Alright you guys have convinced me that an M30 swap will achieve my goal of a torquey car to break the rear end loose once and while and will be easier than turbocharging a SETA 2.7i hybrid. After hunting through the threads here and searching some other forums I’ve found a 5-series enthusiast willing to part with the following set up:

M30B35 complete from an e34 with 110k miles and had oil in the coolant, assuming headgasket, was from a 5 spd car but transmission is sold for a 5 spd swap

179 ecu and un-cut engine bay harness from the e34

Getrag 260/6 with flywheel and clutch from an ’88 e28 535is that was rear ended with 110k miles

Driveshaft from the same e28 535is

3.25 LSD from e28 535is

Radiator (newer than 110k) from e28 535is

New engine gasket kit including headgasket

All for the picked up price of $1200, which is about a 5 hour drive from where I live.

Does that seem like a fair deal? Anything else from the e28 535is I should ask for to help with the swap?

Thanks.
