Hey friends I would like some help! I have a Honda civic 91 HB with a D15 engine and I want to swap it to a D16y7. One the problems I'm finding is the conversion of the D15 PGM-Fi to the D16 PGM-FI There is a hug difference between these two Intake manifold. I would appreciate if you guys could give me some tips or links to website that could help how to do this swap! Thank you very much in advance.
