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).

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.

The Schwaben Piston Ring Filer is a vital tool for obtaining the precise end gap necessary for optimal piston ring performance.

This filer allows you to swiftly and accurately file piston rings to exact measurements, enhancing your engine’s efficiency and lifespan. By simply positioning the piston ring and turning the handle, you can easily rotate the abrasive wheel for a smooth and effective filing process.

**Note:** For the Schwaben Universal Piston Ring Compressor, check out T25805755!


Key Features:

  • Optimize Performance: Achieve the perfect end gap crucial for top engine efficiency.
  • Quick and Precise: File rings to exact specifications with ease.
  • Easy Operation: Position the piston ring and turn the handle to effortlessly rotate the abrasive wheel.
  • Enhanced Engine Longevity: Accurate end gaps contribute to longer engine life and better performance.


Instructions:

1. Position the Ring: Place the piston ring on the outer edge against the stop and align the ends squarely against the grinding wheel. Apply light, even pressure against the wheel to prevent grinding too large a gap.
2. Operate the Tool: Turn the handle so the grinding wheel turns towards the inside edge of the ring (counter-clockwise when viewed from the handle side of the tool).
3. Exercise Caution: This is a diamond grinding wheel. It cuts fast!

Checking Piston Ring Gap:

1. Deburr the Ring Ends: Carefully remove any burrs on the ring ends before placing the ring in the bore. A light touch with a fine abrasive stone works well.
2. Clean the Rings: Thoroughly clean the rings with lacquer thinner or acetone, as the paint coating from the factory may occasionally scratch the cylinder bore. Always wear gloves during this process.
3. Position the Ring in the Cylinder: Place the ring squarely in the cylinder bore, about 1" down from the deck surface. An upside-down flat-top piston will help you properly square the ring.
4. Measure the End Gap: Use a feeler gauge to measure the ring's end gap. Apply light grinding pressure and check frequently to avoid making the end gap too large.

For optimal valve train performance in your BMW, replace old rockers when shaft/rocker clearance exceeds specifications. When installing a new cam or rocker shafts, it's recommended to re-machine rocker pads or replace rockers to ensure maximum valve train life. The kit includes rockers and provides benefits such as:

  • Replacement for old rockers with excessive clearance.
  • Ensures maximum valve train life with new cam or rocker shaft installation.
  • Rocker bushings may need honing for proper clearance.
  • Careful inspection of rocker shafts for even wear and replacement if necessary.
  • Avoid installing new rockers with a worn camshaft to extend service life.
  • Comprehensive kit for valve train maintenance in BMW engines.

Excessive driveline vibration is caused by one of a few things, but more than likely, it is the mounts in your vehicle. They keep your engine and transmission secure for more positive shifting and driveline triangulation as well as absorbing vibration. If any of these are occuring in your BMW, it's time to examine your mounts.

The best solution for 24v Swapped E30's using an M50, M52, S50, S52US, S54, or Euro S50 Engine with the E34 525i M50 oil pan! The Achilles Motorsports Oil Pan Baffle was designed and manufactured to be used on racing, high-performance track, and street driven cars. Each baffle is precision laser cut from .090" heat-treated aluminum then hand-assembled and test fit to ensure accuracy and ease of installation. Achilles Motorsports' baffle design incorporates dual trap doors and a unique oil deflector that prevents oil from splashing out of the sump under hard braking. Together, these help minimize the sloshing of the oil inside the oil pan and keep oil accumulated around your pickup tube. The factory BMW oil pan doesn't do a very good job of keeping oil accumulated around the oil pick-up tube in high g-force situations. By keeping oil accumulated around the pickup tube you can eliminate the costly loss of oil pressure and potential damage to other vital engine parts commonly caused by high g-forces from hard acceleration and braking and high-speed cornering. Professional welding is required for installation!

This is the voltage regulator found on the back of the alternator. It's a normal wear item and the contacts are the first thing to check if you believe the alternator is not charging the battery (lights flickering or dim, battery light on in the dash, the engine quits without warning, or other electrical failures). The voltage regulator manages the voltage flowing through the car, especially to and from the battery. There are two carbon contacts on the regulator that control the magnetic field when the alternator is spinning and these contacts wear over time. A new set of contacts will be about 13mm in length. Anything less than 5mm and the voltage regulator should be replaced, regardless if that is the cause of your electrical problems or not. Most older mechanics will tell you to keep a spare regulator in your toolbox.

The carbon contacts can be replaced on their own but requires desoldering the old ones from the base and then soldering the new ones on. It may be easier to just replace the unit as a whole.

This is the OEM voltage regulator, made by Bosch or Hella. It's the one with the white base and fits most Bosch alternators from 1977-1995 (Valeo and other alternators look very different and have a black cover and base). This part number replaces the previous BMW part numbers - 12311271664, 12321279548, 12311722755, 12321711399 and Bosch part numbers 1197311021 and 1197311028.

When building a car for the track, one of the most important factors to consider is weight. Stock batteries can weigh up to almost 50 pounds and are unnecessarily large, designed to power a host of systems not normally used in a track car (radios, lighting, etc.). What can you do to cut weight the weight without affecting your car's operation? This is where Braille Battery comes in with their long line of performance lightweight battery options! Designed to provide the highest cranking power possible while being up to 75% lighter, Braille Battery is one of the foremost leaders in automotive racing batteries with nothing but high quality, high output batteries in mind! The B3121 battery from Braille is their lightest do-everything battery available, offering 1380 pulse cranking amps that can crank over V8 engines with ease while still coming in at under 22 pounds, half of the weight of a standard Group 34 battery! This is thanks to their Advanced AGM racing technology that allows them to put a ton of power into a very small package. Physical Specifications: BCI Group: All sizes Weight: 21lbs / 9.5kg Length: 6.6" / 168mm Width: 5.2" / 132mm Height: 6.8" / 173mm Polarity: Right Side Positive Terminal Type: Steel terminal block with M6 bolt Performance Specifications: Voltage: 12v Recharge Voltage: 14.4V – 14.6V Maintenance charge voltage: 13.8V 5s Pulse Cranking Amps (PCA): 1380 10s PDC: 124 Amp Hour (Ah): 31 Watt Hour (Wh): 372 Life Cycle @ 10% DOD: 3100 Charging Temperature 0C to 50C Discharge Temperature range -40C to +60C Storage temperature -40C to +60C *THIS BATTERY REQUIRES A CUSTOM MOUNTING SOLUTION. The size and weight are significantly smaller than a stock battery and will not be held in place by the stock battery mount*

This anti-drain-back check valve is located in the engine block and keeps oil from draining out of the valvetrain and vanos system after shut down. Over time these can become clogged, particularly if long change intervals are followed, allowing oil to drain out of the upper internal passageways. This can contribute to the notorious start-up rattle and result in premature vanos and valvetrain wear due to poor lubrication during startup. 2 required.
