The cost to repair my current transmission, after labor, with new syncros and other parts would be about the same, or more, as just buying a M2B4 LSD transmission.
I'd rather have a quaife setup, but this would suffice. Anything is better than the stock open diff.
So...
Who among you have bought a M2B4 transmission?
Where did you get it?
How much?
How does it perform over the stock manual transmission?
Is it true that some of them still suffer from the 5th gear grind?
The only source I have found thus far is some site called ebay.com
People sell them periodically on message boards, but those are most likely abused more.
I got mine from a friend($100) yup for $100! He got it from www.hmotorsonline.com He got it with his JDM H22.
It preforms well. I auto-x with it and it works VERY well! The shorter ratios 1-3 are really nice and the longer 5th is great!
Yea it does suffer from 5th gear grind... in fact i have lost 5th gear all together But when winter hit's here in upstate ny i will pull the tranny (AGAIN) and replace the 5th gear syncro sleeve and syncro.
If there are any question, let me know!
Good luck

I find my 5th gear grind is avoidable with careful slow double shifting. I hope it's not too bad an issue.

JDM M2B4 does not had quaife lsd in it...
I'm was saying, I would rather have a Quife LSD on my USDM transmission, but a M2B4 Transmission would be a suitable more affordable alternative. I know the M2B4 doesn't come with quaife.
Looking through some old threads I found some more suppliers.
Now, I read a few threads about the possibility of the M2B4 LSD breaking internally if the front wheel lift. That kinda makes me lean towards the quife setup, since I would like to get on the track.
Are all the M2B4 LSD's susceptible to breaking after wheel lift?
Are there certain types that don't have this problem?
1.I got mine from a friend($100) yup for $100! :eek
Wow, thats a deal.

1, yea he was getting rid of his car (with the JDM h22 and the M2b4 in it and told me to do the labor and give him $100 and we would call it a deal!!
2. Well i have had issues with the 5th gear before i even got the car... and when i had it apart... The syncro sleeve is SHOT and the syncro is pretty bad. I opened the case when i had the tranny out installing a new clutch. Its not that big of a deal right now... the car is not a daily driver.
3-4. That possible brakeage is a "trait" of a Torson(sp) diff. I know that there are threads about this possibally happining with the quaife as well. I can not see this happing without SEVER abuse.
SlowSi:
As far as crusing speeds... With the 215/45/16 at 80mph i was seeing just north of 3k? It has been a few months since i have gone that fast...See #2.
DR:
i think that you can change the ratios and be in SM class. Becasue it is a OEM tranny?

I've decided on Quaife. Thanks for the input guys.
Good decision! I was going to go that route but the price of the M2b4 was something that i could not pass up!

that does constitute a taller 5th gear. well at least over the USDM VTEC transmission i believe its the M2F4? well anyway im at about 4.3 going 80. he says hes at 3.9 which means hes at the same rpms going 80 as i am going 70. my synchros are all pretty much shot so i think im going to be investing into the M2B4
