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.

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.

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 hole can be used 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 (valve and hose sold separately, watch for our model specific drain kits!)

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

This is an OEM MAHLE fuel filter that removes dirt and other particle contaminants from your fuel.

A clogged fuel filter makes it difficult for your engine to get all the fueling it needs. Filters commonly clog from a deteriorating gas tank, bad fuel, or other debris in the fuel system. A fresh fuel filter addresses many fuel related problems including surging, stalling, cold start issues, and poor performance under a variety of conditions.

    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!

    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.

    This set of OEM gaskets covers everything you might need when re-sealing the bottom-end of the E30 M3's S14 engine. Using a complete gasket set will save you time and money if you have the engine out of the car and are performing any major repairs with the oil pan and timing covers off the motor. This is the correct S14 bottom-end gasket set, not a re-packaged M10 kit.

    This set of gaskets is a both a time and money saver. It includes all of the commonly replaced gaskets, seals, and o-rings when performing this overhaul. Having these on hand instead of chasing them down at the last minute will save you time, money, and frustration. With this area of the engine apart you're going to want or need to replace these items anyway to ensure it's free of fluid and vacuum leaks. This is especially important because some states have very strict emissions regulations and vacuum and oil leaks can lead to failed inspections tests. On newer cars this can also create issues in the on-board diagnostics system. Even if you're not pulling the head this set includes so many valuable parts you'll want to keep this on hand to use for spares.

    With more than 100 years in the industry, Elring is one of the oldest names in the European autoparts segment. Delivering OE-quality you can rest assured the job will be done right the first time.
