f22b jdm or h23 dohc

[travis2k16]

ok im not sure but if i were to get the h23 non v-tec dohc motor from a usdm prelude would i have to change my ecu and would there be any other changes and also same question re guarding the f22b

The H23 has a knock sensor you would have to run to your ecu, I don't know about the F22b.

whichever you can source first for the best price...

the H23 does have a knock sensor you have to take care of if you run a p14(H23 ecu)... personally, i own a JDM F22B and i'm running it with the stock pt6(F22A ecu) and it's been running flawlessly, don't know if the same can be done with an H23, but if so, you could get away with running the stock pt6 until you can maybe get a chance to run a chipped p06 or something of the same sort

ps. look at the JDM F22B as the "first option" and the H23 as "backup"...

Call them and ask they usually have some in stock. If that fails tigerjapanese.com.

Im kinda in the same boat. the H23 and the f22B are on my list along with f20a1 or another f22a....

Im just looking for direct replacement though..but of the the 4, it seems that the f22b and the h23 are the top choices. Although that f20a isnt far behind the h23..



:OT: thanks for the TJ link Nelson. Found damn good prices on some of the ones ive been looking for.

Aside from the addition of some K series motors, that page hasn't changed in YEARS. They're real people. They can get you anything you want.

i personally like the f22b because it comes with a cooler valve cover...plus the headgasket is the same as the f22a BUT you'll have to buy a headgasket set from a h23 in terms of valve stem seals, cam seals and the such.
