Re: High Compression Pistons @ Twin Spark 2.0
What sort of power output are you looking for? 12:1 CR is very high.
Sorry, I didn't read your first post properly. If you will be using the car everyday its best to keep under 12.1 CR, then there will be no need for high compression pistons.
I would suggest getting the head ported and the inlet valve diameter increased slightly. Then remap the engine again. You could achieve a significant gain in power without losing the 'driveability' of the engine.
