Since the introduction of the BMW N54 in 2006, BMW has garnered quite a reputation for squeezing some serious performance out of small displacement inline 6 engines. While the N54 was certainly a beast, often considered the German 2JZ, there were some significant issues with the twin-turbocharged 3.0L inline 6 that wouldn’t be ironed out…
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…
In 2016, BMW made a change to the badging of certain models. Most 28i models began carrying a 30i badge while 35i models went to 40i. These changes occurred at the same time BMW released the new B58 engine. In short, the 340i is simply the newer version of the BMW 335i. Both cars offer…
How much power can the stock N55 engine handle? What are the limits on the BMW N55 block, rods, pistons, crank, etc? These are common questions in the aftermarket world, but there is never a perfect answer. However, there are some general safe limits for the N55 engine. In this article, we lay out the…
We finally wrote some methanol injection guides for the N54 and B58 engines a couple of months back. Now it’s time to show the N55 some love and discuss water-methanol injection. It’s an excellent source of fueling for the N55, and also helps the engine run cooler. There are, however, some risks to running meth…
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…
Our blog has guides for most of the basic bolt-on mods for the BMW N55 engine. We always overlook exhaust upgrades, less the downpipe. There’s a reason we’ve skipped over exhausts, though. They’re pricey for minimal performance gains when you compare exhaust mods to tunes, downpipes, intercoolers, etc. However, aftermarket exhaust setups do have a…
In this guide, we discuss the N55 fueling limits and upgrades available. What are the limits of the N55 fuel system? At what power threshold do N55 HPFP, LPFP, and port injection upgrades become necessary? How does E85 affect the N55 fueling limits? We’ll answer these questions and then some. Additionally, we will list a…
Pro Tuning Freaks (PTF) bootmod3 flash tunes are a popular option for the newer F and G chassis BMW’s. Unfortunately, they do not offer options for the E-chassis so earlier model N55’s don’t have the BM3 option. PTF BM3 offers an excellent web interface and mobile app for easy N55 tuning. Bootmod3 also comes with…
There are so many problems with this topic. For one, the M3 and 335i aren’t even in the same ballpark when it comes to price. The M3 has also been around for decades while the 335i is limited to 2007-2015. For that reason, we’ll narrow this down to the E90 and F80 M3. Another problem…
BMW’s F30 generation includes the F30, F31, and F34 produced from 2011 to 2019. Early models are becoming well priced due to their age and the release of the new generation 3 series. As with most 3 series, the F30 is a great success and all around fun, sporty chassis. Notably, the F30 generation was…
N55 F Chassis MHD Flash Tunes – Power Gains & Info For the most part, this is a similar post to our N55 E Chassis MHD post. However, we split up the posts since the E and F chassis N55’s use different apps from MHD. Additionally, the F chassis N55’s are a bit more capable…
