hey guys out of curiosity can u put ka24e pistons on a ka24de to get high compression and install a turbo kit on top of that and run 94 Octane gas from sunoco or will it be to high of compression to use gas in general? ---

theres some magical numbers out there for maximum compression in the cylinder per fuel quantity/octane and timing, adding boost will increase that compression so the answer is usually to use lower compression pistons however there’s usually a safety margin which is how 9.5:1 to 10.5:1 engines can still run boost, just low boost like 4-6psi … the benefits are very quick spool and immediate power without such a power hump like on large turbos, but you sacrifice from your total achievable power if you want good midrange and response then a high-comp turbo setup is good, for outright drag speed you want less compression and more boost
