BMW’s N20 engine featured in the 228i, 328i, 428i, 528i, as well as other 28i variants, did not built up the greatest aftermarket and tuning reputation, as the engine has been touted as fragile. Although the N20 is not the strongest motor there is still plenty of power to be unleashed with a tune and…

The B58 is the successor to the N54 and N55 engines, both of which were highly tune-able and able to make lots of horsepower with only a handful of supporting mods. The N54 takes the cake in regards to horsepower capabilities, but it had many engine problems as a result. The N55 platform was made…
Front mounted intercoolers are extremely important applications on turbocharged cars. Intercoolers cool the compressed air created from the turbochargers, reducing the temperature and increasing the density of the air that is fed into the engine. Cooling the air makes the air more oxygen rich, therefore improving the combustion in the engine by allowing more fuel…
Why Upgrade my N54 Downpipes? One of the biggest restrictions on the N54 powered 135i, 335i and 535i is the factory catted downpipes. Downpipes bolt directly to the turbochargers and the factory catalytic converters create significant back-pressure which results in slower turbo spool. Modifying your N54 with catless or high-flow catted downpipes results in faster…
The BMW N54 engine featured in the 135i, 335i, and 535i is one of the most tune-able engines ever. Some people call it the ‘2JZ’ of German engines, but we think the N54 is on a whole new level. The N54 engine has forged internals, meaning it can handle an immense amount of power without…

The N54 is a very strong production motor that is restricted by the low-boost setting of the stock tune. Due to the n54’s capabilities there are no supporting modifications required despite a tunes ability to increase horsepower and torque by nearly 100 over stock. However, there are a few minor maintenance items that should be…
