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.

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? laugh
