H22a vs H23
I've been reading through posts, etc. and see a lot about the H22a and H23. I'm working on some research and stuff and was just wondering what some of the main differences are. I hadn't heard of an H23 until coming on here so maybe u guys can help me out a bit. Just curious, thanks.

Re: H22a vs H23 (1sexySH99)
they are the same blocks.
H23 is a 2.3L DOHC non-VTEC motor. 160HP. 9.8:1 compression. The extra displacement is from a longer stroke.
the H22 is a 2.2L DOHC VTEC motor. 190HP. 10:1 compression. The shorter stroke allows for less stress at higher RPM.
The explanation behind the differences in the valvetrain operation, and the internal geometry could fill pages. A solid understanding of how engines work will go a long way.
The H23 was found in 1992-1996 prelude SI, SI-4WS & SE models, mated to both automatic & manual transmissions.

Yup.
The H23 stops making power at 5500 rpms. That's where the H22 shines, after 5000 rpms
The H23 is a good motor for daily driving. However, if you are looking for power and fun to drive, that's why they developed the H22.
I've driven both on the track and there is a night and day difference. Where the H23 used to buzz around the turns....the H22 now makes power. 4th gear is a night and day difference too.

Here is 95PreludeSi's before and after swap he had an H23, now he's got a JDM H22A:
Of course my H23 hybrid makes almost as much torque ah his H22 makes power.

The entire H23 is a crappy motor, but if you just take the H23 block/crank and put it on an H22 you get an entirely different story. This would be the ideal setup for a turbo due to the added displacement, you'll make more torque and more air will go into the engine.
