For those who aren't familiar, the Saab 900 Turbo is equipped with a twin-cam 16v 2.0 liter inline four, factory turbocharged with a Garrett T3 and intercooled. Factory performance figures were 160hp/188ft-lbs starting in 1985 for the US. This referred to as the "classic 900", in order to differentiate it from the 1994-1998 Saab 900 produced in conjunction with General Motors.
The Grey Ghost is my 1987 Saab 900 turbo convertible that I've owned for 8 years. It has gone through many iterations and several modifications inside and out. My father and I do all the work on our own out of our garage, including repair, maintenance, custom fabrication and installation, paint, bodywork, and more. This car is equipped with a rare factory Airflow body kit imported from Germany in 2000 (only a handful have made it to the US). It is the first year of the 900 convertible and includes many rare parts that I have collected from classic Saab history.
This car recently hit the dyno and made
335whp/330ft-lbs. With 15% losses, it makes around 400bhp at the crank, up from 160bhp stock.
