Ok I did this for the newbies and some of us oldies as well. It is a checklist of the parts need to do the H22 basic swap. This is for the Si models only. The S models will need more work to make this swap work.

Edit: 4-1-2009
I wanted to clarify some things to those who are not aware of the weight differences between three motors since we now have a little support for the B series mounts.















Engine weights with 5 speed trannys on a palet:

1. B20a -

   B20 at aprox 410 lbs

   auto trany installed and on a pallet.

2. H22a -

   H22a at aprox 445lbs 5 speed trany installed on a pallet.

3. B18 -
   

   B18 in his

   civic so i weighed the b18 at aprox 380 lb 5 speed tranny installed and sitting on a pallet on the scales.

*Note: The above information was taken from a member who weight out all three motors in this thread: http://www.preludepower.com/forums/s...=260249&page=3




Here are writeups that will help you on your journey with the H22 swap:















These are some original swaps, so some information is outdated, but they will help you to see what is involved.

• H22 Write up
• Long H22 Swap Write-up
• Another H22 write up

And here is a review regarding the AZ Race swap kit, and some usefull tips when installing.

• AZ Race H22 3g Mounts Review

Parts Needed:

1. AZ Race Mounts - sold through me(1FunRyd - contact: onefunrydperformance@q.com)




2. H22 engine, tranny, engine harness, and ecu. (Deathwish thank you for posting up your swap pics for the intial AZ Race review)



3. Your stock engine harness and the H22 engine harness to be sent to www.rywire.com ask for Ryan or if you can do it yourself then that just saves you some money. The 88-89 ludes who do this swap will need the OBD1 conversion harness that rywire.com can provide for a fee.
The 90-91 ludes just plug right into the P13(H22 stock) ECU. **Edit**: 90 2.0S/90-91 2.0Si models are still OBD0 and will require you to upgrade to an OBD1 format. 90-91 Si models are OBD1.



Update Edit: Igniter wiring

originally posted by 91Owner -
hey sean
cinci filled me in on what i think could be added to the swap thread.
first my car is 91 auto b20a5 with the igniter on the shock tower. the h22a has the igniter in the distributor .i used a msd coil and connected to the stock coil wires inside the cap. not knowing i was connecting to the internal igniter started my car with both connected and it runs very ruff.
so maybe should be on the post for newcomers to only use one and disconnect the other.
when cinci mentioned this today was the first time i've read that anywhere. to a newbe like i was that is key info that would make the life of a first time swapper much easyer

4. The 92-96 Prelude shifter assenbly and linkage for proper shifting.
Other Honda Models for the shift assembly:
Shifter boxes and cables.... You need either 92-96 Prelude shifter box AND cables, 90-96 Accord shifter box AND cables or 97-2001 Prelude shifter box and Cables.

Here is another thread that will show the typical issues when swapping shift linkage and which ones to use:

Pimpstecy ***





5. The 90-91 Preludes have an electronic VSS speed sensor so no need to do anything except plug it in. **The 88-89 Preludes have to take off the electroninc part of the VSS on the H22 tranny and use the clip that secures the speedometer cable to the 88-89 VSS. Here is picture of the 90-91 VSS which is the same as the H22 VSS **Note for the 88-89 luders I would recommend keeping the rubber boot that comes stock on your old VSS so you can swap it on to the H22 VSS:









Update 8-30-2009: Here is how the 88-89 swapped ludes need to secure the Speedo cable to make your speedometer work. This does not solve the signal need to make the VTEC solenoid kick on, but it will solve the speedometer issue. For those who will be going P28 and have the VTEC programmed by RPM then you will not have to worry about not getting VTEC.
*I am going to try and have a special bracket made and sell it so all 88-89 H22 swappers can still have their speedometers working.


















6. A modified Radius Rod for lowered ludes so the radius rod will clear the crank pulley. Or you can swap the crank pulley out for an aftermarket aluminum one which is smaller.
Edit 4-16-09: AZ Race is producing a traction bar that will clear the crank pulley and clear the AC pump.

7. In order to keep the A/C you will need to modify the ac lines from an shop that can make custom ones. And you will need to get some longer bolt that fit the front crossmember to accomodate 3" worth of washers used to space out the front cross memeber. This will allow room for the H22 compressor to fit down below. It will however lower the front crossmember. (I want to thank Osvoldo516 for his contribution to this information - )







8. Powersteering can be kept as well, you will need the have the H22 bracket and your preludes hardline from the sensor to the rack sent to me to be fabricated to work properly in the swap.
Here is the H22 bracket I need to make it work (Thank you Tmoney for your contribution into solving the powersteering issue - ):





9. Axles can be done through Gator axles or Raxles.com. Give Marty a call at raxles.com and he will tell you the specs. Call Glen at Gator axles as well.

