6th gen H22 SWAP INFO.
Here's a summary of all the information I have on this swap since a lot of people have been inquiring about it.
MOTOR MOUNTS:
ALL accord mounts from the 6th gen will be used. You will need the accord rear, front (can be subsituted for h22a front mount also), MANUAL not automatic tranny mount, and accord driver side mount (slight modification will be needed)
The MANUAL tranny mount, front, and rear will be simple bolt-ons.
The DRIVER SIDE mount has to be modified to fit (see picture 1 below). Simpliest way to do this is to loosely bolt the other three mounts in place and draw out a template for the mount on a piece of cardboard, then cut it out and see if it fits the mount, after that mark the holes and trace it to a peice of steel or something sturdy, cut it out and bolt it in.
NOTE: There is very little clearance between the firewall and intake manifold, you will find that it is easier to install the motor around if the secondary butterflies are removed.
---------
A/C:
A/C from the 6th gen accord will bolt be use. Basically a bolt on.
---------
POWERSTEERING:
Several options with this:
OPTION 1: I have heard some said they used a h22a4 (97+ H22 motor) powersteering bracket and a little force to make the accord powersteering pump bolt up to it.
OPTION 2: Make a custom powersteering line that connects the prelude powersteering line head to the accord line to fit it to the inlet of the accord (see picture 2)
---------
WIRING:
EGR: Swap the egr from the F23 onto the H22.
Manual cars:
Just find out where each plug goes and plug it in. Some wires will have to be extended. Should be the same as a 5th gen.
Automatic cars:
You will need to rewire the car to use the prelude vss, just splice the prelude vss harness onto the accord harness and plug it up to the prelude vss. Then tap the output wire from the ecu to the tach into the input wire that goes into the ecu. This allows your speedometer to work properly.
Converting to manual:
You will need to rewire for neutral safety and reverse as well as rewiring the VSS like above.
I also recommend that you make a custom bracket to bolt the top of you clutch pedal to for added strength, I broke 2 clutch pedal brackets from regular driving from not having the bracket. Easiest way to do this is take apart your dash and weld on a steel bar to the firewall that reaches over to the metal frame tubing underneath the dash. Then bolt the top of the pedal bracket to that. This will make your clutch pedal be able to resist the pressure better if you shift with and iron foot like I do.
------
AXLES:
ALL Accord Axles will be used including halfshaft.
------
ECU:
OPTION 1: Keep obd2 by finding a 96 h22a ecu. This ecu has no immobilizer in it so its basically plug and play.
OPTION 2: Convert to obd1 by buying a conversion harness (same as the 00 gsr) then plug up a p13, p28, or any other compatible ecu.
------
This is a fairly basic swap. I did a lot of research on this before my swap was done and the info was very hard to attain since this subject is fairly new. I gave all the info to my friends at STREET DRIVEN PERFORMANCE in Baton Rouge, Louisiana and they did the swap for me. Basically this a summary of what they had to do. I have also added in other things I learned while they did my swap into the details above. I did not do the swap myself so i have retyped the details to the best of my knowledge. If anyone else that did the swap themselves have anything to add or can correct any mistake that i have made in the details, please feel free to do so.

Oh yea, here's probably the best advice I can give you...
Take your time and have patience cause if you get pisted it will only take longer to do the swap.

Re: (greenli0n24)
here is a pic of (option 1) on the power steering line.
this is 97 up prelude bracket w/ 98 up accord pump w/ very little modification (basicly you bend it a little)

Re: (greenli0n24)
yea save the money from the install and put it towards something good, like rebuilding the motor before you install it, a lot of people buy motors and just drop it in but i didnt want to risk that since i dont really know the condition of the motor before i bought it so i went ahead and had the motor rebuilt before having it installed, cost is kinda hefty though cause parts for the h22 like bearings and stuff aren't cheap, but you get a better peace of mind.

i think you meant thats a picture of option 1. option 2 is a custom line that will let you use the prelude powersteering pump

