The No-Compromise Oil Pan for Your 24V E30 Build

Every E30 swap story starts the same way: you want the reliability and power of a modern BMW 24V engine - M50, M52, S50, or S52 - but without heavy modifications or a list of oil pan parts that are no longer available(NLA). You’ve read the forums, seen the DIYs, and done the math. And you’re still faced with the same question: how am I going to find all of these parts and make them work?

That’s exactly the problem we set out to solve.

At Turner Motorsport, we’ve been building BMWs for decades. We've performed the swaps, turned the wrenches, and taken the laps. The Turner Fabricated Oil Pan was born out of that experience, an enthusiast-engineered solution that eliminates the guesswork and lets you focus on what really matters: driving.

We designed this oil pan from the ground up to support 24V engine swaps into the E30 chassis, with zero permanent modifications.

Crafted from TIG-welded 5052 aluminum, this pan is as durable as it is lightweight. The brushed anodized finish adds a subtle shine under the hood and guards against corrosion for long-term reliability. Inside, we’ve integrated full-length oil control baffles with trap doors, ensuring your oil stays where it needs to be, even under the most aggressive acceleration, braking, and cornering.

The low-profile design is perfect for lowered cars, and the 8 mm-thick flange ensures a proper seal with the factory gasket. We didn’t stop there, every pan includes a billet aluminum oil pickup with an integrated stainless mesh screen that’s fully serviceable, a 304 stainless steel dipstick tube, and a billet rear transmission plate that allows you to utilize the lower mounting holes, unlike the stock E34 pan.

Whether you're building a high-performance street car, a dedicated track weapon, or a clean restomod, this oil pan offers OEM-level integration with aftermarket performance. It’s the cleanest, easiest, and most effective way to run a 24V engine in your E30 — built by BMW lovers, for BMW lovers.

Product development:

Our swap pan components are designed, engineered, tested, and quality inspected by our Research and Development team at Turner. Nothing but the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

BMW's newest high-performance powertrain—the S58B30—has proven to be an extremely durable platform built to last! Unfortunately, its factory oil cooler location is an egregious weak link in an otherwise bulletproof oiling system. Positioned just inches above the ground, the engine oil cooler is vulnerable to damage from debris, potholes, parking blocks, and other unavoidable road hazards. A single impact has the potential to rupture the cooler’s delicate aluminum fins and tubes, resulting in rapid oil loss and catastrophic low oil pressure. The only factory protection for this part is a flimsy undertray.

To safeguard the oil cooler, we've engineered a high-strength Aluminum Skid Plate for the F97 X3M and F98 X4M. Designed for peak performance and protection, our skid plate acts as a shield, preventing damage to the oil cooler while maintaining proper cooling efficiency.

Crafted from 4GA (4.83mm) 5052 aluminum, our skid plate delivers a perfect balance of strength and weight savings. Unlike the fragile factory plastic belly pan, our design forms a protective barrier from the front bumper to the front subframe, shielding your oil cooler and other fragile componentry from unexpected impacts. Its sturdy one-piece design enhances underbody rigidity without adding unnecessary weight over the front axle.

At Turner Motorsport, we believe protection shouldn't come at the cost of performance. Our engineers aimed to outperform the factory undertray design with laser-cut air channels that optimize airflow through the oil cooler. While located under the engine, the oil cooler receives its fresh airflow from the front air dam. Air flows through the lower front grille, into the oil cooler core, and out of the skid plate. The factory belly pan allows air to bypass the core, leading to inefficient cooling and mediocre airflow at speed. Our design allows for efficient heat dissipation by incorporating flared air channels, which guide cool air through the oil cooler and deflect road debris before it can reach the fragile core.

Upgrade your F97 X3M or F98 X4M with the Turner Motorsport Aluminum Skid Plate for added protection, durability, and performance.

Modern day emissions regulations require the use of a closed crankcase ventilation (PCV) system to recirculate combustion blow-by gases from the crankcase back in to the intake to be burned.  Unfortunately, these blow by gases contain water vapor (which is a byproduct of combustion) and pick up oil mist from and the windage cloud and cam lubrication system as they travel through the crank case.  Due to less than 100% effective air/oil separation in the stock PCV system, some oil mist and water vapor gets carried back to the intake tract and over time cause oil deposits in the intake manifold, intake ports, and on the back of intake valves.  All will eventually lead to poor performance and reduced fuel economy, and the presence of this oil mist in the intake charge may even increase the risk of engine-damaging detonation. 

With forced induction, track use, and/or extended high RPM usage, these symptoms increase as the factory PCV system is overwhelmed, and a catch can becomes a must for your E46 M3. This kit is a direct fit making this an easy reversal if desired as well as maintaining a clean appearance by utilizing the open "smuggler's compartment" on the passenger side of the engine bay.

Features:

• 6061-T6 billet machined body, anodized black for lasting protection and appearance
• Strategically positioned 4 chamber baffle system maximizes oil / air separation 
• Knurled and black anodized oil dipstick makes inspecting oil volume of reservoir clean and simple
• Sealed with a pre-installed viton o-Ring
• Includes 2.5mm allen key to remove baffle plates for cleaning
• Engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can
• Closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation
• Valved drainage system - no removal of can necessary to empty

The N54 suffers from a weak point in its crankshaft. It has been reported that when increasing the power to the engine, the crank hub can move or spin slightly under an extreme load. This is most apparent under high-rev downshifts or in the case of increased boost pressure which creates more stress on the engines rotating assembly. In order to keep this from happening, the crank bolt must be secured to the hub to keep it from backing off, but this can be a tricky solution since a simple dab of Loctite will not suffice. 

Here is an easy, and cost-effective way to secure the situation; The VTT N54 crank bolt capture. This lightweight and durable ring slips over the head of the crank bolt fully encapsulating it, and locks it to the crank hub and eliminating its ability to spin. The VTT-CBC is 100% Billet Aircraft Grade Aluminum, Anodized black to protect it from the elements, and give it a stealth look. What's more is that it weighs only 1.3 Oz's meaning you aren't adding excess mass to the crankshaft which will avoid any imbalance or vibration issues.

While this is not a full fix for all crank hub spinning issues, the engineers at Vargas have found most issues have stemmed from the bolt itself backing out, and this is a great way to keep that from happening. Extremely lightweight at only 1.3 Oz's it adds virtually no weight to the crank which is important for balance and vibration.

Kit Includes:

• 1x Aluminum Crank Bolt Capture
• 8x Fasteners Gr. 12.9
