if you go and look at the japanese tuner websites you'll see that an engine rebuild to closer tolerances is stage I for the Rx8. the factory engines are either a little sloppy with seal clearances, or worn; take your pick

stage II is the ECU tune, with an intake/exhaust.

stage III is the turbo/supercharger, depending on the shop.

due to the "cut off" seal, which is needed for the side exhaust ports, the Rx8 rotors are the only ones that will work in the Rx8 engine. with FI the tune and selection of parts is important.
