Very good tuning with a T-78 with would be ok but they are generally known for more drag racing since they spool slower. A RX-6 or T04E would be your best bet if doing roadracing and autocrossing. Both support about 380-400 rwhp at 15 psi and spool very quick. XS turbos are watercooled which helps reliability. If you have a problem with the RX-6 and need it rebuilt, Apexi won't cover it from what I've heard and you'd need a whole new turbo. The XS turbos are very cheap to rebuild. The T-78 is more of an all out brute-power turbo and can be uncontrollable if not used to that kind of power. I prefer the smaller, quicker spooling turbos for street use and road racing.
