Few cars have truly captured the hearts of enthusiasts like the BMW E30 when it comes to automotive performance. The E30 is known for its classic styling and nimble handling, but for car enthusiasts, the E30 is a palette upon which they can paint their automotive dreams. One of the most popular ways to give the E30 a new lease on life is to swap in a new engine, and the 24V M50, M52, S50, and S52 engines are some of the most loved options for doing this. Turbochargers are no less popular in the world of E30 mods, and that's where we come in: DarkLight Fabrication is the go-to shop for making the kind of parts that E30 owners in need of forced induction require—parts like turbo exhaust manifolds. In this post, we'll run down some of the engine choices and other go-faster goodies you can bolt onto your E30.
The E30 Legacy
The BMW E30, manufactured from 1982 to 1994, enjoys a revered status among car enthusiasts. It is known for several key characteristics that predate the current era of turbocharging and the extensive use of electric motors. For one, the E30 is predominantly a naturally aspirated car. If you go looking for founding E30 models, you will find that they are light, RWD (rear-wheel-drive), and well-balanced in terms of chassis dynamics. Naturally, with excellent power-to-weight ratios, the great cars of the E30 line are excellent platforms for performance upgrades. On top of that, they are reliable.
The Allure of the 24V Engine Swaps
1. Power and Performance
The known M50, M52, S50, and S52 engines are known for their impressive power output and smooth delivery. The M50, for example, produces around 189 horsepower, while the S50 can push over 240 horsepower. This power increase transforms the E30 from a fun daily driver to a thrilling performance machine. With the added torque and horsepower, the E30 now has quicker acceleration, improved throttle response, and, just in general, a more engaging driving experience.
2. Modern Technology
Enthusiasts choose to perform these swaps for the advanced technology of the M50, M52, S50, and S52 engines. These engines are designed with DOHC (Dual Overhead Cam) layouts, which promote better airflow and more efficient combustion. Meanwhile, the M52 and S52 are equipped with VANOS (variable valve timing), which allows for better performance at higher RPMs (and at any RPM, really). All of this means more power and torque, coupled with better fuel economy. And it means that the E30 is just a more enjoyable car to drive, both on the street and on the racetrack.=
3. Aftermarket Support
Due to the popularity of the BMW E30 and its compatible engines, there exists a sturdy aftermarket support system. Here at DarkLight Fabrication, we can build you a custom exhaust system, turbo manifold, and downpipe that fit your needs perfectly, whether you've swapped in an S14, an S38, or an M62. We prefer to work with what's called "stainless mild steel," which is a little less corrosive than the regular mild steel most people use, but is still very weldable and workable. For performance parts, beyond what we ourselves can fabricate, there is a wide array of options in the aftermarket, from intakes to ECUs to suspension. And when it comes to the E30 and the M3, the aftermarket parts scene is positively flush.
4. Weight Distribution and Handling
Switching to a 24V motor can also improve the weight distribution of the E30. The inline-six motors are relatively lightweight and can be positioned much further back in the engine bay compared to the stock engines. This shift enhances the car's handling, with sharper cornering and a better overall balance, even compared to V8-swapped E30s. Drivers connected to the cars report a speedier and more enjoyable driving experience.
Custom Fabrication at DarkLight Fabrication
At DarkLight Fabrication, we know there's a wide spectrum of custom automotive work that can and should be done for each individual’s personal vehicle goals. That's why we created a shop dedicated to custom fabrication and making parts for all kinds of performance-driven scenarios.
If a part you need doesn't exist in our catalog or isn't available on the open market, we've got the tools and the know-how to make it for you. That's just one of the many reasons we say with pride that the work we do at DarkLight Fabrication is "tailored to your specific needs." Some of the parts we make include:
1. Turbo Exhaust Manifolds
A custom turbo exhaust manifold is a must if you want to increase the performance of your 24V engine. Our team can design and fabricate a manifold that maximizes airflow and minimizes turbo lag, ensuring that your engine performs at its best.
2. Custom Downpipes
It is essential for well-designed downpipes that exhaust flow and back pressure be improved. Custom downpipes of ours are made to fit flawlessly with the way each customer modifies his or her engine, resulting in not just performance but also sound that is as close to ideal as possible.\
3. Exhaust Systems
Not only does the optimal exhaust system boost performance, but it also changes the auditory character of your E30. We have several different kinds of exhaust systems, ranging from wild race setups that would make even the most cantankerous NASCAR engine weep with envy to systems so refined that they could be mistaken for a street-friendly duet with a tree-hugging acoustic guitarist in a quiet city park.
