TX question about 13b & 13b-rew

is there any difference between 13b renesis and 13b-REW other than turbo?
it seems like rx8 makes around 200whp without turbo

The short answer is "everything".

The Renesis is 6 port with side exhaust ports, the REW is 4 port with peripheral exhaust ports. Renesis has high compression 10:1 rotors with a different seal arrangement then the older 13B. Intake manifold is totally different, REW is twin turbo while the Renesis is NA, etc. etc. There is almost nothing in common between the two.
