God I miss that car;-(. That was before it was even fast lol.

(Yea, that was my roadster, stock bottom end with the "little" turbo on it) The funny thing is it really did still laydown 550whp with 3 cylinders gone. My 95 S52 M3 track toy was a more modest ~500whp daily driver/RR car. The seats really made it not too fun on the street.
Now, I'd give a left nut to have some of the money back I had in those cars.
i am thinking about buying my parents m roadster from them because i know they never drive it and i'm sure they wouldn't mind the garage space. is there anything i can do to get it around the 450-480 hp level without going with forced induction, and how much would i be looking at spending?
If you want a 450hp M Roadster without forced induction, put a modded small block chevy in it. An estimate to get you to that level is $15k with all the supporting mods needed to make the conversion.
Both the S52 and S54 are iron block. The LS1 and up came with an aluminum block, so no you aren't taking a weight penalty. You can find centrifugal superchargers, blowers, and turbos for both the chevy and the S52.
This video is from when he just closed the wastegate and let it run anything it could on the T60-1. It peaked at 24psi and tapered to 17psi due to air leaking out of multiple places. After running many passes like this, it went back to the shop and dynoed 545/585 wheel with low compression on 3 cylinders. Teardown revealed 2 cracked ring lands. It was going to be built as a drag car, but has changed. This car is in my garage to be built as a SCCA SM2 autocross car. It's still Shawn's car.
Valetudospang, talk to George the owner of ICS Performance of Stanford, CN. He owns a black m coupe twin turbo got a new fuel system running a stock block. His car is a beauty he smokes in 2nd with ease. He dynoed at over 700rwhp and over 550tq. You can find some videos on it by looking up the YouTube account named "Dynoflash" best tuners for your import cars they do crazy shit with Evos Suburus and BMWs. Hope I could be of help!
The motor internals were 100% stock. It was simply putting lots of boost in a stock motor to see what it could handle. For good people to look to for building a motor I would say... ICS, Maximum PSI, Technique Tuning, and Active Autowerke.

That is Shawn Bowen's turbocharged S52 M Roadster. He toasted the engine at the end of that season, but was last reported to be building a new engine and larger turbo combination. that was in 2004 from memory.

To put an American engine in a German car and vice versa is HERESY!!! >:(

S52....it figures. An S54 would have detonated long before Shawn's S52 did.
The S52 is almost bullet proof. If Shawn hadn't been hurling Uranium tipped bullets down the track he would have been OK!
