You all are idiots. the right V8 will overpower ANY rotory you have. Even a 20b turbo wont give out as much power as a modified v8. And you all must not read around. You can put a v8 in your car and gain MAYBE 150lbs. And that is NOt throwing off the balance. You can put a v8 in a TII and even make the car LIGHTER then it was stock. SO get off the V8's. Plus, i have a V8 in my 7 and all my fiends have a 7. I can either hang or BEAT them on the corners, and on the strait ways i can eat them all alive. one of my friends has a TII with about $15,000 of mods to it. Plus you all say its killing the car. Maybe some of us can afford to keep the rotory running. Stuff for those engines are expesive. You can go down to almost any autzone or pepboys to get what u need, (i recomend using summit for all your parts though). So get off this guys back. V8 will do just fine in a 7. A v8 will outperform any rotory. And like i daid the weight differance isnt that much. 150lbs...thats al. So before you all start talking crap...do the research. and if any of you are EVER in Ky, bring your 7 and ill show you what a v8 can do. BIOTCHES
