i personally would not put a V8 in my seven unless i was gonna make it an all out drag car not b/c of the weight bull crap or anything like that its just easier for a v8 to be a drag car then a rotary..But since im not and love my lil PIA motor i will keep it in there..

But pretty much its all about what you want what your goals are and how much money you have..I have seen this "V8 sux" no "rotarys sux" to much..So to each his own....
