Non VTEC conversion

Hey guys, I have an 92 lude with h23a1 engine, and ive been doing some reading that you can throw a vtec head on this block? i realize ill need all the other goodies that come with adding a vtec to a non vtex car, but is possible to get a vtec head for this engine and convert it? If so that would save me a lot of money and labor compared to swapping entire engines out, lol, not quite ready for that road trip yet

Re: Non VTEC conversion

It's possible.

It came as an option in some very rare cars. The engine's code is H23A. Not H23A1 like yours probably has. It originally came with a blue valve cover.

Do some researching and you will find your answers.

Is it possible? Yes!
Is it hard? Depends on your level of engine/Honda knowledge. It definitely isn't no cold air intake install. You will need a bunch of parts along with a VTEC compatible ECU.

Best of luck.

Re: Non VTEC conversion

Many people refer to it as the H22/H23 "Frankenstein Build". If you search around with that phrase you'll probably find some good threads on it.

Re: Non VTEC conversion

The crank/rod combo between the h23 and h22 have different strokes and TDC durations. You will quickly run into reliability issues if you use the stock bottom end with a VTEC head.

Re: Non VTEC conversion

well thats why i posted here, i don't ever do anything like this before tons and tons of research. this just happens to be one of my starting points. do you guys think it would just be easier to swap out for a H22a?

also, a side question. today i found this extremely tiny switch above my hood release hidden up in there... anybody know what it is? what it does? first time ive seen this and cant find any info with google or even a chilton manual or anything

also, a side question. today i found this extremely tiny switch above my hood release hidden up in there... anybody know what it is? what it does? first time ive seen this and cant find any info with google or even a chilton manual or anything

I believe it is for the Honda security system, my 95 SRV also had this. Try this, remove the DRIVERS seat and see if there is a little security module there under the seat. I believe when working correctly it acts either as a kill switch, or panic button. Anyway, I ripped out the security system and re-wired the button as a horn since I have a removable steering wheel.

Re: Non VTEC conversion

Yea. It's not a direct bolt down and go...
I'm currently doing a Frankenstein engine, and have headaches from studying threads, parts, etc.... You can't just jump into this. You need to plan, I suggest doing what I'm doing, get a spare block, spare head, and build on the side

well that was one of my plans. i knew it wouldnt be as easy as just dropping on a new head, i do understand that much, i was just curious about the end result and if anybody had ran into complications from doing so. but ill probably just get myself an H22a and blueprint it on the side till im ready to drop it in. but that down the road a bit
