BMW Engine Parts for BMW 3 Series E30 (1984-1991)

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.

If you're experiencing hard starting, flaky charging, or other electrical issues, your engine ground strap may be the culprit. On older BMWs, the engine ground strap is a thin, non-insulated cable that spans from the engine mount arm to the frame horn. Despite the seemingly simple nature of this part, on older cars, it is known to cause massive headaches. Due to its non-insulated design, years of exposure to water, dirt, and road salt will cause the wire to corrode, ultimately leading to complete failure. A break in this cable will cause an open circuit, resulting in issues with the vehicle's electrical system and potentially leading to a no-start condition.

To solve this issue, ECS has engineered an exact-fit, upgraded ground strap for your BMW! Unlike its OEM counterpart, this design features insulated, large-gauge copper wire for dependable conductivity and long-lasting durability. Additionally, factory-style lugs are zinc-coated, crimped, and soldered, ensuring protection against corrosion and oxidation.

Whether you're replacing a visibly corroded strap or proactively preventing failure, this solution from ECS is sure to provide lasting performance and protection.

These WPC-treated bearings are the best we have seen! WPC is a shot-peening treatment at a microscopic level. It's perfect for sensitive surfaces like bearings. The WPC treatment removes imperfections and high spots, while creating a surface that retains oil better than the original surface. This greatly reduces friction. The bearings in this kit are original equipment KS bearings that are sent to WPC for treatment. The treated bearings are stronger with less metal fatigue and less friction than buying off-the-shelf bearings from the dealer.
