What about the mileages on the motors? If the 96 was to go down, parts are scarce as for heads etc. 93 seems readily available. One fear I have is doing something to the 96 that would greatly devalue it such as replace/rebuild the motor or swap to a 95 setup and harness. I don't kill the car and enjoy semi-daily driving, but I would like to do a few open track events etc. I don't plan on modding past anything that I couldn't remove, but there's still the fear of ruining the car.
