I wouldnt build a rotary, I would do a V8 setup. Ive heard that if you dont run them into the ground, 3 rotor engine's will last a long time with little maintnance, but that might have been just fanboyism bs the the people on the forum were feeding me. I think they are sexy cars. but if I was going to get one and plan on doing a swap anyway why not get a dodge daytona? My step dad had one and it was pretty quick I guess, last time I rode in it before he sold it I was 13 and I didnt really care about cars then. Are they 6 cyl or 8 cyl engines?
