Intake upgrades are one of the most common engine modifications for good reason. They’re cheap, simple, and effective. While the S58’s factory intake system is efficient at stock boost, it becomes restrictive as you begin adding power and boost. It’s easy to understand why it becomes restrictive as the 3.0L twin turbo inline-6 is able…
It’s no secret that the 3-Series chassis is a fan favorite for budget track car builds. With other 3-Series options climbing in price to a ridiculous degree, the E46 chassis remains one of the most affordable options for someone looking to have some fun on the track. E46s are also well-balanced, produce ample power, and…
So you want to build an E30 track car, huh? Well, I don’t know you personally, but that might be the best idea that you’ve ever had. From a fun-per-dollar perspective, anyway. The E30 is truly one of the best possible chassis to transform into a certified track classic. Lightweight, direct, and communicative, agility is…
I briefly discussed water-methanol injection in this BMW B48 fueling mods guide. Methanol is a high-octane fuel with similar benefits to E85. However, it’s too lengthy of a topic to cover in-depth in the fueling guide. As such, I am writing a separate article to fully examine B48 WMI including benefits, risks, costs, and more….
The B48 2.0L inline-4 has a very capable fuel system from the factory. However, once you begin pushing for more power, it becomes important to run higher octane fuels – like ethanol – that may necessitate upgrades. Some of the best B48 fueling upgrades include port injection, HPFP, injectors, and WMI. In this guide, I…
It’s no secret BMW has made some excellent, fast high-performance cars. However, BMW has mostly kept away from horsepower wars, and has instead relied on building “The Ultimate Driving Machine”. Often, it’s about the handling and overall driving experience over pure power and straight-line speed. That doesn’t mean BMW hasn’t built some incredibly powerful engines,…
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…
One of the first roadblocks to making massive power from the BMW B58 straight-6 is the factory high-pressure fuel pump. While the factory B58 high-pressure fuel pump is a pretty capable piece of kit compared to the HPFPs found on older BMW turbocharged engines, it still taps out at around the 450whp mark on 93…
Most engine and car performance upgrades begin (and often end) with an ECU tune or remap. This is considered a cost-effective method of gaining horsepower and torque. What’s more, the same procedure also helps to increase fuel economy. The good news is that this is perfectly legal and only takes about half an hour to…
The BMW F30 is the sixth iteration of the notorious BMW 3-Series. Released in 2011, the F30 chassis replaced the E90 3-Series which was unquestionably due for a refresh. With the introduction of the BMW F30 came a number of firsts for the 3-Series chassis and BMW as a whole. The F30 range was the…
The BMW F30 is the sixth generation 3-Series and one that is starting to see a massive amount of aftermarket support now that it has been around for over a decade at this point. Compared to the E90 3-Series that preceded it, the F30 had a noticeably better fit and finish. Not only did their…
Engine fault codes are also known as a diagnostic trouble code – or DTC for short. These codes help point you in the direction of any potential issues with the engine. If you own a car for the long-run then chances are you’ll run into at least a few fault codes along the way. BMW…
