RX-8 parts/ compression ratios
i was wondering what rx-8 parts could fit in the 13B. i am looking mainly at internals. i ask because i saw on a website the E shaft from a RX-8 for the FCs. what will work? what won't. i am mainly looking for a higher compression rotors. for a turbo project. before you correct me i am planing to run E85 for a school research project. also if any one could tell me the ratios between the years that would be great. i know 86 to 88 is 9.4:1, 89-91/92 9.7:1 and the rx-8 is 10:1, i don't know about the FDs. if the info is already on the site please post a link.

FD is 9:1, same with turbo S5, turbo S4 is 8.5:1
the rx-8 engine is still a 13b for the most part.
rx-8 parts are expensive and tests by mazdatrix comparing S5 9.7 rotors to rx-8 10:1 rotors show no HP gains at all.
just use the 9.7, the .3 is nothing your going to notice, and will be a waste of money.

That is what i am using in my FD
