Has anyone swapped in an S54 into an E34? I'm looking for guide or swap information, TIA.

S54 in E34

The E34 M50 front sump pan and mount arms should work. The exhaust will probably package ok. Not sure if that oil pump can supply the S54's dual VANOS or if you'd be able to use the S54 pump or if you'd have to really get creative.
Plenum to brake booster interference may or may not be a thing, but the E34 M60 remote mount booster & master cylinder or the E32 hydroboost should fix all that just fine.
The E34 was built with the 420g transmission, so an E34 540i/M6 trans crossmember and driveshaft would probably work.
Beyond that it's just plumbing, wiring and DME.

The mechanics can always be figured out. Also if you need swap coding for free minus the ODB cable: Github XDFs for TunerPro
