BMW Drivetrain Parts for BMW E30 M3 S14 2.3L

Vague or slopping shifter feel even after installing a short shifter or new OE shifter linkage bushings?  Looking for a more precise shifter feel in your classic BMW?  Consider replacing your old, worn rubber rear shifter bushing with new Turner poly to get the best shifting experience possible!  The Turner engineering team wasn’t satisfied with the other options on the market, so we set out to design the best solution for ease of installation and performance.

The competition requires the installer to cut or burn the rubber bushing out of the stock housing to be able to install their poly bushing, requiring reuse of an old worn out housing, or buying a new costly bushing assembly.  We decided this was cumbersome and unnecessary, so we designed a complete upgrade replacement bracket with a 70A polyurethane bushing preinstalled for a quick bolt-in installation.  Our bracket is precision formed with a CNC machined and TIG welded bushing cup to perfectly match the OEM bracket, and is made from 304 stainless steel for exceptional corrosion resistance.  The result is a complete design solution that creates much crisper shifting with nearly zero added NVH for a more engaging and enjoyable driving experience.

Note: Some shifter arms have a mushroom-shaped end. Use extra care installing our bushing on these arms. Filing this mushroom down makes installation easier, however simply applying sufficient pressure to the back side of the bushing during installation will allow this bushing to install smoothly.

This is the last bushing you will ever want or need for your E28, E30, or E34!

Product Features:

• Pre-installed bushing, NO cutting or burning for installation
• Corrosion resistant 304 stainless steel mounting bracket
• 70A durometer poly bushing for reduced NVH
• Ready to install out of the box
• Replaces Genuine BMW part number 25111220707

Designed for track drivers, drift enthusiasts, and drag racers alike, this all-in-one driveline upgrade eliminates the factory weak points and reinforces your drivetrain for high-performance abuse. Whether you're laying down 500HP, clutch-kicking through corners, or launching hard at the strip, this cover keeps your differential secure, cool, and ready for battle.

The stock E30 differential cover features a single mounting provision—fine for a stock M20, but guaranteed to fail on your boosted high-horsepower M5X build. After years of broken covers, mounting tabs, and dreams, our team of E30 enthusiasts engineered the ultimate fix.

Unlike the brittle OEM cast aluminum cover, our upgraded differential cover is CNC-machined from 6061-T6 billet aluminum, offering a 30% increase in material strength alone. More importantly, a secondary mounting ear has been integrated into the design for added support, drastically improving stability and driveline shock absorption. The secondary mount is tied into the chassis using a reinforced sheet metal bracket and a billet aluminum plate, allowing for bolt-on installation or welding for ultimate rigidity.

Another major flaw of the factory E30 differential cover is its lack of any cooling provisions, leading to overheated fluid and premature wear. Our engineers solved this issue by incorporating advanced cooling features into the design. Large external fins have been added to the cover, and are optimized using CFD (Computational Fluid Dynamics) analysis to efficiently dissipate heat, reducing overall fluid temperatures. By maintaining a more stable differential temperature, this cover ensures consistent performance and extends the lifespan of your differential fluid. A built-in air duct assists in cooling by increasing airflow around the differential, further preventing heat-related failures. Our cover features optional -6AN fittings, allowing for easy integration of an external fluid cooler if desired. Finally, a 1/8 NPT port is included with the kit to ensure compatibility with fluid temperature monitoring systems.

Precision-machined from 6061-T6 billet aluminum and finished with a black hard coat anodizing, this cover is built to withstand hard use. Despite its robust construction and superior durability, this differential cover retains factory mounting features. This means any E30 188mm differential cover bushing can be installed, allowing you to tailor our upgraded cover to your build. The cover also accommodates large rear sway bars, ensuring fitment on cars with upgraded suspension. Our proprietary removable air duct provides easy access to sensor bungs, fill plugs, and drain plugs, making differential service a breeze.

FEATURES

Some modifications to your vehicle may not produce power to create gains in the overall performance of your driving. When you add a "Po' Boy" clutch stop to your BMW the performance gain is directly felt in the driving experience.

The ECS clutch stop allows the driver to fine tune the position of the clutch pedal to closely match the engagement point for precise, quicker shifting. The adjustment range found in this product can be set to the stock engagement point or can be adjusted to follow the wear of the clutch.  Meaning your new experience will never change all the way to the end of the clutch life and can be reset to enjoy the next clutch.

Note: This modification might require some slight modification to the clutch switch mounting bracket, which can be bent slightly by hand.

The ECS Billet Master Cylinder Fitting is the ultimate solution for a notorious failure point in BMW E30 clutch systems. This critical fitting, located at the end of the master cylinder reservoir hose, is responsible for delivering hydraulic fluid to the clutch master cylinder inlet. Unfortunately, the OEM plastic fitting is prone to degradation after prolonged exposure to brake fluid, often leading to total hydraulic pressure loss and brake fluid leaks inside your vehicle.

ECS has addressed this issue by engineering a robust and long-lasting alternative. Crafted from 6061 billet aluminum and finished with black hard-coat anodizing for superior corrosion resistance, this precision-machined fitting replaces the fragile plastic original, ensuring leak-free performance for the lifetime of your vehicle. Upgrade to our Billet Master Cylinder Fitting during your next clutch master cylinder service and enjoy peace of mind knowing your BMW is equipped with a durable, high-quality solution.

Features & Benefits:

Made from 6061 billet aluminum for a permanent, reliable upgrade over the factory plastic fitting. Black hard-coat anodized finish ensures long-lasting protection against the elements. Precision-machined barbs match OEM dimensions for a leak-free seal with Genuine and aftermarket master cylinders. Designed for a secure fit within the factory grommet location. Prevents brake fluid leaks and loss of clutch hydraulic pressure caused by plastic fitting failure. Upgrade your BMW and bulletproof your master cylinder with the ECS Billet Aluminum Master Cylinder Fitting. Ensure clutch hydraulic system reliability and enjoy peace of mind knowing your failure-prone plastic master cylinder fitting has been addressed.

A common source of leaks, the selector shaft seal should be replaced whenever the shifter assembly is serviced to prevent fluid loss.

Fits the following BMW chassis:
E36, E39, E46, E36/7 Z3
