Crankcase head stud driver for Porsche All 911 964 993 996 / 997 GT3 & Turbo Models 1965-On

stomski

Double-nutting a head stud to install it into the engine case not only takes time, but can be stressful for the threads, and can lead to variations in stud depth (unless you are extra careful when removing the double nuts). Protect your hardware investment and speed installation by using STOMSKI RACING's Head Stud Driver.

Made from black oxide finished hardened steel, this uniquely designed tool threads onto the head stud but will not clamp on to the threads, making installation faster, gentler, and more accurate.

DigiDix™ Digital degree wheel sam timing system for Porsche all M96, M97, and DFI engines.

stomski

A revolution in cam timing, STOMSKI RACING's DigiDix™ - Digital Degree Wheel - provides the most accurate, easy to use degree wheel ever. No more awkward setups, questionable readings, convoluted pointers, or imprecise measurements. With DigiDix™, simply bolt the sensor/adapter to the flywheel-end of the crankshaft and secure the torsion arm. Setup time is less than one minute. You are now ready to measure crank rotation to one tenth (.1) of one degree accuracy and repeatability.

DigiDix™ includes a 3 foot cable for easy reading anywhere on the engine and fits all M96, M97, and DFI engines. Storage case included.

Heat exchanger tester for Porsche 996 / 997

stomski

Some M96/M97 engines are experiencing oil-to-coolant intermixing. While there are potentially several sources of intermixing, faulty engine mounted oil-to-coolant heat exchangers are a major source. Now, with STOMSKI RACING's M96 Heat Exchanger Tester, you can confirm if your exchanger is faulty and needs replacing, or whether the source of the contamination is elsewhere. This high-quality tool is CNC machined from 6061 aluminum, anodized for years of service, and comes complete with all gauges, seals and hardware.

About Specialist Tools

Specialist Tools for Accurate, Efficient & High-Quality Porsche Engine Rebuilds

Engine rebuilds require precise measurements, correct assembly procedures and the right equipment to ensure every component fits and functions exactly as intended. Specialist tools are essential when working on Porsche engines due to their unique engineering, tight tolerances and model-specific service procedures. These tools enable technicians and enthusiasts to dismantle, inspect, rebuild and calibrate engines with professional accuracy—reducing the risk of damage, misalignment or incorrect installation.

Whether performing a full engine restoration, carrying out timing work, inspecting internal components or installing performance parts, using the correct specialist tools guarantees a reliable, long-lasting and high-quality rebuild.

What Specialist Engine Rebuild Tools Do

High-quality specialist tools ensure precision and safety throughout the rebuild process. They are designed to:

  • Accurately measure critical tolerances, including bore, deck height, ring gap and valve clearances
  • Correctly install and remove components such as crankshafts, pistons, liners and bearings
  • Support timing procedures, including camshaft alignment and intermediate shaft setup
  • Prevent damage to delicate components during disassembly and assembly
  • Improve rebuild efficiency with purpose-built fixtures and holding tools
  • Ensure even torque application, promoting proper sealing and component longevity
  • Assist in diagnostic tasks such as leak-down testing or compression verification

Specialist tools are essential for achieving a professional-grade engine build with reliable and repeatable results.

Why Workshop Tools Wear or Fail

Even well-engineered tools degrade over time due to heavy use, improper handling or exposure to harsh environments. Common causes of failure include:

  • Metal fatigue from repeated loading
  • Worn or stripped threads on pullers, press tools or torque tools
  • Corrosion from moisture or chemical exposure
  • Heat damage from working near exhaust or cylinder heads
  • Loss of calibration, particularly with measuring or torque-sensitive tools
  • Damaged contact points from misuse or excessive force
  • Contamination from debris or workshop dirt

A failing tool can cause inaccurate measurements, unsafe working conditions or even costly engine damage.

Why Specialist Tools Should Be Replaced or Upgraded

Replacing worn tools or upgrading to precision-engineered alternatives provides clear benefits:

  • Improved measurement accuracy for critical engine dimensions
  • More reliable component installation, reducing the risk of misalignment
  • Safer workshop practices, preventing injury or engine damage
  • Consistent torque and calibration, essential for sealing and bearing load
  • Enhanced efficiency, saving time during complex rebuild procedures
  • Better compatibility with modern engines and performance upgrades
  • Higher quality rebuild outcomes, improving engine reliability and longevity

Using proper tools is an investment in the quality of the rebuild and the health of the engine.
