Exclamation Hell Yes, the BMW N20 Engine is Tuneable Says Kelleners with 294 HP / 310 LB-FT Tune

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, 528i, Z4 sDrive28i, and upcoming F30 328i), while having better fuel efficiency.

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.

The Kelleners N20 tune achieves 294 hp and 310 lb-ft torque (420 Nm), a +49 hp and +52 lb-ft gain over factory quoted figures. See the full specs below:

On the X1 sDrive20i/xDrive20i, X3 xDrive20i, 520i, F20 120i and Z4 sDrive20i models (which get a lower powered N20 configuration from the factory):

These power figures were achieved with their tune only and no other modifications. No doubt we'll see more aftermarket tuners releasing their N20 tunes, especially as the F30 328i hits the market.

Nohhhhh, no way I'll be very suprised if it is, still great gains though....!

240hp to 294hp = 54HP
260tq to 310tq= 50tq

Good numbers.

Nice. Those are some decent gains it'll give a normal 35 engine a run for it's money. Imagine a down pipe, exhaust and intake. I can see this motoring handle 350 hp with full bolt on.

makes me to seriously consider 328i instead of 335i... but lets wait until what kind of beast is to be unleashed in the next 335i.

I will gladly purchase a 328i over 335i. Single turbo 4-cylinders are a lot of fun. Something is very satisfying squeezing big hp out of 4-cylinders.

With a bit more tuning, I won't be surprise to see +100hp/100tq.

That's great news considering the car from factory is about 11k less
then the 335i which is pushing 306hp/300trq. That's means with one simple tune it may even be better and faster
