Spark plugs are standard maintenance on the BMW N54, and it’s equally important to address spark plugs when modifying the engine. The spark plugs are often a source of issues and headaches from misfires. As such, it’s important to install the right spark plugs with proper gapping (and replace them as normal maintenance). In this…
Upgrading the N54 turbos isn’t a decision that most of us take lightly. It can be a serious financial commitment, and you want the money to feel like it was well spent. I know I personally spent a couple weeks deciding between N54 single vs twin turbo upgrades. Once I decided on twins, I then…
The BMW N54 engine is widely seen in the BMW community as a toxic lover. When it’s going well it’s going great, however, the N54 can deal some pretty devastating blows too. While the BMW N54 is considered one of BMW’s most modifiable and power-capable turbocharged engines, it does come with its fair share of…
Every BMW enthusiast at one point has heard the argument, “BMWs are just an expensive way to lose even more money.” BMW has developed a stereotype among the misinformed or uninterested crowd as being unreliable and overrated. But, those in the know understand that that isn’t really the case. Sure, BMW has released some…temperamental engines…
We often find ourselves writing about the twin turbo 3.0 inline-6 BMW N54 engine. It’s a true gem for several reasons; N54 powered cars are cheap, fast, and easy to mod. However, there is a popular belief that shines true. Fast, cheap, reliable – pick two. It’s no secret that the N54 is NOT a…

Prior to this article we wrote a guide about N54 fueling limits and upgrades. However, we didn’t dive fully into port injection (PI) since there’s a lot that goes into these setups. Those familiar with the N54 platform likely have some idea about port injection. It’s the ultimate fueling solution for those looking to make…
BMW N54 engines have long been known to deliver great performance with a few basic bolt-on mods. Simple bolt-ons for the N54 can push the engine to 400-450+whp with relative ease. Downpipe (DP) upgrades are among the best mods to take the 3.0L twin turbo engine to the next level. In this guide, we compare…
The BMW 1-series made its initial debut in 2004 in the form of the E87 5-door hatch. It wasn’t until 2008 that BMW brought the 1-series to North America as the E82 coupe and E88 convertible. Models include the 128i, 135i, and legendary 1M. We’ll make reference to some foreign models, but this article is…
We believe BMW did an excellent job with the E90 and E92 chassis. They might not be the lightest cars compared to the previous 3 series models. However, the E9x chassis offers great balance and the power steering feels flawless. Of course, with most E90 and E92’s nearing or surpassing a decade old a lot…
How much power can the N54 engine handle in stock form? What are the limits on the N54 block, pistons, rods, etc? These questions come up frequently, but there is no perfect answer.

A charge pipe (CP) is an excellent early mod to knock out on your BMW N54. It’s not so much for the performance benefit as it is for the peace of mind. The stock N54 CP is plastic and is prone to cracking under higher than stock boost. Chargepipe upgrades also allow the option to…
