hey guys.. i have a prelude but in the prelude section every one only knows H series... well my prelude has a F22A1 motor.. (u know the type S prelude) any way it has around 150 k on it and hasent been under the best care either.. dose any one know any info about the (JDM DOHC VTEC) f22b1 i belive it is.. or if not but you know what F series motor im talking about (not H) then please answer a few ?s for me.. my AIM screen name is rollthadice21

thanks alot

 

The f22b is a great motor for boost.

 

*sigh*

If you are asking about the DOHC f22, then its the JDM F22B DOHC, nothing at the end, its JDM.(from jdm preludes)

it is rated at 160hp and I think 153ft/tq, has 9.2:1 cr, and pretty much an f22 blcok with h23 head. It's very similar to an H23.

Differences in the H23 nonVtec are:
h23 has 9.8:1 cr
h23 about 5ft/tq more
h23 sleeves are made out of the same material as the h22, thus not very optimal for boost.


In you post, you said JDM DOHC VTEC, well, there is NO F series engine that matches that description. All H series do though.

F22B1 SOHC VTEC, which comes in the 5th gen accords(EX models, maybe SE, i duno)
-F22B2 is SOHC nonVtec(LX 5th gens)
-F22A SOHC nonVTEC(4th gen JDM accords)
-F22A1 nonVtec(4th gen USDM LX accord and prelude type S)
-F22A4 nonVtec(4th gen SE accords)
-F22A6 nonVtec(4th gen EX accords)

You are so lucky I'm bored. You could have found all this out with >5 minutes of searching.
