Use the S5 rotors, flywheel, and front counterweight if you can find them cheap. They're lighter and have higher compression. Honestly, you're building a non-turbo engine. How much power do you want? If the S4 parts are in good shape then measure the engine clearances, replace what's worn, and run it.

Have you dissembled your engine? Inspect your parts first, then make a "replace" list. If this is your first rotary engine rebuild you should keep it simple and rebuild it to factory specs. Do you have a copy of the FSM engine chapter?
