I own the 1993 1/2 model and I was curious as to why there is a half year model, and what are the differences between it and the standard 93. Also, are they more common, or do they have other differences not associated with the engine?
I think the main difference is AIV (PAIR in the FSM) removal and the change to a lowport layout. Someone correct me if I'm wrong but I think that's it. I know that it either happend then or in the 94 model year. If it was 94, then nothing changed in your engine.
