I recently obtained an H22A4 motor w/ what is supposed to be a JDM LSD tranny on it.

I am not real sure how to identify or cross refernce any of the numbers on it to decifer whtether or not it's genuine.

Any help or insight would be great.

well if its an LSD u should be able to see all the way through the differential and not see a bar in the way. if it was out of a lude the tranny code should read M2B4. if it was out of something else look through posts by satan_srv he made one a while back with all the different tranny codes. also check in prelude specs and stats at the top of the page under essential prelude links... hope this helps

 

Prelude specs and stats and satan_srv proved to be extremely informative. This H22 venture is all new to me and I have already found some valuable answers here.

THANKS!

It turns out that I have the M2J5 which appears to be a JDM tranny w/out the LSD...RRRRRRR (not real happy about that!). I do anticipate some good results out of the intended setup though.

I have two Civic H/B's, a '93 Si and a '00 CX. The '00 CX will be the recipient of the H22A4 w/ the M2J5 w/ a bunch of bolt on goodies and a power adder of some sort....if I can get the car to hook and dial in the motor/suspension combo.

Any suggestions on a proven suspension combo for this setup w/ a turbo?

So far, all I have suspension related is a SPC Billet Camber correction kit and a set of Place Racing motor mounts( not really suspension related...but it ought to keep the motor secure).

I've been holding off on purchasing the suspension until I spoke w/ some others about their setups and how they keep their tires planted! I have a bad feeling that this particular car is gonna spin the tires pretty hard with a radial on it (for street use) and spin them even HARDER with a turbo on it...with that in mind, would nitrous be a better avenue?

Again, any ideas and/or suggestions would be both helpful and insightful!

THANKS for such quick RE/help!

m2j5? I don't think that's an H22a tranny...

Considering the S model F22a tranny is M2L5 in USDM land I would hazard a guess you have a poorly geared S model tranny bolted on there.

 

was there an M2B4 without LSD? Between a guy selling one who claimed it wasn't LSD, but he could see through the driveshaft holes unobstructed, and osakamotors or another company that said all their M2B4 transmissions in stock were non-LSD, I got a little confused.

then they don't know what they are talking about. As my tranny thread states the m2a4 is the non-lsd jdm tranny.

 

The specs I was quoting from:

4th Gen

4 - 0.903 - 1.034 - 1.071
5 - 0.705 - 0.812 - 0.870
FD 4.062 - 4.266 - 4.266
*Above info taken from USDM Helms manual.

5. 0.787 5. 0.787 5. 0.787
FD 4.266 FD 4.062 FD 4.266
*Above info taken from teardown and tooth counts.

---may have proved to be a little confusing. I thought that the bolded type (M2J5)was for a JDM non LSD trans for the H22....maybe not.

I definitely see a bar so that rules out the LSD issue, but now I'm concerned that I may have a bunk trans for this setup!

The exact number off of the trans is M2J5-3000338...are there any sites/manuals that exist to cross reference the number outside of a Honda database to see its history and/or origin of my tranny?

Not to steer too far away from my trany concerns but,
Have you engineered an effective suspension for this application yet?

 

lsd quaife

You're absolutely positive of this? Because if so, lol, there's a helluva deal to be had on a Honda LSD transmission, I just need to remember which place it was I e-mailed.

oh, joel, also: if the tag on the transmission has been removed, is there any other place to get the code from on the casing?

 

M2A4 = Non LSD JDM
M2B4 = LSD JDM

 

I wish I still had that e-mail, it was osaka or noyan, I'm pretty sure, that I exhanged a few e-mails with, and basically I had asked for a quote on an "M2B4 LSD transmission", and they said that while they had several M2B4s in stock, none of them were equipped with LSD, and after I questioned that, they told me there are two types of M2B4, one w/ LSD, and one w/o. I still wasn'te sure that it was true, because I've read the posts, but I think there was also an e-mail where they said they new what to look out for to see whether a transmission had an LSD installed, but nothing specific. Hmm... well, I e-mailed noyan for a fresh quote, I'll see what they say now.

Exactly man...look at the specs of the M2J5....it is almost the same as the f22a USDM tranny M2L5 listed up there as well. ugh that 4.062 final drive that tranny will be a DOG on an H22a. That's not an H22a tranny, sorry.

 

Well...now that I've come to terms with the fact that my tranny sux.

