e46 m3's are a bit heavier and nobody has really turbo'd one yet successfully. Active has a page of 600+hp cars they have done and several of them are e36 m3s...not a single E46 there. The only kits out there for them now are SC, which do put out some pretty decent numbers but they're very pricey.

There is a guy in California who has the fastest 1/4 mile time now, you probably saw jmweb's time in a phoenix yellow m3 in miami which got a time of 11.98, which was recenly beat with 11.972 by the california guy tazam3. Both times could be a lot better -- jmweb's car was SMG which is terrible for launching at the drag strip, and tazam3's car was run at a poor track 2700ft above sea level. Both cars have the yet-to-be-released active stage III SC kit.

An ace driver in stock m3 can get into the high 12s, so those times can definetally get better. For the most part though it is a low-13 second car.

For the money it takes to SC the e46 m3 you could put together a separate car (or two) that would spank it in the 1/4. For the money I paid for my car I could have put together a fleet of cars that would own it so don't worry, there are probably no bruised egos on the BMW owner's part unless he made a mistake buying a new M3 thinking it was a fast car
