The only problem I can see in such a swap is weight issues. The S13/S14 is a fat lady for a high revving engine. It still needs a little low-end torque to move itself around. If you want something responsive and very nervous, run a SR20DET setup with bolt-ons. Stock T25, Stock Boost, but all bolt-ons to get it breathing. Full boost at 3000ish rpm and almost instant response. That was the best move I did for Auto-X.
