im gonna be building a b20vtec from the ground up. 93 octane is the highest available daily, so im thinking of between 11.5-12:1cr.

what kind of power are you guys making on 93 and how high are your compression ratios?

thanks

 

YOU NEED TO HAVE IT TUNED TO FIND OUT

 

11.6..195 pump gas

 

93 octane sounds good if you dont go any higher than 12:1 jus tune the **** out of it

 

11.5-11.7 ,,,,,,240.9WHP corrected

 

I am getting away with mid 11's on really shifty 91 octane.... timing is a bish tho... mid 11 -12 should be doable on most 93's based on what I've seen.

what kind of timing did you end up pulling if any?

im aiming for between 11.5-12:1 but i dont wanna have to start pulling timing, thats just lost power. im aiming for around 250+hp with a b20vtec 2.2L stroker

thats no small feat because if your want to keep it together long your already losing a thousand or so rpm you can turn the engine. so it has to make the power sooner without turning the **** out of it, but it can be done with that compression you just need the right combo of parts

 

i dont really expect the set up to last to 100k, ill be happy with more like 60k. its more of a "i bet i can do it" kinda thing that will be a fun toy till i kill it

 

go dyno

 

16 to 20k would be more realistic. to make is last longer depending on wear you would want to pull it apart and check everything and re-ring it and slap in some new bearings to keep it going anywhere close to 60k
