasquirt wizard so it may be best to find him on here, he's never far away..
Lighten and balance flywheel to about 5kg Chip the Ecu Modified airbox with cold air feed Decent exhaust (Jetex etc) Port and polish cylinder head (careful if wanting to change cams) It's not the engine which is the problem it's the gearing, 3rd being way to long. Change the gearing to a 3.94 FD. My advice is not to bother with cams unless you are prepared to go big cams, big headwork, ITBs and standalone management...and even then, a high compression bottom end is really needed or you are wasting the cams Mine just pulled 162.2 bhp on the TSR rollers withthout any headwork having been done. Not bad for a 20 yr old car, 150 bhp from factory! But like everything, it all costs coin and the engine needs to be healthy and well maintained.
Fit engine as is, and get a short final drive 3.94 or 4.23 with a diff fitted. Get used to it and take it to the track to learn the how to drive it and critique it properly. Then tune the standard ECU or standalone to deliver maximum response. Get used to that. Then get the engine to breath a bit more at higher engine speeds with Cams. More? Throttles ( need to be running a SEM) More? High compression and gasflowed plus valve work, plus your previous step with a remap. This means a proper rebuild, blue printing everything.
I can never find his posts about his Mk3 can anyone give me a pointer for the search function, keywords etc? Edit: found a couple of threads now.
Somebody say my name three times whilst looking in a mirror? I'm still about...lost a bit of interest in cars after getting banned a few years ago. Got back into bikes. Toyotec is right...I've been out on my Speed Triple R lol I still have VWs though
