MZpog 10 Posted April 17, 2015 My Corrado is running pretty much the best it ever had and mechanically/electrically wants for nothing (touches wood), so though I best do sommat. I was wondering about maybe getting the head flowed to pep her up some more but have no idea who's recommended for such a job and what gains could be had. When I had my old MBG flowed by Peter Burgess (a master with the B series engine) it gave 30% more BHP at the crank. Quote Share this post Link to post Share on other sites
Roger Blassberg 0 Posted April 22, 2015 Your first sentence makes no sense at all to me. There is an old and wise saying about not fixing something that isn't brokem. I think that you will be disappointed if you expect 30% more power by gas flowing a 16V head. The old B series engines were fairly crude affairs off the shelf with siamesed inlet ports and not cross-flowed either. The valves were substantially shrouded by the sides of the combustion chambers so there was a lot of improvement to be made. The 9A or ABF heads are good in standard form, maybe use slightly higher lift camshafts if you want to experiment - that modification can be reversed if it doesn't work out. I have a pair of ABF camshafts if you want to make me an offer. Best wishes RB Quote Share this post Link to post Share on other sites

Done a bit of research and gains suggested are 5-10% so think I'll find something else to buy the C. Quote Share this post Link to post Share on other sites
