The ignition spec on the Integra is 16 degrees BTDC +/- 2 degrees. Typically, though, it's accepted that advancing the timing on a naturally aspirated motor allows the motor to make more power. I'm not sure, but I believe the reason is because the combustion reaches pressure closer to TDC, which means it can act on the piston longer.

My question is, would advancing the timing to the factory max of 18 degrees BTDC yield any noticable benefit? I know that this usually requires a higher octane gas, but the GS-R does have a knock sensor which will retard timing if you push it too far.

Any thoughts would be greatly appreciated.
