from what ive read any of the rotors in the engines 86 on (well im not sure about the rx8)

the s5 n/a rotors have a 9.7:1 cr which is the highest available i belive would be your best choice IMHO

You can use the 86-88 NA rotors with no problem.

If you want to upgrade and get the higher compression 89-91 Na rotors you need to also get the 89-91 NA flywheel and front counterweight.

Just finished building a NA PP 13B for a race car with Renesis 10:1 rotors..

The apex groove had to be machined to take the Hurley seal as the Renesis groove has a taper but other than that no ish. Motor gets lit this week
