The parts themselves aren't what determine how long the motor's gonna last. The main thing you have to worry about is getting enough fuel into the motor.

Ideally you want to run an upgraded fuel pump, larger injectors and a programmable ECU (in the case of a non-OBD car like yours Zdyne is the way to go). After a couple hours on the dyno it'll be running very nicely, assuming you picked a good tuner.
