most all 4 banger honda engines are 240cc

RDX has 410's @xenocron.com for cheap.

Ok. That's what I thought. Now can anyone tell me if stock injectors out of a stock 1990 accord EX motor are 310cc's?

Most D-series injectors are 240CC, but Y7s and D15B8s are only 180CC, D15Z1 VX injectors are supposed to be 190CC.

No, the F20B didn't have the 310cc, but the H22 did from the Prelude

builthatch

never heard of 310cc. do you mean 345cc outta 92-96 vtec prelude? h22 after that had 280cc.

i agree with you. for years i thought they were 345cc and that is what was in my head, but after you said that i remembered that accel tested the injectors for practically everything at one point. their specs are sometimes about 5cc less than what we are used to seeing but the general idea is there, close as you'll get, really.
