European tuner Kelleners begins work on the new BMW N20B20 turbocharged four-cylinder engine. The 2.0 liter unit offers 184 and 245 horsepower in standard form. The lower-powered unit is used in the 120i, X1 20i, X3 20i, 520i and Z4 sDrive20i models.

The more powerful powerplant is used under the hood of the 528i and new 328i models.

Kelleners ups the power output to 220, respectively 294 horsepower for the more powerful four-banger. The torque was also increased from 270 Nm to 324 Nm, and 350 Nm to 420 Nm.

The 294 hp and 420 Nm brings the performance of the 2.0 liter four-cylinder close to the 3.0 liter TwinPower turbocharged inline six-cylinder.

The impressive power upgrade is implemented with performance tuning modules that are connected to the original BMW connectors of BMW. Kelleners has not released the pricing for the power upgrades.

In addition, Kelleners achieved another impressive power increase for the BMW 1 Series M Coupe which now outputs 420 horsepower and peak torque of 590 Nm.

    It’s not that impressive. why? because Inside Line dyno’d a Z4 28i and the result was 230whp which is about 270hp at crank. a 20hp gain with these new turbo motors is super easy, just raise the boost. if the tiny turbo get maxed out, add a bigger catless downpipe and again you will gain more.

      until it blows up :-)  back in 1984 had a friend with a audi quattro 2.0 turbo engine (220HP from factory).  he did just that. kept raising the boost, larger turbo, lowering the exhaust resistance, pushing more air, larger intercooler, etc. etc. he reached about 380hp and then one day it went kaboom… sadly the car ended up on a junk yard. it was a great car but a crazy owner.

        Really, BACK IN 1984? That’s your reference point or limit of experience? Wake up, things have changed. You are a very ignorant person.

      Recommend you educate yourself about the BMW twin turbo syste, Sound like you are more experience with the US OEM stlye single turbo set ups where a simple pulley change is all you need to easily run the boost up 5 to 10 pounds and live with few mods. You also need to read the follow up on the dyno claim as it was later found to be in error.

    just wait for the JB to arrive they will make way better boost

    Is that the main ECU on top of the manifold? I do not think so; it may be some other part of the ECU.

    I don’t think it’s hard to crank a turbo engine up to any hps’. The trick is to keep it balanced and driveable. Also to maintain a good life expectancy.

    • LaMa

      Yes, its true. The gain is only gain until it blows up the engine. I would be hesitant to use anything else with these new engines but factory or maybe Dinan.
      The S54 engine was strong and could take a huge boost, 600-700HP was possible and still remained reliable. Newer engines are made for the factory ratings and not much more.

      Plus more power does not always equals more fun. If the power comes at the expensive of a low end torque then the car will be track friendly street horror.

        Are you really as ignorant as you sound? My S54 M Roadsgter was the best BMW I’ve owned but it could not take “huge boost,” without significant modifications. Active Autowerk was one of the few to successfully turbo the S54, Even DINAN avoided aS54 turbo. “Newer engines are made for the factory ratings and not much more. ‘Newer engines are made for the factory ratings and not much more. “Wow, amazingly stupid. OEM motors are mad for specific purposes be it fuel mileage, hp or endurance. But they also have to build them to last even beyond the warranty period or they get a poor reputation. BMW motors conservatively rated but also a bit harder, compared to an LS Chevrolet, to get more power from. The main factor is cubic inches. And the old adage is still true that you cant beat cubic inches. When it takes a turbo to make 250 hp in a 4 cyl 2liter, you can buy over 300 hp in a 3 liter V6 in any Ford or Chevy with NO boost.
