Whats the highest compression with pump gas?
Im selling my h22 civic and thinking about swapping a b-series vtec motor into my ek. i would like to go allmotor, but i would also like to know what is the highest compression i can use with pump gas without knocking/pinging. im aware that other factors must be upgraded (internals/fuel delivery). any answers will be appreciated.

I've seen guys run 12:1 CR on 93 octane.
Get a good standalone and a REALLY GOOD tuner and you should be fine. Just don't be reving to 9k rpms daily.

let me ask this...whats the difference between a b18c w/ 12:1 pistons rather than a type-r motor stock (other than lsd and cams)

head is mildly ported, better oil pump, lower compression, different combustion chamber size, intake valves, crank. thats about all i can think of off the top of my head.

Re: Whats the highest compression with pump gas? (ErikDaGenErik)
when people are saying they are running 12.5:1 on pump gas. Are they referring to static or dynamic compression?
