well i was under the impression that if your car runs real hard and then you turn your engine off right away, the oil in the turbo cartridge will thicken. if this happens the 270 throw out bearing will get clogged up pretty bad. its only like $100 off of ebay, might as well. my friend has a greddy for his vr4, it is pretty nice. im sure u can get like an amexi for pretty cheap too.
