I have a 93 lude with an h23a motor, however i think someone has slapped a vtec head on it. Ive looked on the head for possible vin numbers or some kind of number code, but the ones ive found make no sense to me. the reason i ask is, i need a coil, but i dont know what kind to buy, one for an h23, or one for an h22 (if that is indeed what type of head is on my car). Ive posted some pictures of the block and head and the numbers that are on them. Plz Plz someone tell me what head i have so i can get an idea of which coil to order. And no, this is not an attempt to ***** out my car.

VTEC valve covers don't fit on non-vtec heads. Also check out the VTEC solenoid behind the dizzy. You can also tell by combaring the bolt patterns of the header and i/m to a regular H23.

 

thats a swapped motor. notice the block doesnt have an a1.

 

ok so now i know its for sure a v-tec head, now the matter of wether its an h22 head or not. Like i said earlier, i need a coil, but im unsure of which kind to buy. the car has the external coil. Im new to the tuner business, and know very little so any help is greatly appreciated. thanks

 

does the a1 indicate a v-tec motor? or does it indicate a non-vtec motor?

 

This might have some useful information:

but try to ignore the bickering ><;

 

you need a coil for a 97 to 2000 prelude

 

ummmm.....ok. so do i need an h22 coil or h23?

 

o and btw k-lit. that forum was somewhat helpful. i got a little bit of info from it, in between the rants. But heres what throws me off, if all the h23a's are suposedly non-vtec, then how does mine have a vtec head on it? especially considering that v-tec heads wont fit non-vtec motors. I think someone on there was mis-informed

 

h23 bottom end (block) can be mated with the h22 head (vtec head).

I can't see your vtec solenoid though from your pic. Could you take a pick of your motor from right above the valve cover but zoomed out a bit so you can see entire engine bay. Vtec solenoid sits around behind your dizzy. I don't see a power steering pump either lol.

I also believe vtec valve cover will not fit an h23 head, so you do have an h22 head. Weather or not it has a vtec coil, p13 ecu, and is wired for vtec is another story.

Try to post that pic and some one here will let you know.

 

yea no power steering on this thing, which isnt too bad really lol. the pics are as good as i could get as it is getting dark.




i think the ecu in the car may have been changed because the carpet on the passenger side floorboard is loose, and the wiring is all crazy. are there any marks or nu,bers i can look for on my ecu to tell if its a p13 or not?

 

Looks like a VTEC solenoid to me

 

good deal. ok so now the root of all that is evil with my car lol. since i have a h22 head on an h23 block, do i need a h23 coil or an h22 coil?

 

According to hondaautomotiveparts.com, the ignition coil is exactly the same on an H23A1 and the H22A1, P/N 94656.

H23A1

H22A1

Based on that, I'm of the opinion that it doesn't matter.

I run an H22A (JDM motor) with that external coil, no problems.

 

You have a JDM H23A, which comes mated to an auto tranny in the JDM Accord SiR station - Aerodeck. Its basically an H23, mated to an H22 head.

The distributor looks like its OBD1, judging by the two plug type (OBD1 comes with 1 plug), so it has been swapped, which means its prolly from a H22.......this taken into consideration, you would need an H22 INTERNAL coil.

You could also swap out the dizzy cap and run an external coil......MSD is popular and sells the complete setup..

You ECu is also OBD1 and is or the stock P13 which would drive the engine OEM-wise, or the very broad possibilities of chipped ECU's

(edit: just saw yours is an auto, so i bet its the JDM auto P13 ECU............the wild wiring at the ECU might explain the needed splicing - what year is the cchassis?)

The label with numbers, look for the middle denomination, on the ECU should tell you what is is/was.

 

they both look the same to me. my motor is an A not an A1, but i dont think that should cause any problems. Here's what im looking to buy.

http://cgi.ebay.com/ebaymotors...ZWDVW

i can get this for roughly the same price as a stock one. deal or no deal?

 

well mervin thanks for the info. but as it is now the car has an external coil, which leads me to believe theyve scrapped the old internal coil when they bought the car maybe.. which is why im looking to buy the setup i linked in my last post, if that will work without any problems then great. if not, i need to know cause im stranded with no vehicle. chassis is a 93 by the way

 

the setup in the ebay link will work....nice red color is good for 10hp too!...
lol!

no prob, were here to help, good luck with the car!

 

thanks man. and thanks to everyone who posted for that matter. but just to re-itterate. the h23 coil setup im looking at will work right, with no problems?

 

Engine: H23A DOHC VTEC from Accord SiR

Coil: Internal, replace with H22 97-01 (i dont see an external coil, its usually mounted next to the vtak solenoid)

ECU: OBD II (all 1996+ motors were OBDII which is another reason i think it is internal coil.)

the coil was there i had just taken it off prior to the pictures that were taken. and yes it was external.

 

If it has an external coil like you say then you need the ignition coil from an OBD1 1992-1995 Prelude with either the H23 2.3 liter nonVTEC engine or the H22 2.2 liter VTEC engine.

Honda part number: 30520-PT3-A02



BTW that's a neat engine you have there. lots of torque and beefy block with 55mm mains. Uncommon and has a lot of potential. Too bad you have an auto though. Good luck.

Listen to Pirates info, as it is correct! That is a cool and rare engine, the H23A was in the accord si-r wagons, only came with automatics, and usually runs twice the cost of an h22 if you can even find it! I would also suggest that after you find out what ecu is running it, look into getting it tuned, and give us some dyno numbers as to what kind of power that motor actually makes! As Pirate said, it should be higher torque and horsepower than an h22, and has the sturdy mains. And don't paint that blue valve cover, thats the color those motors had, and its much less common.

 

.......It is a 93 prelude so it could have had the external coil already there and was just swapped on the H23A. Look at the tensioner (it looks like the belt cover has been untouched), If its still got a an auto tensioner (if it hasn't been swapped out too) it's definetly the 97+ H23A factory VTEC you got in there. Congrats, you got yourself a sweet motor there.

 

ok cool forget what i said then.

+1 to pirates info
and +1 for a nice motor.
