Let's us not forget what car was used for the ring taxi though..........
If it were me, I’d go with a built s54. Cams, airbox, exhaust, and tune gets them up pretty close to 400hp as it is. And if you go even further and stroke it to 3.5L or so, then you can make even more power and the torque goes up a fair bit too (though obviously still not as much as the s62). End result would probably feel akin to a modern e34 m5IMO, if you do that than it's almost pointless as you'd have a lot of cost involved and weight would probably be almost similar.
I mentioned S52 for a reason as it'd be probably be much easier and less costly to do that plus the 5 speed manual.
While S52 is only 50 HP more than M52, it's enough to make a nice difference and car would definitely be more nimble vs S62 / steel subframe swap.
If you have the M52 non-TU, then yeah, S52 is pretty much a direct swap. For M52TUs and especially M54s, the S54 electronics would be a better match, but it would still by no means be a straight forward swap. There is a thread on bimmerforums where a bunch of us discuss the feasibility and have a theoretical plan of attack, but there's only a couple of not really well documented swaps running around out there.I haven't done any research. The only reason I'm considering S52 is the cost and less complexity to do swap. Being relatively closely related to my M52, I see easier work with ECU, same no drive by wire throttle etc...
If I could get it close to 300 HP I'd be happy.
Yes, I have M52 non TU, hence my interest in S52. Obviously, I 'd have to consider diff, driveshaft etc... but if I could find healthy S52 and correct MT, it'd be a good start.If you have the M52 non-TU, then yeah, S52 is pretty much a direct swap.

Yet many people constantly think high mileage cars are worn by default. Those 430k miles are much better for the engine than 100k miles in short trips and multiple cold starts.My good friend has a 2000 528i sport auto that has about 430,000 miles on it! Original transmission and all he ever did was change the filter and top off the fluid. Pulled exhaust at the flange recently and said it was so clean inside on the cat side you could eat off of it. He has a solid one hour one way commute he drove for the past 14 years...
Rust will be the only thing to bring it down and mostly just the body and jack points.

Amazing E9. Looks like a nut and bolt restoration. Congrats! (former 20+ year in family since new E3 owner here; we didn't have megasquirt in the '80s but triple 45DCOEs coupled with a Schrick 304 cam, porting, high comp pistons, etc, made for an awesome M30 back in the day).Hi Folks, new member here, just jumping in for a little comment. I really enjoy driving BMW's and I think half the fun in owning one is doing little things that make them unique or special, even if that unique thing is keeping it all original. I'm new to M5's having picked up one recently and driving it a bit today I notice that it's much beefier than my other BMWs. I have an e36 M3 which is a super fun car and an e9 which consumes an inordinate amount of my life because I'm always f%#(ing with it. I find with the older BMWs things seem to be less trouble when they're close to stock. Anyhow, just wanted to pop into the discussion and throw in my 2 cents I included a few shots of the e9 I hope to get it to the dyno machine this week or next to tune the Megasquirt.
