H22 block and h23 head - Honda Prelude Forum

92lude4gen · 07-16-2009, 03:35 AM

Ok so i have a mad crazy deal to get a h22 90% comlete lower end its just missing a few pulley's and oil pan. it came out of i believe a 95 prelude the guy got side swipped so engine was un harmed and he used the head on his new prelude. but my question is if i can use the 2.2 lower end with the 2.3 non V-tec head. so if any one can help me asap i would be greatful. i have the oppertunity to get it on july 22, 2009 so the sooner i know the better. i do have the jdm h23a in my car now but the crank snapped in half and i need the car runnin soon so i dont get tagged with extra charges when i renew the plates so im tryin to get this done no later then the end of july

I'm sure its possible, it will be a 2.2 liter non vtec DOHC engine though .. less displacement on that block w/ that head = less power than a stock 2.3.

If you're stuck, ya go for it. Take your H23 head line it up with the H22 block and ensure all the oil and coolant orifices line up, ensure that the head gasket will work as well.

In my opinion, it'll be a lot of work that may not be worth it in the end, im sure you can find a used H23 anywhere for cheapy cheap.

I know that the head gaskets are different from the h23 vs h22. I've done h23 block with h22 head's and they make more power than a stock h22. I've never seen a h22 block with a h23 head, it just doesn't make sense why you would want it. Stick with the h22 head and you get to keep vtec!

ok i know ts been a while since i have been on but i ended up getting the 22 block and ran into some interesting problems when i stuck the 23 pistons in it was level with the deck at TDC and then when i did the h22 pistons just to see i had the same prob me and my team capitian are gonna re measure everything here really soon to see what is up and i know visually we can tell the rods on the 22 are shorter by about .5 to 1 inch... as far as the head matching up i have to do a bit of machining to match the coolent slots up but the rest works out perfectly. that and every time i have looked for the crank specs for the h22 and h23 i find only rod journals and main journals can you help me out if you have an idea on the both of them

Why waste the time and money only to lose some torque?

ok so i see everyone has their opoinion on how this is just wrong... but i have one good question how much of this have you truely researched for yourselves cause i have found interesting things such as the blocks them selves...let alone the rods, pistons and cranks... if you can give me answers on those and they are close to a match then maybe your worth talkin to... but im tire of you guys who have money and just send your **** into a shop and say you did most of the work. all i was tryin to get was a solid answer of if things would work or why im gettin these results... by the way for those who think Vtec's are good with turbos better hope you have money to rebuided it a lot cause your timing advances and retards with vtec and you cant have that with turbos... just FYI

well the reason i think is a waste of time and money to do that is for the simple fact that h23 bottom end is a lot better then the h22 bottom end, the h23 has more stroke and is close deck, therefore if u wanna go turbo you be able to handle more pounds of boost. And not to mention that you have to get the h23 waterpipe, thermostat housing, waterpump, timing belt (non-vtec has less teeth than vtec), headbolts, and different gaskets and also headers. I been doing some research on this because I'm doing the complete opposite jdm h23a with a type s h22 head, and you might even have to get a none-vtec lower crank gear but I'm not sure on that one.

Not all H22 blocks are open deck. Just so you don't have the wrong info.

oh thanks, what h22 blocks come close deck...???

the 22 block i have is a open deck with a block guard (ca we say coolin problems) and as far as gettin the block put back togeather will be easy case i have all the 23 parts from my destroyed block. thus meaning i can change what i need to... but it turns out im just gonna order in a nother jdm 23 so i can just build the heal out of it just waitin for my money train.... the block guard on the 22 is causin more probs then any thing and i am gettin tired of machining parts to get the results i want. and the torque issue in my build will be compensated with the turbo cause when racing i sta abouve 3.5k rpm's and i will only be losin low end torque... and bein an h seiries motor they are torquey from factor not gonna complain about torque loss
