i'm still new to this stuff so please don't make fun.. From what i understood an h22 came with vtec witch will activate another rocker arm that will hold the intake valves open for a long period of time for more power after 4500 rpm..... is there anything other than this that gives the h22 more power? How would they be similar and different if someone put an h22 head on an h23 block? Again i'm still learning, thanx in advance and god bless.

 

look in the FAQ's and yes.. VTEC is basically the reason why H22 is faster than h23 out of the JDM happy meal. h23 with h22 VTEC head is a popular build.

anything past that, im clueless.
i would pull up all the numbers and reasons.. but theyre all in the FAQ and i'd feel like a dooshbag for regurgitating and getting any credit

High compression!!!! FTW

 

in stock form:
vtec
compression
gearing

however, just because the h22 is a more powerful motor, doesnt exactly mean that its better. the h23 is still a great motor.

reasons:
1. vtec
2. higher compression
3. popular (relatively easy to find and they are new)

putting an h22 head on an h23 is the same basic idea of a mini-me. in a mini-me, it raises compression to about 10.5:1, and the same would work for the h23 with h22 head i am guessing. also the vtec engagement of an h22 is ridicously loud and strong.

putting an h22 head on an h23 block actually drops the compression because the h23 combustion chamber is smaller than that of the h22.

 

I'd add no problems with bearings and cracking heads in H22... (at least much much less than in H23)

 

The best bet if your gonna do any type of H22 (be it just a head swap or complete USDM motor) is to swap in the shorter geared transmission. or you could invest the money in bolt-ons and keep pace with 5th gen h22s like me... save your pennies and go turbo maybe? no matter what i say, however, most of the informative peolple here will lead you to believe the H22 is far superior to the H23.

 

As an owner of both, I like them both for differnet reasons. The H23 has great low end torque and beats most H22's off the line, right up t 3rd gear, then the Top End of the H22 shines, which is why I like them.
The H23 is much better for city driving and zooming out into traffic from a stock. H22 is better for highway and passing cars and that sort of stuff.
As mentioned about, stock form, H22 has shorter gears and wider power band but H23 is a popular engine for people to boost.

Totally agree. I love my H23VTEC Frankenstein. Although the 2.3 crank doesn't rev as nicely, i still consider it to be the best of both worlds!

 

I can definitely agree.

I love my h22 on onramps and where I can let it loose up to 7k, but h23s are butter around town.

 

I have never driven the H22, but i know the H23A1 well. It is great for torque from low down and maintains strong mid range power. I can definately vouch for the reliability of the motor over time in daily driving use. AND it cruises powerfully on highways, Top Motor man

 

I have 2.3 vtec I blew head gasket on. I found a kit for sell on fb for way cheaper than I can get elsewhere. It’s for the h22 would this kit still work for my engine??

 

If you are talking "head gasket and up", and the H22 kit fits a USDM '97-01 Prelude H22A4... then yes, it will still work for a JDM H23A.

 

Yes, the H22 also has HIGHER compression than a H23. Stuff like that... Think B18c5 vs B18c1! It's an all-around better engine. H22's were built for performance and H23's were built for, essentially, ergonomics. H23's are like the engine found in older BMW 328i's.

 

Are you referring to the H23 DOHC non-VTEC engine in the US market or the H23A DOHC VTEC engine found in the JDM/EDM market ?

 

Oh, I'm referring to the Non-VTEC available in the US-market Prelude Si. I thought that's what he meant. I don't use JDM H22's in EG hatchbacks, ~ONLY~ H22A4's.
