Only the input shaft is different....it'll require a special Pilot bearing i the 2.3L that accepts the V8 input shaft. Everything else is basically the same except gearing in the tranny.
yeah, you will need a custom Pilot bearing, i think rapido makes one. He will have a lower first gear though so it wont leap off the line like the 2.3 T5's do but it should hold up better and probably be a better set of gear ratios for a turbo setup
