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.

Cam nut tool for Porsche 911

stomski

This high quality tool is by far the best way to remove the nut off the end of the camshafts on early 911 engines (through 1980 1/2).

A 12-point socket fits precisely over the cam nut (46mm) while the cam holder fits through the center of the socket- ensuring no slippage, no more trashed nuts, and an easier torque of the nut.

Black oxide steel/cast.

Replaces BOTH factory tools P202 and P203.

Cam drive gear/inner sprocket puller for Porsche 911

stomski

More than occasionally the inner sprocket on the end of the 911 camshaft is jammed or fused in place and refuses to budge. The confined space of the chain box makes it impossible to leverage the gear off, and even if you can get an edge, chances are you will only cock the gear, jamming it further, or possibly breaking a tooth on the gear (or even mar the cam itself).

STOMSKI RACING's SR079 centers over the end of the camshaft and slips behind the sprocket flange, allowing you to smoothly and effortlessly slide the gear off– protecting both the camshaft and the gear itself (and the curse jar!). Black oxide hardened steel with stainless steel drive bolt.

Designed to pull the seized inner sprockets from the ends of the camshafts on and early air cooled 911 likes SC's etc, probably up to mid-993 as we think by then they stopped using the pin you slide in from outer sprocket into available slot in the inner sprocket which the tool is for, it's held in place with woodruff key to end of camshaft.

CAM BOLT TOOL for 911 3.2 CARRERA / 964

stomski

STOMSKI RACING's version of the P9191 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 3.2 cam shafts.
The cam bolt on the 3.2 Carrera 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 SR9191 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.

The SR9191 replaces both the factory P9191 tool and our SR078.
