hey guys i have a 1990 hatch with stock b2. was juggling betwen boosted D and N/A B. might go with D. i bought an a6 head while back with intentions of putting it onto my b2 bottom. but because of high miles was discouraged from doing it. someone i know is putting jdm d15b vtec head onto an a6 bottom for SC project. If i convert to MPFI and run my A6 head on his d15b bottom end wut do u think my results will be? wut do you predict in HP, TQ, they both have 2 different redlines...wut wil a safe one be that can allow most out of the bottom and head. i want to buy the head gasket, adjustable cam gear, full SI injection and ECU and run it like that. thanks.

 

I'm pretty sure the bottom end is same as a 1.5 vx, So you are only adding Mpfi and the a6 camshaft. So you would probably only notice The MPFI change.

 

the A6 bottom will NOT be reliable over its stock redline. trust me. i blew one all to hell.
the A6 top is the same thing. valves will float after 8k.

just get a sohc zc..same as a A6 but better comopression and a better cam for turbo. plus you can get one for 400$.

thats what i did anyway.

 

ok so if i did use the A6 head with a d15b bottom end... i couldnt even rev the d15 to its red line,and wouldnt be getting as muhc as i can from it. thanks guys. basically just wanted to know if its worth the trouble or not.
