Thank you all for the usefull info on where to buy motors, and opinions on engine swaps. I forgot to mention my ga16de has 140k on it, and I am struggling with the thought of spending the money to fix it or to get rid of it. It was wrecked before I bought it, however, I am not sure how bad. I like the little car, but I want a fast fun car, and if I am going to have to be swapping motors every 30k, it would seem like more work then fun.(the reason I say this is because I haven't found an engine with under 100k on it) The car impressed me with it's ability to keep up with my brother-in-laws firebird (3800 series V6) although I had to drive it quite hard to accomplish that. I don't know if I should try and build the car up, or sell/trade it in on another car. I don't want a honda because they are notorious for lacking in the torque dept. So my nissan seemed like a viable option. Oh well, my poor little ga16 is probably beyond help. And keeping it, well, we will have to see what cost I will have to endure before I make that decision.
