Re:what octane

Higher the better, JDM engines run a higher compression ratio and use 100 ron.

Re:what octane

why not just keep a 55 gal. drum of VP at home, anything over 11:1 I would use race fuel or just retard the timing a few degrees (so you dont ping it to death) and run high octane pump gas

Re:what octane

Just to clarify, higher octane does NOT equal more power. You should only run the minimum octane needed to fend off detonation.

This is true. A friend of mine just went to the hondata seminar, and he said that they recommend tuning for the lowest octane possible while still avoiding knock.
