Bone stock these cars were rated at 245 horsepower, but tests by several magazines proved they were actually closer to 275 horsepower. With minor bolt-on modifications my car is currently in the 340 horsepower range.

History

I purchased this car in the fall of 1995. It was completely stock except for a 237 Fuel pressure regulator that I'm guessing a dealer installed at some point when it was in for servicing because the previous owner was not a "car guy". He just liked to drive the car, he knew nothing about it.
The car was repainted at some point before I purchased it. The original laquer paint on these cars was known to go bad if it was not given alot tender loving care. The current paint is a basecoat/clearcoat finish.

Future Plans

My next upgrade will be a larger turbo. I am not completely sure which Turbo I want but I am leaning toward the TE-51 for a nice street/strip combunation. Along with the turbo I'll need a a little looser torque Converter but I'll make the decision on which on after the turbo is in so I can make a better judgement on what sort of stall speed I'll need.

Drag Racing

My best 1/4 mile time to date is 12.806 at 107.42 MPH.
