E46 performance
The M3s S54 naturally aspirated engine produces 343 PS (252 kW; 338 hp) / 3.2 litre.
EURO Models
  • 343 PS (252 kW; 338 hp) @ 7900 rpm
  • Torque: 365 N·m (269 lb·ft) @ 4900 rpm
  • 0-100 km/h (62 mph) — 5.1 s for Manual and SMG, 5.5 s for cabriolet
  • 1/4 Mile — 13.3 s @ 104 mph (167.4 km/h)
  • Top Speed: 155 mph (249 km/h)(electronically limited); 191.38 mph (308.00 km/h) (delimited)
  • Skid Pad: 0.89g[12]
This is what Wikipedia brought up times wise. I would have thought a JDM Spec R would hit 102mph on he 1/4mile with roughly 250bhp, so the two aren't far off the same power to weight ratio. Personally, I've managedd a 12.9 at 113mph on a GT3071R at 1.2 bar with a standard engine. The M3 has traction contol though doesn't it? so it'll be far esier to egt off the line.

yeah.. M3 has traction control.. I raced against a Z4 M last year.. And we got off exactly the same.. then In 3:rd gear i passed It and then bye bye.. but I think the driver In Z4 did something wrong,, I cant win that easy...

I had an e46 m3 before my s15 and personally I think the 15 is quicker,might just be the turbo makes it feel quicker lol but there isn't much in it

I think a S15 beats M3.. but If It's A M3 with smg box,, then we have problem, they shift fast as hell.. just looked at one on a race here.. that shifting Is flawless..

I've only encountered one M3, but I had about 400bhp so it was hard not to drive into the back of it :D

I've driven an e46 M3 with the SMG as well, they seems slow as the power delivery is so linear. The paddles make it great fun in the twisties :D

Yeah, I've raced one too and just got past with 319bhp and similar torque. My 1/4 mile is 13.1 and theirs is 13.3, so it's a close one.

I have raced a local M3 E46 three times now but I'm running 360 bhp.. First time I was standard 250 bhp and gave him a real scare.. I missed 4th gear too.. I think an S15 with anything from 300 bhp will see one off with out too much drama. Just get a good start and the power to weight ratio will do the rest.. I totally muller him with the 360..I don't run my 15 slammed either let her squat a bit on the rear and she grips loads better.. it's a good feeling..

Plus it depends how good the driver is.. ..