Re: 6th gen H22 SWAP INFO. (areyouasian)
This is all great info but I will add/clarify a couple tings (As I/we have personaly done this swap several times).
#1 - In regards to the top driver mount, there is an easier way. Re-use the Accord "arm" as above, but rather than making a bracket, simply drill a hole through the H22 engine mount bracket (the part that bolts to the block) and insert a long bolt (a suspension bolt is the perfect length) and put a nut on the bottom. Tha Accord 'arm' acts as a template for the drill bit so the hole is gauranateed to line up perfect. Once installed this way, it will hold without any problems.
#2 - If you are doing this conversion in an automatic, be warned - The wiring is much harder than stated above. We installed a 97 JDM H22A Triptronic Automatic package into a 99 Accord EX, and we encountered this problem:
The Accord uses an integrated ECU and TCM. They are a single unit. The Prelude uses a seperate ECU and TCM. The plugs at the ECU/TCM end of the engine wire harness are completely wrong. You will have to (as we did) re-pin *every* single wire to allow the H22A ECU & TCM to function properly.
I will say, It's quite a feeling of achievement when it fires right up and has no "codes". Triptronic is fun in an Accord, also.
#3 - Adding "triptronic" to any Automatic car is very easy BTW. It actually has nothing to do with the physical transmission. You only need a TCM that supports it, and the shifter control box. It's just three little wires between them, that's it . . .
BTW: ECU= Engine Control Unit, TCM= Transmission Control Unit
Hopefully this info is useful to someone . . .
Thanks

Re: 6th gen H22 SWAP INFO. (areyouasian)
Good write-up Peter.
I got some issues regarding the resistor box. Could you help me out and let me know where the wires go. I have searched and asked questions, but I haven't gotten any good results.
Thanks.

Re: 6th gen H22 SWAP INFO. (areyouasian)
has anyone ever made poly solid mounts for the H in 98 and up. i am about to poly urethane them myself. i have been searching. i also need to find an ob2 engine harness for an h22. i need to convert back to obd2 because of emissions. my car was an automatic converted to stick [IMG][/IMG]

Hi Guys,I'm new member in this forum I have big project for my car and I need help from you guys. I have 6th gen accord 98 v6 auto and I want to swap to manual use acura cl-s trans 6 speed and I have some question for you guys.
1.If I have to changed the ECU accord use the ECU cl-s I just modified the wiring harness only to make sure can plug to the ECU from cl-s,Thats right or no? ( thats mean I don't have to swicth around the wire just modified the wiring harness)
2.Which one wire I have to changed for the trans?
3.Which one better I use the shift lever from cl-s or I use one from 6th gen accord manual trans?
4.Can I use the breke pedal,the clutch pedal and the clutch master cylinder with the pipe line until the cylinder slave?
5.How about the mount trans,do I have to modified alot to get set?
6.Do I have to changed the motor starter from cl-s?
7. Can I use the old axle left and right or use from cl-s one?
8.can I use the old bolt for flywheel?
I think thats all question I have in my head right now and I really hope you guys can help me out about this.Before and after I would say Thank you very much for your help.
My regards
Conge

Re: 6th gen H22 SWAP INFO.
can some one give me a website where i can purchase the h22 swap wit all accessories for a good price. cuz ebay has the h22 ENGINE COMES WITH THE FOLLOWING:
* ENGINE
* WIRING
* ECU AT
* TRANNY AT
* COMPLETE INTAKE MANIFOLD
* DISTRIBUTOR
* ALTERNATOR
* AC COMPRESSOR
* POWER STEERING
* ALL BRACKETS AND SENSors
the swap is from 92-95 does that matter or would it still work?

Re: 6th gen H22 SWAP INFO.
you can find most of the stuff you will need on ebay. Different sites will provide you with different parts depending on what you need. If you need an entire transmission setup, then you will have to get h22 with transmission. The one you listed above is for "AT" = automatic transmission. Make sure that's what you want. Either way, you will usually still have to buy some hoses, belts, and new parts to replace the old motor such as water pump, spark plugs, etc. No single site will provide you with absolutely everything you need. Check out hmotorsonline and google search for some different sites that sell. jhotimports is good and usually has prices better than others.

Re: 6th gen H22 SWAP INFO.
I have an 01 Accord (6th gen) and am doing an h22 swap, i have the motor trans, wiring harness and ecm for the h22, do i need to re wire anything to make the h22 harness capatable with the accord body wiring harness? or did you use the accord wiring harness on the h22?

Re: 6th gen H22 SWAP INFO.
kinda gona kick start this one again.
good write up as this info is very hard to come by even now.for the engine mount iwe just used the prelude mount and modified it slightly..better than spending£££ on a costom kit .everything is fine worked for me but could sumone be more specific on the wiring side of things.i have the m/t h22a(jdm) but cant figure out what sensors need to be changed/cut/added any help would be good. iv got everything i need including OBD2b-OBD1 conversion harness so its just the wiring on the engine block side of things
the swap is taking a F18b2 from a 6th gen accord (ukdm) and putting a 1992 (jdm)h22a from a BB1 prelude.
should also note that the h22a came with the skunk2 pro series intake mani so the egr valve isnt needed
