4WS and JDM H22 compatibility? - Honda Prelude Forum

Is the JDM H22 VTEC engine compatible with the 4WS system in the 4-Gen Preludes? I'm close to getting a car, and I'm considering a 4-Gen.

ur gonna need a JDM ECU off a 4WS to get it to work. else ur rear tires will just... well, keep straight

Actually a regular VTEC ECU will work. My car was originally a 4WS prelude but I swapped in a VTEC engine. The 4WS computer doesn't interact at all with the 4WS.

So a 4WS would retain 4WS if a JDM engine were swapped in?

Do you mean "VTEC Computer"?

oye..... people people.... you do not... and i cannot stress this enough.... do not have to have a VTEC 4WS ecu. the 4ws has a seperate computer that does not interact with the main ecu. You just need any old h22a with matching ecu. No problems whatsoever....

my car is a living, breathing model of it.

That's what I meant.

I tried to say that the ECU and 4WS computer were seperate.

Isn't the 4WS ECU in the back.

I remember when 93si4ws found this out awhile back. It took him so long

Being as I have a 93 Si 4WS, this is verrrry cool news.

Now I have to wait for my H23 with 72k miles to die

Could take a while from what I've read about the strength of this engine...

this is a topic i still don't understand.... why do you want to go vtec? cause it's stronger? i guess you can say that... 30 hp stronger, but then again, it's literally $3000 just to swap in a full h22a (clutch, tune-up, and labor added). While with the h23a, you can easily go turbo and beat any damn vtec ass. While if you go h22a then turbo that's nearly $6k you're looking at. You can cut that bill in half or even better, build the h23a then go turbo for the same price. Trust me, a h22a swap into a prelude isn't much, people really don't give a **** that you have a JDM h22a just because the prelude already came with the h22a from the factory. It's not like a ek/eg civic with a b18c or h22a where there's alot of hype (show/race wise).

think about it....

If i didn't blow my h23a, i woulda just gone turbo.

Ditto.

Honestly, I think it's a preference. So far, I get enough $hit&giggles driving my friend's JDM H22, and stock '01 Base. The thrill of dependable all motor power.

I have yet to drive a turbocharged car (Nobody wants to hand me the keys) and I've been in a WRX. Turbos are a big kick in the ass, just like VTEC is...and besides, a JDM H22 is easier to maintain than an H23 Turbo.

Absolut: Would you agree with this?

I do, to a point.

If your h23 works fine, leave it be. If you have an extra $3k laying around, then go turbo, just remember that your engine life is going to be shorter.

I would have stayed with my h23 had I not blown it, that $3k I spent would sure come in handy right about now.

And an H22 in a 4WS is a big deal...
How many do you know of vs. regular steering VTEC's?
