H22 vs H23

[turbomaxx]

hey guys im starting to think about swapping my accord. I notice that a lot of people are doing h22, but some are also doing h23s. could someone explain the differences in these motors? isnt a h23 just a h22 head on a f22 bottom end? or am i wrong? also how much power would a h23 make vs the 200 hp of a h22.


thanks for any help guys, i really do appreciate it

the h23 was only made for the prelude in the US 92-96
h23 160hp non vtec dohc 156tq
the JDM f22b 160hp non vtec dohc 145tq basically a h23 head on a f22a block. same horsepower less tq. open deck design as with the h23 closed deck design
the h22 has 190-210hp depending yr, model and what not. some come with open or closed deck depending on yr. all these motors are good it all depends what u are looking for. (driving style)

if u have the money go for the h22 but the h23 isnt that bad and it bolts right up.

also h23s are harder to find. not that hard but not common like the h22

There are no JDM H23s, so finding one that isn't beaten to shit by US drivers is difficult. The F22B DOHC is pretty much what the Japanese had instead.

H23 is the Prelude Si motor. It's non-VTEC, and makes 160hp. A nice upgrade, but I wouldn't look for one, myself. USDM motors are hard to find in good shape. F22B DOHC for boost, H22 for NA (H22s are GREAT motors, but expensive to take beyond about 200whp). The stock F22A is actually a fantastic motor... very underappricated by most CB7 tuners!

sorry for thread jumping but witch one is easyer to install??

[turbomaxx]

well how much power could i expect to make with a F22?? i wouldnt mind building one, but i really heart vtec...

[tunerman]

from the ludes i've seen, the h23 ludes are way faster than the h22 ludes.

for reals? dang! im probably getting a H23 next week for 500! it includes tranny, engine, and ecu :http://sfbay.craigslist.org/eby/pts/...39.htmlbouncy:

Both are the same. H22 pulls top end H23 is more low end. Both make power in different areas. Tq figures are really close. Both motors run the quarter mile with a couple tenths apart.

My friend runs a quarter mile within one second of me, and all he has is cheap bolt-ons on his F22A1.

H22 is the more powerful engine. H23 has a little more torque. The VTEC point in the H22 is set higher so you can feel the transition (that "kick" you feel is what sold cars). It's actually a bit higher than necessary. A lower crossover would make for better shifts. If you shift out of VTEC with the H22, you're losing power.

The F22A head flows VERY well. I've heard this from two seperate reliable sources. Bisi Ezerioha (Bisimoto on here, professional racer and owner of his own company) is making about 400hp at the crank (340whp, assuming a 15% drivetrain loss). His motor would hypothetically drive a 2600lb CB7 down the quarter mile in about 11.3 seconds.
I've seen fast93accord's car run the quarter in 11.7. Fully built and boosted. I don't know how much power he's making, but it has to be well over 300... possibly approaching or exceeding 400.

How much could YOU make on an F22? I couldn't say. To make lots of power, you need lots of money and proper planning (planning is more important than money, honestly... know what you're doing, and know what is important, and you can save a LOT of money!)

yup, but there are edm h23's. so you can find a low mileage h23.

i believe those are the h23's hmotors sells, but they advertise them as jdm for some reason.

they both require the same steps for swapping(h22 and h23). just no vtec for the h23.

Bisi is the reason why i want to stay with the f22! even tho i know i will never be able to do what he does but it still gives me hope!

Well, the ONLY JDM H23 was the H23 VTEC found in the 6th gen AWD automatics (I heard they were only wagons, but I think someone recently told me there were sedans as well).

Either way, the H23 shares the same FRM sleeves as the H22, I believe... That means running forged pistons is difficult unless you go with the limited selection of compatible pistons, or get a full resleeve. The F22B DOHC does not have FRM sleeves (I'm not 100% positive there, but from all I could find, I seem to be right).

I believe H23's have iron sleeves.
