I had an 89 probe GT, I traded it in with 166k miles never had any problems with the engine. I beat on it hard too. The rest of the car started going. Heater fan, windows, headlights all inoperable. Still ran great. I had it in Germany for 2 years and remember driving to Munich with the cruse set at 100mph with the a/c on. The boost would peg on every hill and I would pass everyone. LOL that was fun.
