GC8 the first generation Subaru Impreza WRX STi:

Also available was a WRX Type R V-limited, in version III. It has a WRX motor with no forged internals like the STI, and it misses out on the 4 pot front brakes as they are to be installed by rally teams. It has a roof vent and is lightweight, making a good base for a rally car.

Version III STI runs a VF23 IHI ball bearing turbocharger while the JDM non-STI gets a VF22.

Version IV (09/97 – 08/98) – GC8 E
Power remained at 280 PS but torque was raised from 253 lbs./ft of torque to 260. Forged pistons were also added.

The interior and the cockpit were changed into a newer design along with the new “White color” gauges.
