AZ Race H22 3g Mounts Review
Parts Needed:
1. AZ Race Mounts - sold through me(1FunRyd - contact:
[email protected])
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.
Here is the link with many pictures to the Rywire H22 modified engine Harness:

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:

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:
Update: 11-04-2010 - Alternate Axles - 90-93 Accord 5 speed
axles
*As per B20luda - For an alternate source for axles we can use the 90-93 5 speed axles in
stock form.
Note: for the 88-89 Ludes, you will need to swap the outer cups of those axles for the 88-89
cups to make it work, or you can do what I did and purchase a junkyard set of 90-91 front
hubs and do the swap. Those hubs are a straight bolt in.
Also when choosing the H22 motor, in order for you to use the Accord axles, you will need to
purchase the 90-98 Accord Mid-shaft to make this combo work.
The 92-01 Prelude Mid-shaft does not work due to the 90-98 Accord mid-shaft has a female
spline end, versus the Prelude mid-shaft has the male spline end
He is using them in his 611whp boosted H22 swap.

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):

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.

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!!
**Note: This will be in the Stickies under the --**3rd Gen Performance Upgrade
Inventory**--

axles

Andy I know its not new news, but its more precise information than what has been posted in
years past.
We always get a statement like "I used Accord axles..." but with no detailed information like
what that person did to make it work.
We need to be very clear when making any kind of statement so its not just hear say.
For example: "I used 5 speed 90-93 Accord driver and passenger axles for the H22 swap.
There was no modifying to make it work..." (For example only, do not use this info.)
That is why I posted this information, because I recieved credible information that has details
we can all use.
So to be clear for all, when using the manual 90-93 Accord driver and passenger axles, you
will need to have the 90-98 Mid-shaft in order to make these work. The passenger side will
work but not the driver side if you do not swap the mid-shaft to the 90-98 Accord version.
And also all 88-89 Ludes will need to swap to the 90-91 front hubs with the 28 spline count
in order to make this whole setup work.
Other than that, everyone can call Marty at www.raxles.com and he can make hybrid axles for
the 88-89 ludes that still have their stock 26 spline hibs.
