H22A Swap - Dizzy Help

Hay all,

I could use a little help. :noidea: I am about to do an H22A swap in my ’92 Prelude this weekend and a have a question. My H23A1 has an external coil; my new JDM H22A has an internal coil. Is it best to stay with the JDM internal or is it possible to swap it and go with the external?

Thanks,
PCWiz

I have the “Ultimate H22A Swap Guide” by Nathan Morris that shows the wiring to convert from external to internal. I am just wondering if the internal coil is as good?

use all of the harness from the h23 it will all plug up, swap the fuel rail and use the h22 injectors, also use the h23 dizzy that is how my h22 was put in my car. then you have to run the two wires for the vtec sending unit to the ecu and Bamm you now have a h22

Is there an easy way to mount the h23 coil on the h22? the VTEC sending unit is right where the coil mounts on the h23.

So the external is the way to go?

Yes, plus what happens when it comes time to replace the distributor cap, your SOL unless you can find a shop that sells JDM caps. When I underwent that process, I just used the H23 distributor and have the external ignition coil sitting on top of the tranny. It hasn't moved an inch in 7k miles.

From what I have been reading on-line, the JDM motor with an internal coil uses the same cap and roter as a 2000 Civic Si or the 90-93 EX dizzy.

If the dizzy's interals and mount are compatable, I would like to go with the external one.

It is a 100% swap down to the mounting bolts.

I agree from the most part. Use the h23 dizzy you already have in your car. Put H22 plus wires on it keep it external coil. The fuelrail already in the car WILL work just switch the injectors and your golden .

The fuel rail will not work if it is a JDM H22A because the fuel line is on the wrong side, use the H23 fuel rail with the H22 injectors.

Well it has taken me all three days just to get the H23 out. Nasty... but its out now. I will go ahead and use the external dizzy. I have a lot of pics. I'll try to get some posted as soon as i am done. They say this swap should only take 20 hours, NOT. I should have the H22 in by the end of next week, I hope.

Man, 5 hrs thats pretty quick...I mean, it's a swp not a replacement. Get a buddy to come over and take everything acces. wise off the front of the motor pull the rad. out and it should go in fairly easily and be bolted up in about 20 minutes...then the rest is putting everything back on but it's easier this way. Make sure you put the harness on the motor BEFORE you put it in the car. Don't forget ALL your fluids!!!

Looking at the pictures looks really good...are those the Samco hoses on the radiator? And just a tip, make sure you clean the header off really good if it's SS before you fire it up, try to get all the finger prints and crap off of it...makes it prettier!!

I have had a light weight pulley on mine for years with no problems...I run the Unorthodox set of pulleys on my H22. I'm sure this is debatable but thought I would throw it out there...
