i drive 120 mile round trip for work right now, was wondering if a Si or a RSX transmission will swap right in, or almost swap in or no way possible to put in. CAI might be a problem

 

1st off, u might want to state what car you own. From your name im guessing u have an Ex. Your EX has a D-series, and the Si/RSX have K's. Therefore no you cannot swap tranny's. u will need a K engine, to use any K tranny. Just like any other honda engine/tranny. The tranny will only work on the engine code its designed for( other than H/F series) and the fact no other D16 series tranny will work on our d17's