How do you feel about the H22A4?

It's down 20HP from the JDM or so but, Is it capable of producing some power as well as hold up to the abuse that she'll most definitely endure?

Revhard, Turbonetics, Greddy, HKS, Turbo Specialties.... any of these companies stand out above another as a turbo manufacturer to use for the H2A4 setup?

I want to set this thing up as a boosted, power producing, tire hookin' Civic!

HUH? Quaife is a LSD!

 

I realize that a Quaife is what produces the equivalent half-shaft torque displacement but I did not realize that the M2J5 had a quaife in it!

Is that what you're saying?

Satan_SRV make it quite clear that this tranny is not the M2B4 which is the JDM LSD version, in fact I have the equivalent of a USDM F22A.

After reviewing all of the posts and facts it appears that the M2B4 is the best trans to run w/ this setup if LSD is what you're seeking.

The real stinger in this whole deal is that the guy whom I purchased the swap from paid $1440 extra for the M2B4 JDM LSD tranny not the M2J5 non-LSD tranny, and him like myself had no idea how to verify it until now.

Now that I can....we are trying to determine first and foremost whether or not it does or does not have a Quaife in it and second, how to obtain the M2B4 as originally envisioned and purchased if it does not.

Even best case scenario the M2J5 does have a quaife in it... the fact that I can see a bar through it is very puzzling......hmmmmm.

Any insight?

 

WOW....I feel like a JACKASS. I thought the last post was in response to my own.

Funny you point out that fact because I too thought that they were the same and was puzzled by the post!

I now retract my last post &gt;&gt;&gt;&gt;&gt;&gt; LMAO &lt;&lt;&lt;&lt;&lt;&lt;

...Sorry McFred!!

 

sorry for being vauge, did not mean to confuse.

the Pirate

 

revhard, fmax, greddy all have turbo kits for h22a engine.

 

Any preference?

I am familiar with the specs of most of the kits but I've never set up a boosted H22A4. Now I am trying to accomplish this setup and be able to use it in a practical means (i.e. street and strip use).

I'm gonna use a variable kit up to 18 psi in order to run 6-8 psi on the street and adjustable to 12-15 psi for the strip.

Problem number one is finding a turbo that 's that flexible, reliable and consistent as well. Problem number two is figuring out how to plant all that power to the pavement and use it.

I'd like to find a time tested suspension and turbo combo that has proven itself to hopefully bypass the learning curve that maybe somebody has already absorbed.

,Kazi is knowledge HUNGRY....lol!

 

do you plan on sleeving the motor in order to achieve that much boost? Ringlands on the h22 are prone to giving out after 8-10 psi. while i know there are cars out there boosting more than that on stock blocks, i just dont think its safe to go past 8-10 unless you have a 2nd ride

 

I suggest you build your bottom end if you want to boost that high... get good engine management also [hondata or ems]. Putting all the power to the ground will require an lsd (quaife is one of the best) and i would also upgrade your axles also. get good tires with a lot of bite and nice suspension, you should be set.

 

For the record, some images to use as reference. Its for sale btw (shame less plug)

 

Well, I have the 2nd ride covered. As far as the sleeving goes, I hadn't considered it at this point. I basically planned to drop it in get it turn key and dial in the motor. From there I was going to make a decision on the power adder of choice.

I kinda had a feeling that the rings and/or bearings would be the first to give under intense boost.

----------------------------------------------------------------------------------------------

I have the H22A4 w/ the M2J5 tranny, Place Racing Motor Mounts, Prelude Linkage, Civic CX Wiring Harness, H22A4 Wiring Harness, All new accessories (i.e. starter, alternator, cap, rotor, etc.), Centerforce Dual Friction Clutch and Flywheel, FULL Greddy Exhaust, SPC Camber Correction Kit, Tenzo R Big Brake Kit, GSR Rear Disc Conversion, and a trunk relocated Optima Yellow Top battery....

Are there any other components that I will need to make this swap turn key outside of an ECU and suspension components?

With that in mind.....which ECU will be best with this particular setup?

Also, any suspension ideas and/or suggestions on which header, manifold, cam sprockets, pulleys, and throttle body to go with?

Pretty much...can somebody build my motor (LMAO). All jokes aside, I just like to get feedback and insight for other enthusiasts that have already done and achieved what I want to accomplish.

THANKS for everyone's support!
