Eta tranny work with an M50?

[Jand3rson]

I searched around for a while, but couldn't really find a clear answer. I just need to know if my 260 from my '86 es will work with an M50. My car is an 01/86, so I'm pretty sure it has the single mass flywheel, not the double. Can anyone give me a definite answer?

im pretty sure it does. m20 eta and i are the same pretty much. can use your driveshaft too.
do i see a swap in your future?!?!?

It works. Im running mine. Be sure that you use all of your m20 stuff though. I have an s50 flywheel (basically dual mass m50) and clutch and an m50 starter. I seem to have starter gear mesh issues. Im switching to m20 starter/flywheel to see what that does.

my friends blue e30 has the stock 89i trans with s52 flywheel and clutch with an unknown starter (he was told it was from m54). Somehow this combo worked perfectly for him.

i have a e trans josh. kinda looks off, when in 1st it looks like its in 3rd, but doesnt hit the console. using m20 fly, e30m3 clutch and the stock starter.

Josh, I told you the other night. You can use it, you will just have shifter issues when it comes to centering it due to the 10 degree shift.

If you arent going to listen to me, then dont ask! Or stop wasting time creating these threads!

Yep, it'll work Josh. My trans is actually from an '86 eta also.

You'll need to cut the rod and weld it after adjusting the angle 10*, use the M20 flywheel and starter. A good clutch setup to use is Sachs E30 M3 disk and pressure plate. Sport pressure plate and race disk if it's a 3.0 or 3.2L.

the selector rod is very easy to weld.

NO welding required:razz:

on the e tranny housing, its a completely different shifter setup than an i tranny, unless its been changed.

put in vise, and bend.... why do it any other way?

are you referring to the sheet metal vs. the aluminum carriers? I think they stopped using them early on. I know thats the one thing we forgot when I was swapping an m10 for an m20 with g260 trans. luckily i found the parts quick.

my '86 build has the aluminum carrier. I think the only real difference is the reference sensor holes.

It was mid 86 they went to the alum carrier. My 87 eta had an alum.
