Funny,

Good eye Paul. In our arrogance, we all thought he was WAAAAAAY off the deep end. Has he been back yet?

This post went further than I thought it would.......

I read the E30 S54 swap- anything is possible - that's the same guy that did it in the E46 323i. I didn't see that he wanted it in an '05 525i. In that case - why ruin a perfectly fine 525? Go buy an M5 it'll prob cost the same in the end.

No, it'll cost more. Way more.

I'm agreeing with Jon on this thread, but for giggles...

A couple of years ago, my boss bought a wrecked 850CSi. All US 850CSis are OBDI, hence all are <= '95, no titled '96es because they're not OBDII (even when there were a few sitting on dealer lots INTO '96). The S70 went into a 1994 Euro 3.8 M5: more or less a physically direct fit -- the subframe and motor mounts are bolt and go, the E34 M5 uses hydroboost (as do all V12 BMWs) so no need to do brake work, off the shelf cooling system and (some) exhaust components were available as well. Still, it took a year and a half in "free" time to assemble the car -- work done by two very knowledgable people. The most difficult part was the wiring harness -- three separate harnesses were made into one. It also wasn't cheap, but the car has a lot of goodies, probably on the order of 30 grand worth of work and parts.

Now, there are wrecked E60 M5s around, but you'll pay a lot to get one. Once one is located and purchased, start fabricating. It's not cheap, and I doubt it's worth it given the alternatives, but that's all up to you.
