BMW N54 Tuning & Maintenance Guide

In the past few years the N54 twin turbo 3.0L Inline-6 has gained the reputation of being an easily tunable and powerful engine. With the N54 aging and the increasing number of modifications available, we are bound to begin seeing more blown engines and turbos. Although the block and internals are very strong, the N54 is prone to issues without the proper maintenance and repairs. Whether your N54 is stock or running a large single turbo set up, this guide will ensure your engine is running at its best.

BMW M50-M52 Intake Modification

With this modification, your M52B25 or M52B28 engine will make more power.

The M52B25 and M52B28 engine can be found in the E36, E39, E38, and in some early BMW E46 models.  It is not the easiest modification, but if you are at least a little handy, it is not difficult.  Some people say that this will gain an additional 20HP, while some say it won’t give you any.  I believe that there are power benefits.

In the picture below, you see on the left an M52 intake, and on the right, an M50 intake.

Diederik’s E36 323i Coupe

My name is Diederik, 21 years old and I am a mechanical engineer student with a passion for cars.  When I was searching for more information about the BMW E39 M5 I found this website and registered myself for the future.
At the moment I drive a BMW E36 323i MT coupe in Hellrot with some modifications and a Volvo 855 Turbo AT in Beige Metallic. Continue reading

BMW E36 Bi-Xenon Headlight Retrofit

thumbHow do you get high intensity lighting for under $200 $50?

Easy, peasy, lemon squeeze: all you need to do is retrofit your stock plastic lens E36 headlights with bi-xenon projectors.  With some modification from a Dremel, razor blade, and a pry tool, you too can have HID lighting without resorting to a eat-ramen-every-night college-esque budget.   Continue reading

Alex’s 2000 328i Introduction

IMG_3171

If I were to tell you that I’ve always been a fan of BMW, I’d be lying.  Two years ago, if you were to tell me my first car would be an E46, I would have called you crazy!  Living in Buffalo, NY, I pictured my first car as some sort of all wheel drive vehicle.  I really was set on an older WRX, due to the decent performance, and great all wheel drive system.  I was also your typical Fast and Furious type kid who drooled over JDM “riced” out cars.  It’s bad, I know.  Luckily, one trip to visit my brother in San Francisco changed my taste in cars completely.

BMW E39 SIRIUS XM, AUX Input, BM53 Radio Retrofit DIY

IMG_3169Welcome to what is going to be a very long article, and a great wealth of knowledge.  I am going to attempt to break down exactly what you need to do to retrofit a BM53 Radio, Auxiliary Input, and SIRIUS XM Radio into your BMW E39 5-series.  It is important to realize that the BMW E39 uses an infrastructure for technology in the car known as I-Bus, or Information Bus.  Picture it as the platform, and the language of hardware/software that makes everything technology communicate.  I-Bus was first used on the 1989 BMW E31, or 8-series.  It offers an impressive data transfer rate of 9.6KB/s.  I-Bus was used until 2006, on the E46 3-series and E53 X5-series.  This gave BMW a long time to create newer, better, faster, and more functional hardware that operated off of I-Bus.  Note that many BMW models used I-Bus, but the majority of these are not compatible with the products listed in this article due to their age.  The oldest car that I would expect to work with SIRIUS XM, for example, would be a navigation equipped E38 7-series.

BMW’s Bastard Child – The Intro of my 318ti

318ti Exterior

Let’s keep things short, and get this started. I sold my E39 M5 at a good price, but I still miss it dearly. I’m in college studying engineering and pre-med, so I’m going to be in school for a long time. I don’t have the time anymore for photo shoots, car washes and detailing all the time. I needed something cheap, reliable and plain; and it had to be a good project car for some great E39Source content. I decided to buy a Ti – it’s a big F-U to all the viewer’s that thought I was going to get something flashy, and worst of all, everybody hates how it looks. Continue reading