Edit: 3-29-2009
Another cheaper option that has been done, is to use the stock: 90-93 Accord axles for the swap. This has been done by B20luda and a few other members and they said no modification needs to be done.

*Note: this is only for the 90-91 Preludes, the 88-89 will need to change their hubs to 90-91 hubs.
90-91 28 spline count hubs.. Or if not, then purchase Raxles.com axles.

The choice is yours. Here is an example of Raxles work. (Edit) I forgot to mention that the recommendation for upgrading the hubs to the 90-91 Hubs due to it having 28 spline count, the 88-89 Preludes have only 26 spline count. It is not necessary but was recommended by Gator axles due to the increase in power:



Installed on Osvlado516's lude:




10. There is a High Recommendation to change out the auto belt tentioner to a manual one due the the faliure rate of the auto one. Here is the writeup link below(A big Thank You to 98Vtec for his write-up):

H23 Manual:

11. I forgot to state that you need the Rear Engine bracket from the 4th or 5th gen Prelude, some H22's swaps are sold with Accord rear brackets. It is important that you note this down or AZ Races' rear engine mount will not fit.





12. Clutch Swap for the H22 swap:

This thread will continue to get updates as necessary. I welcome all input for this swap as there are many ways to do things. I know this will help a lot of people who are deciding whether they want to do this or not.

Enjoy!!

Sweet!!!! Sean, thanks for all of this important info. This should help everyone with the swap.

Thanks for the info on the shifter cables too.

Always here to help when I can. I felt its time to start organizing everyones projects and put it all in one place and update it as necessary. That way it cuts down on unecessary threads and posts. It wont eliminate it but it should help cut down some.

Now when someone pulls a search they should get this thread.

[johcamp]

Nice sean. This is very informative. When i get my turbo'd lude done and sell my house an h22 is going into the beater. This will be a good reference for me!!!

Thanks!

[Mephastapholes]

Got a recommendation for which after market pulley to use? I really like Unorthodox racing's stuff.

That will be up to you, almost all H22 aftermaket stuff can be installed on the motor. Except the super charger system, I dont believe we have enough clearance for all the bracketry and pulley system. This has not been tried yet.

But all turbo kits will fit with some minor modding for the charge piping in the front of the engine.

[89SIracer]

awesome thread. my only question is, how much would it cost 2 swap minus motor/tranny cost, no ac, w/ ps, and sending out harness?

That is a question only you can answer. There are no prices on this thread because we all have different hook ups and ways to get parts for different prices. And prices change to reflect cost increases.

I only provided the checklist, you will need to do the search for the motor package and wiring, axles and so forth. Just get in contact with rywire.com for the harness work. Nothing is set in stone as far as prices go.

[GUESSMAN]

One more question.

Since my 88 S didn't have Cruise Control, I didn't bother reading anything about being able to keep it.
My question is, do you have to do anything special to still be able to use it with the swap?

I would consult with the online manual on that, because there are quite a few connections to make it all work.

I am not sure how what you need to do to make a non cruise control model work with a cruise control one.

[Dark_star_Raceing]

Awesome Sean,Glad to see this on here!

It's cool. Sorry about being a newbie. I'll just look my other Lude over really good because it has cruise on it.

I just didn't know if I was going to be able to keep cruise (if I had it) with a H22A swap.

Thanks again Sean

[blahblah311]

you da man 1funryd

[osvaldo516]

Awesome!!!!!

[TheMachinist]

Nice write up Sean. Your like the king of prelude information.

[1funryd]

Tanx guys! And I will keep updating it as information comes along.

[team123luder]

You need to update the information.


90 2.0S/90-91 2.0Si models are still OBD0 and will require you to upgrade to an OBD1 format. 90-91 Si models are OBD1.

Shifter boxes and cables.... You need either 92-96 Prelude shifter box AND cables, 90-96 Accord shifter box AND cables or 97-2001 Prelude shifter box and Cables.

[Gargoyle24]

are the same parts needed for all versions of the h22?

[danny_d19]

It's about time you put this together


lol Nice work as usual Sean

[team123luder]

This is for an OBD1 H22 swap ONLY!

[jlude90]

carb to H22 is an absolute bitch i think it should be noted, i would HIGHLY recommend putting the Si interior harness in first, unless you are VERY VERY good at wiring or want to pay through the nose if you don't have a hookup

but with the Si wiring its a cinch

[BoostJunkie]

you gonna throw anything out there about the hubs?

i believe i remember reading that you said to use the 90-91 hubs because they were stronger than the 88-89 hubs.

i suppose you dont have to. but it should be noted.

[90preludeLad]

this is perfect. thanks a lot sean. i will deffinetly be using this someday.

It has been added.

And I want to thank all of you for the support of this thread.
Because I know eventually half of the luders on here will want to swap to the H22 due to the availability of parts and engines. Well at least in theory.

I was waiting for as much information as possible to gather, and I was a little swamped with some other projects as well.

Sean
