F22B and H23A1

[HotHordas7]

Whats the difference between the two except for displacement, and would the turbo F22B be as good as turbo H23A1. I was gonna drop a H23A1 into my 97 Accord and turbo it but cant find a decent engine but anyways I'm still lookin' in case anybody got one so can somebody answer my question please thanks

[IntegraXTR]

Not sure if this will help, don't know too much about H and F series but the H23a1 is a lil bigger I believe in displacement 2.3L and the F22 is 2.2. Both have low compression already too...sorry if that didn't help.

H23's are non vtec engines. you would gain more torque if you boosted that engine. F22 are single cam. I would boost the f22, and also has good torque numbers. now, if money isnt an issue, h23 for the monster torque.

lol dude, F22B is DOHC non-vtec also man

lol dude, F22B is DOHC non-vtec also man

lol. you're right. was thinking of the f22A.

there aint much different... i got a h23 accord... i took out the f22... i have the headers from my f22 on the h23 and and also the intake .. h23 has more hp and more torque... this probably dont even help you out.. lol

[93H22ACX]

F22 has less hp and torque to start off with... the crank and rods are the same... so internally the H23 and F22 are the same...

H23 has larger displacement, more torque, more hp. if you can get either one for the same price.. get the H23. but if the F22 is cheaper go with that.

i would go with the H23 and put a H22 head on it... its easier than putting a H22 head on the F22 block

the F22 also has iron sleeves which makes it easier to install forged pistons without resleeving like the H22 and H23
