Hey guys, Ive got a 66MM S2 throttle body, and I would like to get the new S2 Ultra Street Intake Manifold. Its the one with the 74MM opening, not the 90MM one. Will the difference in size be a problem? Or should I get a bigger Throttle body. I know all about porting out the intake manifold but this is the other way around. Any help is appreciated.

 

I trust you have a BUILT engine that you're putting that S2 ultra manifold on ? no you'd need the Skunk2 pro 74mm tb to truly benifit from it.
