ok well the ones I have known had issues but they were older non injected ones..anyway not denying the rotary as a performer, but I dont think they are any better than a well setup 8.
And aside from traffic light races what else is it good for, a V8 can be use for a variety of purposes in just about anycar of any weight..a rotary is fast in a lightweight car and is good for nothing else..
Also a brand new V8 crate engine is about 6k as well and is easily replalced or fixed at any mechanic anywhere, your rotary f**ks up anywhere other than a major city and your stuck shipping parts everywhere..
The rx7 is awesome but that is all...a V8 makes any car awesome and im sorry if this offends you but anyone that denies the LS chev engine its glory is more of a knuckledragger than those they claim to be superior to..
