I've had this GTA since 1994 and it's by far my absolute favorite performance car when it comes to looks, and that goes for all of the older and newer car offerings. It has a clean and timeless looking beauty that's hard to beat, imo. No, it's not the fastest or quickest by any means, but I've transformed it into a machine that can definitely keep up with most of the newer performance cars on the market.
It has a 383 cubic inch crate motor that's rated at 440 horsepower and 445 ft lbs of torque at the crank, a FIRST Performance intake system and a Holley HP EFI ECU handles fuel management. Exhaust gas is expelled through Dyno Don 1.75 headers, custom 3 inch exhaust piping with high flow cats and exits through a Flowmaster muffler. I chose to run cats because I can't stand having my clothes smell like raw fuel, and personally, I think they help produce a smoother exhaust note by eliminating that tinny rasp sound.
There's a ton of other things done, but I've listed the major mods that most people care about. I didn't build this car to be a straight line racer, mainly a fun street car with gobs of low down torque that can be enjoyed out on the highways, on curvy country roads and twisty mountain passes all while looking like a beauty queen.
