My engine is toasted, it still drives but appex seals are shot and I have no compression. I had nitrous on it to the tune of a nitrous express wet system jetted at 75HP or less depending on my mood. The nitrous was a learning experience for me and my v-8 buddies. They know a ton about nitrous on V-8's but had never put it on a rotary. Before my sixports were operated of the air pump I always ran into nitrous backfire, one time it even blew the intake tube off the throttle body and tore up some hood insulation. When the sixports were opened the nitrous worked great. I did the atf thing and it worked great. I put sinthetic blend oil in it a week before I raced it the last time and performance dropped off in a big way it only ran 17.40 with nitrous hit at half track when it used to run in the low 15's without nitrous amongst crazy wheel spin. I want to put in another motor but don't want another stock motor with bolt-ons. A ported NA motor would be okay but a turbo motor would be better. I need your suggestions on what to do , what combonations work and how much do they cost, also the best places to get rebuilt motors, and the work involved. PLEASE GIVE ALL YOUR SUGGESTIONS OR OPINIONS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
