Hey guys, about to buy some more parts for my car, 2005 G35x. I read some thread where the spacer was the most recommened, and the mrev2 was not really recommended. I didn't see anything factoring in with Vortech, though. Is there an optimal setup for non-revup and Vortech?

 

more air the better. it'll make more power at a lower psi.

if youre automatic, forget the mrev2. if you're stick then get the mrev2. mrev2 doesnt do much for non-rev up motors.
