So far I have AEM CAI, full cat-back, and polished head. WE want to put polished GSR intake manifold on a B16A2. Do I need an LS or GSR fuel rail? I know the manifold bolts right on but injectors are located in slightly different places.

Also, in your opinion, what should I expect from this (horsepower-wise). Thanks.
P.S. My boy put it on an LS, and that bitch was backfiring and sounded like a rocket...the kid didn't like it but that was non-vtec engine. I think as soon as vtec kicks in I shouldn't have any problems with it. I know it's going to run little rich but what the hell..
