This is a must-have for ALL BMWs, and simply installs in place of your existing drain plug. With every oil change you perform on your BMW, you'll be able to inspect for metal shavings and debris. Many times, if something is going wrong on your BMW's engine, the magnetic drain plug can give you an early warning. Our championship race team uses this info all the time (Ever find a piece of a valve spring in your oil? We have!) Be sure to get one now, and make the swap next oil change!

When we designed this catch we wanted to have the most function options available, the best separation method, and the easiest to service. The Turner engineered catch cans offer a pre-setup design based ion desired flow direction, however, this does not limit you to this flow. The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle. A 4 chamber system baffle system inside the catch can was 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. Having a closed/recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation.

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.

Design:

Fully TIG-welded 5052 aluminum construction
Brushed anodized finish for a clean look and corrosion resistance
Engineered specifically for M5X/S5X engines in the BMW E30 chassis
Front-sump design clears the factory E30 subframe, no cutting or modification required
Designed and tested in-house by BMW enthusiasts
Features:

Built-in oil control baffles with trap doors to prevent starvation under cornering
Low-profile design for maximum ground clearance - perfect for lowered cars
Billet aluminum oil pickup with integrated stainless mesh screen - fully serviceable
8mm thick flange ensures a reliable seal with OEM gasket
Works with all standard 24V swap motor mounts
3/8" NPT port for turbo oil drain and 1/4" NPT for OBD2 CCV drain
Compatible with G260 and ZF transmissions
Stainless steel dipstick tube (304) included for strength and appearance
Utilizes E36 Dipstick (P# - 11431427993)
Kit Contents:

Turner Fabricated Oil Pan
Billet Rear Mounting Plate
304SS Dipstick Tube with Mounting Hardware
Billet Aluminum Oil Pickup
Optional: Oil Pan Gasket, Oil Filter, and Motor Oil
Optional: Complete Install Hardware Kit
Why It Works:

Direct fitment for M5X/S5X into E30, no cutting or fabrication required
Maximum clearance for front subframe, steering rack, and lowered suspension setups
Track-proven baffling to prevent oil starvation under load
Transmission compatibility with Getrag and ZF gearboxes
Built by enthusiasts, designed and tested in-house on real cars
Please note this will require an oil pump from M50/M52/S50/S52, M52TU, M54, and S54 oil pumps will need to be replaced with a single vanos oil pump.

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.

When we designed this catch we wanted to have the most function options available, the best separation method, and the easiest to service. The Turner engineered catch cans offer a pre-setup design based ion desired flow direction, however this does not limit you to this flow. The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle. A 4 chamber system  baffle system inside the catch can was 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. Having a closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation.

Our catch can was also designed with the idea that the cans fill level can easily be checked with a top mounted dipstick and an optional use bottom drain hole. The drain system comes complete with a valve and hose to be mounted at a lower area of the vehicle so when you're doing an oil change you can drain the catch can.

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
  • Optional use drain hole - drain kit included!
  • Universal mounting kit

One of our most popular items! We have been selling our S14 stroker kit since 1993. Since then we have sold HUNDREDS of this exact kit, and have received incredible feedback from our customers. RELIABLE Horsepower is our goal. Our E30 M3 2.5L Stroker kit uses factory BMW Evolution III parts to convert the stock 2.3 liter engine into the Evolution III 2.5 liter engine. Increasing the displacement and raising the compression yields much more torque: +50 ft/lbs @ 4000 rpm. With a stock head our 2.5 kit will make over 225 hp.

Our kit includes everything you need to convert your 2.3L into a 2.5L. We highly recommend upgrading the intake and exhaust system to allow larger 2.5L engine to breath. Call for more details and for "custom" packages. We can set you up with any other engine components you may want to replace (tensioner rails, chain guides, oil pump, etc) at the same time. For your benefit, we carry all these items (and at a great price).

The Turner 2.5 liter S14 Stroker Kit includes:

  • Genuine BMW 2.5L crankshaft w/ bearings, nut and spacer
  • 2.5L head gasket
  • Bottom end gasket set
  • Turner/Conforti Custom 2.5 Liter Computer Chip **Only available from us! This is what sets our kit apart from the "other guys kit"
  • Wiseco 2.5 forged piston set w/ rings (11.25:1 compression)
  • Genuine BMW rod bolts and head bolts (we suggest Genuine fasteners for reliability)

The timing chain tensioner from the 1995 E36 M3 is a great upgrade for other Motorsport models - 1988-1991 E30 M3 and 1989-1995 E34 M5! This tensioner virtually eliminates the cold start-up engine rattle so common with the S14 and S38 engines. It makes the whole engine quieter and smoother. Any new tensioner will accomplish that but the S50 tensioner has several new features that make it superior to the original design. This unit also has a internally loaded spring, so installation is much easier than the old style tensioner (no need to squeeze the spring and hold it while installing). Includes oil seal ring (not pictured).

This item fits the following BMWs:
1985-1989 E24 BMW M635CSi M6 - M88/3, S38B35 engine
1988 E28 BMW M5 - M88/3, S38B35 engine

Over time, accessory belts begin to wear out and crack. This can lead to the belt slipping, squeaking, or even snapping. Replace your belts and tensioners on a regular basis to ensure you don't end up stranded on the side of the road with a dead battery or over heated engine due to a bit of simple overlooked maintenance. This kit includes all of the items that will need replaced such as the belts, tensioners, and hardware.

Fits the following BMWs:
1984-1991 E30 BWM 325, 325i/is/ix, 325e/es

Often an oversight in maintenance, ignition components are also susceptible to wear and tear. Spark Plugs can accumulate carbon, reducing the spark intensity and it's ability to properly ignite the air/fuel mixture, leading to misfires and generally declining performance. Other ignition components, such as coils, boots, wires, caps, and rotors, can also wear out over time due to factors like heat and contamination, preventing the current from reaching the spark plug.

To start over fresh with all new components, we now offer these Ignition Service Kits. Each kit comes with brand new OE quality components, replacing any potential fault points in your ignition system for peak performance!

See kit contents below for a complete list of included components.

This crank shaft position sensor (CPS) provides the engine computer with engine speed data via the harmonic balancer. It mounts off the engine block and reads the front crank pulley to tell the engine what position the engine internals are in. This sensor is crucial for starting the car as the ECU will not allow the engine to start without this signal. It fits all M20 engines in the E30 and E34. A lot of times the sensor is covered in oil, broken from a spinning belt, or the clearance to the pulley is not correct (should be .040"). Interchangeable with #12141720856.

Brand Options:
Original BMW - more expensive but higher quality and more consistent reliability. The sensor itself has a metal housing that is more durable and will not be affected by heat as much.
Aftermarket/Overseas manufacturer - cheaper than OE BMW but less quality and potentially less consistent. Plastic housing is more susceptible to damage from heat.

This item fits the following BMWs:
1987-1991 E30 BMW 325e 325es 325i 325is 325ix 325ic

Often an oversight in maintenance, ignition components are also susceptible to wear and tear. Spark Plugs can accumulate carbon, reducing the spark intensity and it's ability to properly ignite the air/fuel mixture, leading to misfires and generally declining performance. Other ignition components, such as coils, boots, wires, caps, and rotors, can also wear out over time due to factors like heat and contamination, preventing the current from reaching the spark plug.

To start over fresh with all new components, we now offer these Ignition Service Kits. Each kit comes with brand new OE quality components, replacing any potential fault points in your ignition system for peak performance!

See kit contents below for a complete list of included components.
