[prNonVtec4u]

PLEASE start using the friendly search button... this has ALL been covered previously many times...

JDM F22b's head parts = H23
JDM F22b's block parts = F22A

alright thanks dude. 2 more questions is this what you have done to your car?
should i keep my car the spearmint green or paint it black? painting it will leave engine bay trunk internals of the car stock color? what sould i do

[B20F22A1]

Right know as we speak my car is receiving a new motor swap(F22b). I've hered nothing but great things about this motor . I just recently bought a P75 chipped ECU with a F22B basemap at 7,000 rev limit.... so i know I will have fun. JUST DO THE SWAP!

[prNonVtec4u]

yes, i have a JDM F22B still running off the stock pt6, all the details are on my MR page

repainting the same color is always the way to go... if changing color, then it's gon' b big $$$ for a well done job

[ti's 92 accord]

ok it will during the summer tho haha right now i have to get my car inspected and pay my insurance and than i will save up some cash and swap it

[prNonVtec4u]

sounds good

[ti's 92 accord]

i really want to tune my car up nice im tired of the turbo wrx tooling on me i want to tool on them haha you kno

[akkordlayinkit]

F22B is a good cheap easy swap. Stock ECU will work fine, but if you can find one get the P39

Current tranny will work, but if you can find a cheap tranny off a Lude Si H23 you'll love it even more.

Do it you won't regret.

Before this goes any further...


ti's 92 accord, please pay attention to this. I caught a few things in your original posts that people seem to have ignored... and it could be a very expensive lesson to learn.



The F22B is a JDM engine. We DO NOT have this engine in any car sold in the US. The 91 Prelude has a B21 engine, which isn't compatible with our cars in any way. Not a bit of it. Not the head, not the ECU, nothing.

Honda motors from the late 80's on have the displacement size in the name. F22 is a 2.2L engine. H23 is a 2.3L engine. J35 is 3.5L. F18, 1.8L. See the pattern?


DOHC is useful when tuning the cams with adjustable cam gears. The DOHC valvetrain is also smaller (the valves and springs, that is), so it's less moving mass. However, DOHC is heavier than SOHC, for obvious reasons.


The F22B from the JDM Prelude Si (the equivalent car to our H23 equipped Si, as they didn't get the H23 there) will work with the PT3 or PT6 ECUs. However, the P39 from the JDM Prelude Si would be proper.


Worth the swap? It's up to you. Is 160hp, 20hp over the F22A (as well as a lower mileage engine, if you get a good one) for about $850? Plus the cost of replacing the timing belt, water pump, and all associated seals? Clutch and axles would be a good idea while you're at it.

I don't think I'd get one. It's a nice motor, but only a small bump in power. I'd save more money for an H22 or F20B if I wanted to swap motors. If not, I'd stick with modding the F22A. At least those are extremely cheap to come by. I can get an F22A head for about $50 very easily...

[ti's 92 accord]

thanks man. but im not a big fan of vtec and if the f22b is equivalent to the h23 except for that point 3 of a liter than i want the f22b you kno what i mean

[deevergote]

.1L difference. It's not really equivalent to the H23... just the motor that went in the Prelude Si in Japan... and it makes the same amount of horsepower.


Why not a fan of vtec? Not that it matters, but I'm curious.

[ti's 92 accord]

because vtec is just a gas saver. when you get past a sertan speed vtec kicks in and adjust the cams. its just a gas saver. the h22 vs h23 is that the h22 is vtec and allows more air and gas mixture. if you bore out the h23 intake and outtake system you can get the same if not more hp at a continues speed.

[deevergote]

VTEC is a gas saver with a SOHC, that's true. to a point. DOHC VTEC is another story. VTEC provides two cam profiles at once. So you get low end power, and then high end power. With a single cam profile, you have one or the other. An aftermarket non-vtec cam will give a soggy low end.

VTEC was developed for the NSX. Believe me... it was NOT intended to function as a gas saver!
