It seems to me that everyone here is overlooking something. Why upgrade the engine.. it seems that everyone who has been vocal has forgotten one key factor BOOST!.. we all know that this engine is capable of a Force Induction ugrade.. aka the Legand Turbo Setup.. bam there you go.. looking at this from an Import Tuner perspective.. its great.. ( I drive a Twin Turbo Z) you need to free up the exhaust system.. gut the cats and the pre-cats.. increase the piping to like 2.5 or 3 inches.. install a high flow intake ( k/n cone filtercharger).. then start worrying about boosting.. you could install some boost jets (contact welding tips) or just get a bigger turbo.. or install ceramic bearings etc.. there is a host of possiblities there.. then get a boost controller to jack up the boost.. couple that with an Air/Fuel Controller and well you have an .. excuse my french " a Raped Ape "... this car will be freakin awesome.. as long as we can upgrade the clutch .. heehe what do ya think.. we could also place the intercooler in a way for a bigger ram-air effect.. woohoo.. this sucker would be FAAAST and EFFIECENT!
