About Stomski Racing

Stomski Racing for Porsche

Stomski Racing parts for Porsche models from Design911.

A Quick Look at Stomski Racing

Stomski Racing information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Stomski Racing is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

  • Typical reasons people choose Stomski Racing include improving shift precision, strengthening weak points, and upgrading components that see heavy use on track or fast road driving.
  • Common side effects if the wider setup is not considered can include increased noise, vibration and harshness, faster wear of consumables, or disappointing handling balance.
  • Match parts to how the car is used (road vs track), and consider alignment, mounts, and bushes as part of the overall setup.
  • Before committing to major work, use measurement, inspection, and alignment data to validate issues and confirm that upgrades are working as intended.
  • Upgrade in stages where possible, checking tyre wear, alignment figures, and drivability after each step.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Engine Rebuild Parts — Engine rebuild parts are typically changed during a planned rebuild or when symptoms point to internal wear such as loss of compression, heavy oil consumption, persistent leaks, abnormal noises, or contamination found during inspection. Many owners choose to replace chains, guides, seals, bearings, and gaskets while the engine is apart to avoid repeat strip-downs and to improve reliability after the rebuild.

  • Confirm the need for a rebuild with compression and leak-down tests, borescope inspection, and oil/filter analysis before ordering major parts.
  • Plan a sensible “while you are in there” list (chains, guides, seals, hardware) so labour is used efficiently.

Engine Bolts / Studs — Engine bolts and studs are replaced because many are torque-to-yield or fatigue over time, and re-using stretched or corroded fasteners can lead to poor clamping, leaks, or even failure. They are commonly renewed during rebuilds, head work, and exhaust removal, and upgraded studs are often used on performance builds to improve head sealing and reliability under higher loads.

  • Check whether specific fasteners are single-use and verify engine code, length, and specification before ordering replacements or upgrades.
  • Expect seized or corroded exhaust studs on older engines and plan for careful removal or machining as part of the job.

Crankcase Parts — Crankcase parts are changed when there is damage from bearing failure, cracks, stripped threads, or oil leaks from case joints, or when wear affects clearances and oil pressure. During major rebuilds, people also address crankcase components to correct known weaknesses in ventilation, baffles, and sealing, because case integrity and oiling passages are critical to long-term reliability.

Crankshaft & Parts — Crankshafts and related components are replaced or reworked when journals are scored, out of round, cracked, or when an engine has suffered oil starvation or bearing failure. Bearings, thrust washers, and associated hardware are renewed to restore correct clearances and maintain healthy oil pressure so that the rebuild is not compromised by repeated bearing problems.

Specialist Tools — Specialist tools are used where Porsche engine work needs precise locking, pulling, pressing, or measuring that generic tools cannot provide safely. Owners and workshops buy them to avoid damaging expensive components, to set timing and torque correctly, and to carry out rebuild and upgrade procedures (such as IMS or timing work) to a professional standard.

Input shaft flange nut socket for Porsche 911

STOMSKI RACING's version of the socket to remove/install the input shaft flange nut on the 901/911 (SR252) or 915/930 (SR252A) transmissions allows you to secure the input shaft using either end of the input shaft by mounting it to a factory tool (such as P256 from the first-gear end of the shaft) or a by using a clutch disk mounted in a vice.

Moreover, unlike the factory-style long-tube socket, with SR252 and SR252A there is less tendency to want to leverage away from the centerline of the input shaft. High quality impact-grade socket and hardened steel weldment with black oxide finish.

• SR252 for 901/911/914 transmissions.
• SR252A for 915/930 transmissions.

Each sold separately/individually.

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.

Heat exchanger pressure tester for Porsche 996/997 Turbo/GT2/GT3

Exhaust bolt repair kit for Boxster / 996 / 997 Carrera & Cayman Gen1 1997- 2009 (Not GT3, GT2 or TT engines)

stomski

With more and more broken exhaust bolts reported on the water-cooled engines, the headache of repairing a broken bolt is becoming epidemic. Tasks ranging from a simple exhaust system update through an engine removal, are consistently plagued by snapped, rusted, and broken exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in the car, and even after removal, the task is time consuming and if not done carefully can lead to a damaged head or faulty repair. STOMSKI RACING's answer to these problems is the SR067, a kit that easily, accurately, and flexibly allows you to drill out the broken bolts - with the engine still in the car- saving time and headaches. A CNC milled plate indexes precisely off the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR067 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR067 Thumb Screw).

Holy broken bolts Batman! Even the latest generation of DFI (9A1) heads on the water-cooled engines are reporting broken exhaust bolts. Tasks ranging from a simple exhaust system update through an engine removal, are consistently plagued by snapped, rusted, and broken exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in the car, and even after removal, the task is time consuming and if not done carefully can lead to a damaged head or faulty repair.

Product Information
Cam sprocket bolt tool for Porsche 993

stomski

STOMSKI RACING's version of the factory P9582 tool combines the basics of the factory tool and improves on it by adding an integral 19mm bushed socket that prevents slippage and rounding off of the cam bolt on the end of the 993 cam shafts. The cam bolt on the 993s requires a torque of 88 foot pounds. Tightening the bolt to this spec, or loosening it using a breaker bar and the factory long-armed cam tool requires dexterity, leverage, and serious luck that the deep socket does not slip off the head of the bolt, rounding it over, or busting knuckles in the process.

STOMSKI RACING's SR9582 securely holds an impact-quality socket in the center of a precision machined hardened steel socket, ensuring ease and accuracy in loosening the bolt, or setting the required torque. The bushing prevents the socket from being leveraged off the bolt head, keeping it squarely in place for the most accurate torque and security during installation and removal.
