--- That should net you around 11.45:1 C/R. The only thing higher would be PCT pistons (jdm CTR), which would put you close to the pump gas threshold at around 12.1:1

- You could choose to go with forged pistons at a higher C/R if you want to run an octane booster or race gas.
and when will people realize that CTR pistons are MUCH HIGHER COMPRESSION that whats published on the internet.
