Check out our N54 content ranging from common N54 engine problems to N54 port injection guides and everything between. Don’t miss our upgrade guides: Upgraded twin turbos, single turbo upgrades, downpipes, inlets & outlets, and more.
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…
It’s about time we got around to writing a water methanol injection guide for the BMW N54. WMI is an excellent source of fueling for the N54, and comes with the added benefit of cooler intake temps. However, there are also some risks and things to consider prior to opting for methanol injection. In this…
This post will serve as a complete guide to N54 stock fueling limitations and upgrades available. What are the limits of the stock N54 fueling system? At what power do N54 LPFP’s, HPFP’s, or port injection become necessary? How does E85 factor into all of this? We plan to answer all of these questions and…
We’ve written guides for many N54 bolt-on parts, but always overlook exhausts. That’s in part due to the underwhelming performance gains when compared to a tune, catless downpipes, etc. However, aftermarket exhaust set ups do have their benefits – sound and looks. In this guide, we will discuss some of our favorite exhaust set ups…
Unfortunately, the 135i and 335i powered by the N54 received open differentials from BMW. It’s a serious limiting factor for those looking to make more power and/or track their cars. A limited slip differential is an excellent mod to help put more power down. In this guide, we will discuss limited slip differentials (N54 LSDs)…
We’re finally getting around to writing about upgraded N54 inlets and outlets. Oddly, they’re mods we often overlook despite running upgraded inlets and outlets on our 2007 335i. Inlets and outlets are also some of the best mods for the N54. Turbo inlets are the intake pipes that run from the intakes to the turbos….
These posts are challenging to write because best is subjective. Spoiler alert – we’re not going to say one year 335i is better than another. We’ll break down the differences by year and allow the reader to decide. How to Pick the Best 335i For You Before we dive into a year-by-year breakdown let’s touch…
Some refer to the BMW E90 (E9x) 3 series as one of the last great true drivers cars from BMW. The preceding E46 chassis was so good and left the E90 with big shoes to fill. Initially, many didn’t believe the E9x chassis to be as good. However, with newest E46’s nearing 15 years old…
We know, we know. The title of the site is not going to help plead our case. Regardless, we will do our best to make this an unbiased comparison. It’s true – we love BMW’s because we believe they’ve built some of the best inline-6 turbo engines ever. We also believe the N54 is an…
In this article we will aim to have some fun and showcase unique sounds of the N54 engine. The N54’s reputation in the tuning world has led to a large aftermarket scene. You’ve got massive single turbos revving to 8k RPM’s to almost stock N54’s with loud exhaust, and everything between. N54 pops, burbles, flames,…
In this post, we will cover several common fault codes for the BMW N54 twin-turbo engine. These codes apply to the 135i, 1M, 335i, 535i, X6 and Z4 powered by the N54. Additionally, certain fault codes may apply to various non-N54 engines. If you are looking for more detailed information about some of the N54…
