Thread: stock gtp

read this, it should answer any questions you have, although its mainly geared towards the 97s-03s

the 3.6 would be the recomended size, remember though you have to get it tuned, and you should scan for knock before and after

no problem man, and if your reading through that thread i posted keep in mind the general rule of thumb is with the gen v blower ( your supercharger) is that you add .2 to the pulley size of the m90 s/c (99-03 blower)

So the typical 3.4" most people get to...you go with a 3.6".
