Has anyone ever known or heard of anyone throwing the H23 bottom end to to the H22 head? I know it isnt that crazy of an ordeal, but does it actually make power? I know of one person only that has done it, and he claims alot of power from it, but he lies..........

 

not worth it..

same as h22...

 

its like a ls vtec of a h series!!

 

yeah, but without the payoffs!

The payoff could be very good. more hp and lot more tq... if you have it done right.. Yes its like a LS/VTEC for a H series. but only better.. b18c stroke 87mm.... b18b1 stroke 89mm.... Thats only about 2mm increase in stroke and they still run hard... now H22A stroke is 90.7mm....... H23A stroke 95mm.... thats 4.3mm more mm of stroke.. So basically If you want you can gain alot more displacement by going h23. but you need to address the pistons ofcourse.. If you want, We can perform this setup successfully...

Max-

 

I've heard this before. What issues do you have to address regarding the pistons/crank? Just curious and what would be the best way to get the h23 combo to rev like a h22 motor without breaking anything?

 

get an H23VTEC from a factory 99 Accord SIR-T they came factory with a h23 block and h22a head. in those years.. unfortuneatly it only came with an automatic tranny but mount your 5 sped.. any engine importer can get you one.. and will be hella lot cheaper than a conversion.. and allready come with 11.0 cr spec s pistons.

Its not worth it stick with the h22 block same thing

 

h23 vtec did not come int eh accord sirt, those came with f20b. the h23vtec came in the accord sportier wagons, and only in automatic. the difference in those is the have a forged crank. the standard usdm h23 crank is the same thats used in the f22's, a cast piece of **** that will break.

 

It's is not the same thing h23 and h22 have different crank and rods. match the h23crank witht he rods and h22 pistons you would be very surprised. h23 has bigger stroke more torque and the head and camms give you best of both worlds. My buddy has hatch 23crank rods type. s pistons and stockhead with type s cams and put down 207whp with mixture of stock parts

ive been told by a couple of well known engine builders and they agree that the h23 crank is a forged peice like the h22.Regardless if its from a f22 or not.

 

AKS ME ASK me! ......

the answer.... not worth the tunning time of it. If I had to pic building a H23vtec or just building my F22vtec I would stick with the F22 vtec!

MY boy has one in his 5th gen accord. Took him forever to do it and it finally ran right. It was tunned with and afc using a OBD1 GSR ecu. only made like 188whp with 153tq (i think) somthing around that....Don't aske about what it ran in a heavy asssss 5th gen accord.... (do the math 188whp in a 2900-3100lbs car)

I know that if he had a chance to do it all over agian he would of gone F22vtec turbo.
