H23 or F22b dohc?

[FIPD33]

im planning on doing some work to my cb7 but dont know which would be better to do. H23 turboed or F22b dohc turboed? my cousin was telling H23 with turbo and someone else was telling me H23 with H22 vtec head so i want to know your opinions

H23 with H22 head is notorious for spun bearings

h23 and f22b are basically the same motor (besides that 0.1 liter). Although both have their ups and down, all in all they aren't too different. So I'd stay with the full motor (either f22b or h23), keep the head on, and turbo that puppy

H23 has FRM sleeves. F22B does not.

so that make h23 FTW I can wait till I can afford to get mine. I always wanted the H23 to be different cuz most accords guys have a h22

ok... dumb question here.

what are FRM sleeves ??

sorry to thread jack.. i just haven't seen that before or heard about it.

[deevergote]

Fiber Reinforced Metal/Material (depending on who you talk to). They are strong, light, and have good heat dissipation properties. The downside is that most forged pistons will NOT work with them. There are only a few companies that make FRM compatible pistons... If you want to run forged internals, your best bet is to resleeve.

With turbo, non-FRM sleeves are generally preferred. You can put forged pistons in stock non-FRM sleeves and run higher boost. The sleeves will usually hold up longer than the stock internals will. A full resleeve is still preferred for serious builds, making the engines pretty much equal.

ok.. so a f22b dohc is a better option to through a dsm turbo setup than it would be to throw one on a h23 ... right ??

That's a yes, get your cylinders honed and go with a slightly larger bore on the pistons (85.5mm) if you plan on doing a rebuild. Or go with the F23A block and F22A head, then you get a little more displacement... you can prob. hone that block to 87mm w/o a resleeve

[deevergote]

Honestly, if you want to do the DSM turbo setup, and your F22A is in decent shape... just keep that. The benefits for a cheapie turbo build on a swap aren't really significant.

If you keep the F22A, that's $800+ that you can spend on quality turbo parts. $800 will get you a NICE t3/t4 turbo.

i wanted to swap the motor and get a 16g turbo with 3 inch piping and run it at 10 psi. they told me the h23 will give me more torque than the f22b dohc so that if i can find a h23 then to go with that better. i want my car to be a nice little quick daily driver i dont want nothing crazy

[tunerman]

I'd say the h23 is better than the f22b from an n/a stand point. But since you want to go turbo, the f22b is the better motor.

[FIPD33]

yea i think ill stick to the f22b dohc. thats what i was planning on doing instead of h23 but i wanted to get some fellow cb7tuners opinions on what i should do

[deevergote]

I still say F22A. Turbo will give you torque. When turbo is involved, .1L means nothing.

Hell, the 4g63 you're getting that 16g from is a 2.0L

ok... i already have the f22b and its gonna be swapped in the sedan anyways and the dsm turbo and all the stuff to go with it is free. just need the ecu. but thanx for the info !!!
