I think GTP SE is right on. From what I've gathered, you will at least need a fullsized intercooler and rockers (more likely a cam) for a 3" pulley. You would really want headers at that point, as that is about as far as a downpipe and PEMs or a Plog will go. A cam would probably make it easier. Intake side, you would benefit from a ported blower and a throttle body upgrade. Then a good tune and a new tranny.But it sounds like you are falling for the trap of trying to hit a certain pulley size. The pulley size should be low on the priorities. Get your supporting mods together, tune for ideal A/F and timing and only go as small on the pulley as you can without compromise to your tune.
