Actually, I dont believe mitsu 20'g turbos are available in a ball bearing trim. The stage 3 kit includes this: 15psi wastegate actuator, 410cc (i cant remember exactly, maybe smaller or larger), a "black box" fuel computer to trick the ECU, and upgraded internals (pistons, rods) and a clutch upgrade is definitely recommended.

91 awd: 60-1, 880's, E-Prom, etc.
93 awd: JDM 6 bolt, K&N, full exhaust, Wally 255, otherwise stock.

R.I.P. the original "Factory Freak"
15.5's with short ram and catback only
1996 RS 5-speed
