Is it possible to increase the compression ratio of the engine?
I discovered that the type-r engines usually have a higher compression ratio to give a high hp. So, I wonder whether we can increase the ratio to gain performance.

It's already 10.5:1 which is pretty high. You could probably get it up to 11:1 on 93 octane but anything higher would likely cause detonation if you didn't run race fuel.
Realtime runs 12.5:1 on their TSX but they also use 112 octane.

I use Sunoco 94 on a regular basis up here. :P
Does lower octane make for a cleaner burning fuel?

putting higher octane gas in your car does not affect your car's comprasion ratio (just in case anybody read the above threads incorrectly).
another myth... placing higher octane gas in a car that requires regular octane will increase performance.
this is completely FALSE.
lastly... what octane method are they using... 93 octane here (USA) is the same as the high octane gases found in europe.
Not to mention, just about everywhere around where I live you can get 107.

You could use a Spoon Head Gasket and not have to use higher octane (without worry of detonation).
