All this talk of h22 this and h23 that, just wondering what these mean..h22 is the 2.2L? and h23 2.3L?? Plus you can have a 2.2L Si?? thought all Si's were the 2.3L..Another stupid question: Can a Vtec prelude be non-Si??

 

h22 and h23 are the engine codes...they are stamped on the block.

Satan, of course is right. As fars as the 2.2 si? it doesn't exsist, unless there was a swap of course. There is the h22a1- american 4th gen prelude si vtec. H22a- jdm 4th gen prelude sir vtec. h23a1 is the american si nonvtec in a fourth gen. All of these are DOHC's. The F22a1 is the 2.2 SOHC found in the american S model preludes. So the only way for a non-vtec prelude to be vtec is if there was a swap done to it like mine/

Umm....I'm pretty sure the F22B has a few different versions, there's both SOHC and DOHC...I also think one of them was VTEC, but don't quote me on it, I really can't remember. But I know the Si came with the 160hp F22B, the equivalent of the H23...not sure on it's size though...I'm going to check that now...

*edit* brain far...yea, F22...2.2l..yeh...hehe...good job, lol.

 

The only F22B is JDM DOHC.

 

you're thinking of the F22B1 etc...the accord motors SOHC VTEC and stuff. THe F22B (no number) is the JDM DOHC. It's an H23a with a smaller bore. Same stroke and rods etc.
