Looking for a blank canvas for your next track car? How about this E28-chassis BMW 5 Series roller?
The seller notes this car comes fitted with a roll cage as well as upgraded suspension and brakes–all you’ll need to add is a new engine, transmission and fuel cell.
So, what’s your engine of choice? BMW straight-six? LS V8? Something electric? …
Maserati Bi-turbo
A rotary ... i mean ... a Wankel - that keeps it German, right?
There's an s54 for sale on marketplace near me...
But honestly I think whoever buys this should look to the most recent winner of the $2000 challenge for drivetrain inspiration!
What it normally has - a natutally-aspirated straight six.
That's right, I'm talking about the Atlas 4200! All aluminum with torque for days.

I was gonna go with something a bit earlier...
Needs an OM606
The classic choice would be an S38 out of an e28 M5, or even better the updated S38 out of an e34 M5. A newer and probably better choice would be an S54 out of an e46 M3, I know a couple guys who have done that. A GM LS engine has been done multiple times, but it will require some modifications to the brake master cylinder booster mounting to make a V8 fit. The original M30 big six that came in these cars originally responds well to turbocharging - there used to be a company called Turbocharging Dynamics or TCD that made a nice kit for this but they are out of production, so you're best off these days building your own exhaust manifold, intercooler and piping.

It's hard to go wrong with an S54, it's a wonderful engine. If budget wasn't a concern, I'd go with an S65 over an LS though.
Practically -- M50 or S52 with 3.23 lsd.
Ambitiously -- N55
I'm tired of LS swaps and K swaps. How about a WW1 era Liberty V-12? 
Let's do a Cummins 2.8, cuz these were better with deezels. Call it an endurance racer.

If budget isn't a concern, S85 with equal-length headers for that classic F1 howl.

Umm, this is a German car, no? Wouldn't a Messershmitt engine be more appropriate. Keeping it "all German", right? 
This one, however, needs more work than the entire car...
S54. Done. Turbocharge if needed

Messerschmitt planes didn't use Messerschmitt engines. The BF-109 used a Daimler Benz DB-605 for instance. How about this BMW V1 V-12? Might as well keep it in the family. I'm not sure they would be too happy if we borrowed it from the museum...
In reply to ProDarwin :
Good luck fitting that into an e28. It would take two of their engine compartments.
5.7 Hemi. Because a guy has one and owes me money.
S85B50 Plus the factory 6 speed.
