As the title says, Im looking for pistons with the same compression as the pct pistons (CTR) but not knowing what to compression ratio to ask for when ordering.

I would just get the CTR's but Im goin to be spraying so i want to keep it safe.

 

it depends what motor setup ur using to be able to tell u ur comp ration... i would just try a 11.5 or 12:1 comp though
