We have word that several BMW tuners are working on custom aftermarket performance exhaust components for the N20 engine. The same with the N20 2.0L straight four. However, thus far, the N20 has proven to be a reliable engine without a significant number of common problems. The only problem I had so far is very minor vibration, mostly when I reverse the car (and I intend to have this inspected and adjusted for). We wouldn’t want an F30 328i, F20 128i, F10 528i, or an E89 Z4 Sdrive 28i to go into limp mode on a track day. The N20 4 Cylinder engine replaced the outgoing, less powerful, but more rev happy inline 3.0L 6-cylinder engine, that true enthusiasts will absolutely miss. BMW underrated their turbocharged engine, again, as they did with the N54 twin turbo 3.0L I6 and the N55 single twin scroll turbo 3.0L I6 that powers the F30 335i .

Similarly to the turbocharged N54 and N55 engines that BMW produced prior to the N20, BMW’s stock downpipes result in a major bottleneck for exhaust flow in this section of the exhaust system. Furthermore, we are positive that tuning companies will be able to stretch these figures up to 350 hp and 350 lb-ft of torque without compromising driveability and durability of this engine. The result is increased back pressure. – Ray. The twin-scroll single turbo charger makes it possible for the max torque to develop at just 1,250 rpm without a noticeable turbo lag, which is pretty low in the rev band.

It’s best to stick with industry leaders in tuning, basically the companies that did fairly well in tuning the N55 and N44 engines without causing a disaster for the owners, and without the ECU throwing Check Engine Light (CEL), Malfunction Indicator Lamps (MIL). The 3 series and 1 series BMW’s deserves a gain in engine performance just because the underlying chassis is solid enough to handle the jump in performance without a huge sacrifice in drive-ability. We will continue to monitor upcoming N20 tuning components and post them on this page as they rollout. Although the N20 is a four-cylinder engine, it is considered a replacement for the naturally aspirated six-cylinder N52/N53 because it powers equivalent models, producing similar horsepower to the N52/N53 with greater low-rpm torque and better efficiency.
