3rd generation on a 05 RX-8 ?
 

I have an 05 RX-8 automatic and I've already put 2 new engines in 4 years. I want to know if I could put a 3rd generation rx7 engine (motor) on my car. Would that be a good choice, can somebody tell me if it would fit or does anyone else have any suggestions on what to do.
Let me know please
Thanks...
