I have owned this super rare 1992 GP since December 1997. It has every possible option for an STE in 92 including the 4 cam 3.4L DOHC Chevrolet powerplant and the M284 West German Getrag 5 speed manual transmission. The only option missing is the HUD. It is one of 57 built in 92 and probably the highest option car out of all of them, so it is most likely one of one. I have done intake and Flowmaster 40 exhaust, suspension and gauge mods. It has 18" wheels with Toyo Proxes tires, BellTech front springs (1.5" drop), a custom EEPROM chip and a whole ton more. It is now making between 255 and 265 HP and I need to get it back to the dyno for its third set of pulls. I estimate the 1/4 in 13.9, to 14.0 based on other factors and street runs.
