1987 Pontiac Sunbird GT

About This Vehicle:

2016 - After many years, I'm starting to work on this again. Going to have the transmission rebuilt and the diff converted to a Race LSD. Gutting the interior, removing the convertible top and all glass, and making it a lightweight roadster. Car will be a street legal race car, and not much else. 1/18/06 Updated my info here finally after like almost two years LOL. Put up a couple newer pics, took down my crappy photoshop paint pics. The newest pic is the Gauge Magezine shot with no front rubstrips. The other shots are from the 2001 J-bash, then again at the 2003 bash with the new rims! The turbo pics are comparing the T25 to the T3 I am using It's one of only about 1,200 Turbo GT Convertibles made in 87. It's the last year of the 1st gen, so it has the blackout style tailights (which are the best IMHO), but it was also the first year of the turbo 2.0 (still the most powerful stock J engine to date, making the sunbird turbo GT's with a 2.0 turbo and 5 speed, the fastest stock J's to date).
