Question Are RX8 parts interchangeable with RX7
What are engine parts in the RX7 that can be interchanged with the RX8?

Just about nothing.

Maybe the spark plugs.

so far I found that the rotors and the e-shaft are interchangable. I bet theres a couple more, not much.

there are little parts you still need to make some of these Rx-8 parts work. check in the rotary car performance section.

as far as sensors, manifolds, etc none of that will work. the renesis is so far ahead of the old n/a engines that there is really no comparison. just about everything is a more sophisticated design.

The rotors do not just interchange. They can be used, but there is more to it than just using renesis rotors in place of 13B rotors.

Oh yeah, I am running renesis Stationary Gears, the fronts have to be modified to make it work though.
