H22/H23 block

gunnmen01 · #1 03-10-2003, 07:42 AM

My boss is looking to build a motor for his prelude, its a H23...but can he use the H22 block? He can get a good deal on the H22 block...just wondering if there is any difference? Probaly just the oil passage for the vtec soleniod.....If any one know, i allready posted in the prelude section, but as we all know things get answered faster here.....thanx

Well he can use the h22 head on his h23 block. I think its pointless to go the other way around cause it doesn't do anything. Tell him to do h23 v-tec set up. THe fastest all motor car has that set up

I meant he's looking for a block to build up, cant find a h23 block cheap but he can find a cheap h22 block.....if you can do the 22 head on a 23 block you should be able to do a 22 block and a 23 head.....right?

why would you want a H23 head on a H22 bottom.

gunnmen01 · #5 03-10-2003, 12:04 PM

gee maybe cuz he can get the h22 block really cheap and cant find a 23 block that cheap...

Well what ecu hes gonna use? Its pretty pointless either way. Just tell him to go full h22.

well if hes going to go h22 bottom then he might as well get the h22 vtec head, it'd be stupid to use an h23 head on the h22 block. it'd be like putting a ls head on a gsr bottom

ok let me make this real simple...and please read it so you know what im talking about.
He wants to build this motor, we cant find a cheap h22 block, we cant find a cheap h23 block. will the h23 head fit on a h22 block....no other variations no different ecus...just a simple yes or no will the head fit on the block....we have the h23 motor and can get the h22 block cheap

lol

i've never seen anybody try to put a h23 head on a h22 bottom. theres no point, so i dont know if it can be done or not.

one thing that just came to mind. if you have the whole h23 engine, why dont you just build that, if you put a h23 head on a h22 block i think you might even lose power since your losing that .1 liter you had with the head on the h23.

So he can drive the car while building the motor...

Whats so hard to figure out? will it fit yes or no?

civickiller · #14 03-10-2003, 01:33 PM

actually ive seen a ls head on a b16 bottom end. some shop over here sold it to some kid and they never told him it had an ls head, so the kid thought he ahd a vtec head

gunmen im not confused about your question, im just confused on why you would put a 23 head on a h22 block, you might even lose power, cauase your losing that .1 litter.
