Wait until the warranty is up and do a 13B-REW swap with a bridgeported 13B, GT35 turbo setup, and a great tune. Wider tires in the back. Have some fun.

I disagree.
The Renesis has more potential, and it would be a lot cheaper to just port and FI the Renesis for 500+ WHP.

:scratch: How long have you been in the rotary world again? It would be cheaper to port a Renesis and turbo it, but porting the Renesis does next to nothing for power due to the port designs. Four ports will always reign supreme when it comes to gaining power out of porting. That is why a streetported 12A will make as much power as a six port 13B bridgeported (provided the streetported 12A is a good sized streetport).

The Renesis has more potential? Are you serious? I've never seen a Renesis put down 350 horsepower all motor at the wheels by doing port work. If you want to see that just take a look at Jesus Padilla's FB. 13B (started its life as a 20B, but removed rear rotor). The Renesis would be lucky to make 300 horsepower at the wheels if you did everything you can do to it. Its simply not efficient when it comes to tuning.

Then comes the turbo setup. I've owned two FB's, an FC, and currently own an Rx8. Turbocharging the Rx8, at best, I've seen 450-500 horsepower. I have seen damn near 700 horsepower out of 13B-REW's, and about the same out of 13B-RE's. Not to mention the failure rates of turbocharging the Renesis due to its fragile design when it comes to forced induction. It was built to be an all motor vehicle, and will remain just that. I'm sure there are examples out there that are "reliable" but the engines are no where near as reliable as a good build on a 13B-RE or 13B-REW just due to what the engines were designed for.

And before you go spouting out about how unreliable the FD is remember one thing - the FD failed so badly because of its complicated turbo setup and its inability to keep the engine cool. It wasn't really the engine itself as the problem as much so as it being unable to keep cool.
