In order by date (oldest -> most recent)
Replaced transmission the day I bought it (down in WV at his shop) along with front and rear main seals.
Rebuilt Clutch Slave Cylinder.
Rebuilt Clutch Master Cylinder.
Head gasket blew shortly after I bought it.
Engine started to knock and lost a lot of power apx 1,000 miles after replacing head gasket.
Distributor went bad.
Seized brake caliper in the rear.
Installed X-Drilled rotors and performance pads all around.
Swapped engine and tranny from my 1990 900T. Donor motor had 200k.
Replaced exhaust.
Shift linkage rod bushing failed.
Ignition Key cylinder was faulty.
OK... this car has been a serious lemon, however... it is my dream car and it has 0 rust on it. I bought it knowing it needed a tranny, however the rest of the problems have been totally uncalled for.
The previous owner obviously didn't take care of it, and probably beat on it.
It is in good hands now as I have 3 other Saab's including a 1989 900T, a 1983 900 4 door, and a 1973 Sonett III.
I fix everything on my own, and parts are very cheap.
The car is finally coming together and it is starting to behave like a Saab should. It just needed a lot of TLC.
Overall, the car is an excellent car and it is VERY fast. I am currently running 18 psi of boost and have many performance modifications. I am very easy on it though ;) I only use the power when I need it hehe.
SPG's are sexy, fast, luxurious, comfortable, and handle like nothing else. They are great cars.
Just a guess, but perhaps problems such as the headgasket and knocking could be attributable to the 18 psi you are forcing into a 200k mile engine which probably has inaccurate sensors, unbalanced and dirty injects, ect...
