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



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.

Black oxide finished hardened steel.

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



Some GT3 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 GT3 Heat Exchanger Tester set, you can confirm if your exchanger is faulty and needs replacing, or whether the source of the contamination is elsewhere. This set of CNC machined gauge blocks is machined from 6061 aluminum for years of service and comes complete with all gauges, seals, valves, and hardware.

Also works on the GT2 and 996/997 TT engines as well.

Exhaust bolt repair kit for all Porsche 996/997 GT3s, GT2s, and TTs.



Avoid the headache of trying to drill out broken exhaust bolts on the GT3 engines.

A CNC milled plate indexes precisely off of the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR068 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR068 Thumb Screw). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with the supplied M8x1.25 tap.

Kit includes: aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case. Now also includes our SR065D drill guide.

This tool replaces the factory tool P9653/1. Moreover, additional refinements of this tool ensures that while torquing either the 16mm hex or the triple-box cam sprocket bolts, your tool is securely bushed and supported in the center of the tool, and thus will not slip off or round off the bolts. Black oxide finished hardened steel.

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



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). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with an included M8x1.25 tap.

Kit includes : anodized aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case.

Now also includes our SR065D drill guide.

Exhaust bolt repair kit for Porsche DFI Engines on 911/997/991/ Boxster & Cayman (9A1) 2009-Onwards



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. STOMSKI RACING's answer to these problems is the SR069, 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.

Cam sprocket bolt tool for Porsche 993



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.
