E90 / E92Model Year: 2007 - 2013. E46Model Year: 2000 - 2006. M4. The day I brought her home: 2009 E92 M3, Alpine White, 6-speed manual, carbon fiber roof, Black If you put 89 in, the car would sense that and pull back timing to avoid detonation. It follows, then, that if the car detects higher octane gas (to an extent), it will advance timing. From what I've read, the optimal octane for the stock tuning is 94, after which additional octane becomes counterproductive unless, as you say, the car is tuned Driveshaft- you need a manual driveshaft, the 6mt shaft is 1433MM and the DCT shaft is 1456mm. Differential - Manual diff is required or the car will be very lazy. Manual ratio is 3.85, dct is 3.15. Wiring - as far as the wiring goes, you need to get a manual transmission harness, this is still available new from BMW for $164. That's not an LCI, that's a modded headlight. The LCI only updated the tail lights for the M3. The regular 3 series got upgraded headlights as well, but the M3 did not. The stock M3 headlights are the same from '08 to '12. Cool. I've not seen anyone retrofit a LCI headlight into an M3. After the dyne tune the car made 313 horsepower to the wheels and 256lbs-ft of torque at the wheels. The e92 still beats the e46, but only by about a fender or so now. The margin seems to depend on the speed the roll begins at. Higher the speed the greater the margin of victory for the e92. E92 m3 manages it in 5.3 seconds, and given its age I imagine it's lost a little bit of that. 340i does it in 5.2, 335D will do it in 4.8 so half a second faster than the m3. Also manages to get 40mpg which is a nice bonus. 1. sph666 M2 F87 • 6 mo. ago. Buying used E92 M3 as daily driver. Being new to the M3 world I must say I always lusted after the mighty V8 of the E9x the moment I saw the first BMW video of it ariound the Ascari track. Now that used car prices of the E92 are down a bit and the mileages are around 75k km for these 2007 models I became increasingly interested Years. 2006-2016. Configuration. Straight-6. a key reason why the E92 M3 is a favorite as a driver's car. It packs a punch with a rating of 414 hp and 295 lb-ft, but power was not its biggest FdIuQ.
