know anyone that ships low mileage h23 engines? i'd take boost over vtec anyday.

[Prelewd]

just wondering what you have to do to the h23 wiring harness when swapping it for an h22..

I just did the swap from a h23a (same as yours) to the h22a (vtec) in my 93 prelude. The h22a will run you about 2700 shipped and will include a new tranny and ecu. everything you need to make the complete swap. The JDM h22a will fit any 92-96 prelude, and will produce over 200hp ( 40 more than the h23a). I am suposed to get my car back tomorrow or by monday, and will post the news.
Hope i could have been a help

Will you keep it standard or boost it?
If you are thinking on boost just spend some money on the original engine and put 12psi down its throat it should be good for 300hp.
if you just want a quick fix then both gen 4 and gen 5 h22a's fit straight in but bye bye to the tranny plus the ecu. By the way who wants an auto anyhow?
I just saw a h22a in a 92 integra it goes well.

all the best :flash:

he seems to think 12 psi will give u 300hp. i wish.....

ok ok, sounds better then. i jus thought u meant putting the turbo on at 12 psi was gonna put u up to 300hp. thats why i found it pretty tough to believe, but if ur goin about it like u say, then good luck man...keep me updated on ur project.

It was probably my earlier statment that 12psi should be good for 300hp and with a few mods. I was thinking if a 6-8psi (avo) kit gives some 60% increase in hp, 160hp + (60%) 96hp= 256hp. And that another 4-6psi will give you another 40hp. Of course you would tuffen the engine and probably run lower compression ratio. As the difference in compression between the H23a and the H22a is only 0.2 C/R (9.8 and 10).
At 6-7psi my lude makes 50% more power at the wheels.

Anyway peace :flash:

140hp from a turbo kit? which one, cuz IF that were tru...hook me up w/ one...most i see on engines (without HUGE money into them) add only around 70-90hp tops at 12psi.

If you do it right, you can just stick on a turbo and get 300hp.

Holy shit. 379hp to the wheels? That's almost 450hp to the flywheel. Impressive, I wonder what they did to it.

[mjline99]

i would like to kno what would be best to do turbo h23 or h22 all motor and what would be the fastest and be the cheapest. i would also like to kno what is exactly all in rebuilting an engine(meaning what would i have to do to be able to turbo a h23).
