Swap question: M30 or M50tu?

Hello all. Quick q. I just located and picked up a really clean M30 Series II engine and trans out of an e28 with under 100k kms on it. While there, I also found an '93 525i (M50, single VANOS) with 5 speed for very, very cheap.

So, I went in to get the parts for the M30 swap, and now wonder if I should go M50 instead. My car is an '87 eta car with a slipping clutch, and enough oil leaks that I think it would be more economical and interesting to do a drivetrain swap. Obviously, I'd do the work myself to keep it economical!

Long term plan would be Megasquirt and boost, as I've done on past projects.

Thanks all,

Do the M50 swap and sell me the tranny from the M30 Provided it's a manual transmission.
