Dredder-are you running a stock 318ti 5 speed? I thought that would also keep costs down.

Guys please help me. I am stil confused because I don't have a good list of the things I need to have an m50 swap.
I know I need the engine and all the electronics, front 325 brakes, 325 cluster.
I don't know if I need the transmision(gear box), drive shaft, diff. So can anyone please help me with this one.
I own a 1994 Ti(M42).
Thanks.

you need the diff if you want to make sure yours won't break soon. The driveshaft serves a fitment to diff issue, and the transmission should be OK unless you want to supercharge or turbocharge later

So I can use my curent transmision. This is a good thing because I can save some money. I think that the curent diff will be just fine because I have seen some m50/52 swaps on the ti and they all say that the diff hold to that kind of power.
Thank you for your reply.

P.S. :SHould I go for a new clutch kit such as an m3 cluctch?

as i see it, the issue with the diff isn't all whether or not it can handle the power. most stock ti diffs are open diffs. with the 6, i imagine you'll be spinning one wheel way more often that you would have with the 4. the advantage of going to a large case diff is more that you'll gain a limited slip diff (LSD) than just increased power handling (although that would be good as well).

Wel then I will do the swap and later when I will have the necesery cash I will do the diff also.
Thanks for all the answers. I just found a guy that sells a 325 bmw and he asks for the engine, all the electronics, front springs, front brake calipers for somthing like 800 euros.

One more thing... After an m50 swap do I need to get the EWS realigned at a dealer considering that my car is a 1994 ti.

yes. EWS needs to be aligned for ANY engine


as for the diff, I broke mine with just a supercharger, so thats why I replaced the 3.45 LSD one I had later from the clubsport

So after I install the engine and all the wire harnes I sholdn't try to start it and just go down do a bmw dealer and ask the to align the EWS??

sorry for slow reply. I'm not COMPLETELY sure all OBD1 cars have EWS. Please do your research, but the rest of the process is correct

Don't know if this was mentioned, but what is the exhaust setup on the s50 for our ti? Would a euro s50 be the same?

I found it, M3 exhaust up to 330 muffler. Still the same for the euro s50?

Also, I have bilstein sports on my car now, but would I need to change the front to M3 bilsteins or can I keep the ones I have?

I can't answer either of those :(

probably yes and yes

I am using the M3 motor, ti tranny and M roadster diff (well, complete sub-frame too) and I am using the ti drive shaft. The M roadster drive shaft is too short...

Any of the sixes have a very good chance of breaking the stock ti diff. It WILL happen, the only question is when. Budget for it, and take care of it or you'll be walking at some point...
