I have a 5 speed 93 turbo legacy 2.2 and i found a transmission but its an EJ20T i was wondering if it would fit my car

Off the top of my head, and without searching, I have two relevant beliefs

There is no such engine code as EJ20T, and so we will probably guess that the engine that this transmission was paired to is an EJ20G

I believe that if the gearbox was imported attached to a JDM engine the odds of the ratio being 3.90:1 are low, which means the odds that it will mate with your differential are low.

I will definitely mate with your motor, and so it will fit if you are willing to change your rear differential (if need be)

Also, if you do end up needing a different rear differential for it, the odds of finding one in a USDM Subaru are pretty Good, so that is no reason to be intimidated

That is a hysterical typo. I could not stop laughing at that one, sorry.

What is the TY number on the front of the tranny? That will tell you what rear diff it should be paired with. I may be able to look it up if I can find the blasted tranny chart I compiled a few years ago.

The TY number is TY752VJ2AA if u can help thanks.

Is that the # off trans you found?? If it is, I think that's a first gen legacy turbo transmission (in which case FD should be 3.9). My chart says that one's a 3.9. but there is a "?" next to it. I'm pretty sure that number is 1993 MY though, so 3.9 would be correct.

Now that I've written all that, I realize you must have given me the # off the transmission you're trying to replace...

The TY number of the trans you are looking at buying will tell you what you need to know.

If that's the number on the tranny you want to put in that's a USDM 1993 Legacy SS 5MT witgh 3.9FD. That's not a JDM number.

Thats the number off the side of the tranny on my car now, and the one im looking at is below and these are the gear ratios for it

. 1st 2nd 3rd 4th 5th
JDM Impreza WRX & WRX Sti TY752VB4AA 3.45 2.06 1.44 1.08 0.82
Reverse Final drive
3.41 4.11

wondering if they will work with mine

Ok well it says right there the final drive is 4.11. That means you will need to also find a 4.11 rear dif. In order to make that trans work. Those can be found on certain impreza models from the 90's I believe.

Are rear diffs expensive cuz i found some for like $500 or is it just a part i need

biggreen96 · Post by **biggreen96** » Sun Oct 25, 2009 1:06 am

They aren't 500 for a stock unit. More like 100 at the junkyard. Of course if you want a quality limited slip you could spend around 1000. Search around.

Ha. I have a 4.111 if you need it. I couldn't get rid of the thing a few months ago. Let me know if you want it.

And yes, I forgot to mention, that TY number you gave is definitely USDM, not JDM.

SubieBro · Post by **SubieBro** » Mon Oct 26, 2009 7:33 am
