Alpina, the BMW tuning specialists, has released and revealed the 2012 Alpina BMW B3 GT3 E92 at the 2011 Tokyo Motor Show. This model will be a special production run limited to just 99 units.

The B3 GT3’s B3 S Bi-turbo motor is good for 408hp and 398 lb-ft torque. It’s paired with an Akrapovic titanium rear silencer. All this propels the B3 GT3 from 0-62mph in just 4.6 seconds.

Missed the 2011 SEMA Show in Las Vegas? No worries, Johnny Lin provides us with a mega gallery of BMW models at the event (along with some other fine looking German vehicles). Hope you got the bandwidth to keep up =)

BMW’s new 2.0L 4 cylinder turbo engine (the “N20″) may be down on cylinders and displacement compared to the inline 6 cylinder (N52) that it replaces across BMW’s model range, but even in factory form, it matches the outgoing N52’s horsepowers and features an extra 30 lb-ft of torque (in the X1 xDrive28i, X3 xDrive28i, F20 128i, 528i, Z4 sDrive28i, and upcoming F30 328i).

And what the N20 loses in smoothness and top-end pull compared to the outgoing N52, it now looks like it will easily make up for in tuneability. Kelleners Sport has released the specs of its N20 tune and the figures are impressive! These are power gains that the naturally aspirated N52 could never achieve.

Here’s one of the first reviews of the BMW 335i Performance Edition Retrofit Kit, which is a factory tune which retains the factory warranty. Horsepower increase from 300 to 320, torque increase from 300 to 317ft-lbs for a manual transmission, and to 332 for automatic transmission. This all results in 0.2 seconds faster acceleration time than the standard factory model from 80 to 100 km/h and 0.5 seconds faster acceleration time than the standard factory model from 80 to 120km/h. The Performance Edition Kit can also be retrofitted on the 135i.

This may not be the very first 3-series to M3 conversion we’ve had on BIMMERPOST, but M3 conversions are always unique and interesting to see. This particular build features a beautiful custom Ferrari Girigio Silverstone paint and several other custom touches. It was recently featured in BMW Performance Magazine, so check out the build details and photos inside.
