Black oxide finished hardened steel.

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.

Stomski Racing SR124 Engine case splitter for Porsche 911



No more hammering, chiseling, swearing, heating, prying or praying to get an 911 engine case apart. STOMSKI RACING'S SR124 ELEGANTLY and GENTLY separates the engine case halves and not only shortens the process of engine tear-down, but it also protects what doubtlessly is an expensive asset- the engine case itself. The rare #s matching early 911S sand-cast aluminum case, or the impossible to find 911 GT3 RSR case, or the early magnesium case that seems so fragile, all can NOW be protected from the threat of the block of wood and lead hammer, or the torch, or the pry-bar and chisel.
SR124 includes a CNC precision machined aluminum platform that you bolt to four head studs (ideally over #2 or #5) using the included thumbscrews. An over-sized drive-screw (stainless steel) is then threaded through the platform to mate with a high-load bearing in our specially designed rod cap that presses against the wrist pin of #2 or #5 connecting rod that is at bottom-dead-center. As you slowly use a wrench or ratchet to tighten the drive-screw, the torque of the SR124 splitter is evenly distributed through the entire crankshaft, pressing against ALL 8 main bearings. Once the slack is taken up, only GENTLE effort on the drive screw is required to split even the most belligerent of cases.
The SR124 platform is designed to work on all Mezger 911s (2.0 through 997) and includes Delrin inserts/sleeves that protect the head studs from scratches or dings.

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.

Oil pressure relief plug extractor Porsche 911 / 964 / 993 / 996 / 997



Tolerance between the pressure relief plug and its galley are very close, and the slightest bit of gunk, corrosion, or bur will cause the plug to freeze up in the oil passage. A magnet is rarely powerful enough to overcome the seized plug, and leaving it in place is never an option.
Using STOMSKI RACING's Oil Pressure Relief Plug Extractor makes the task of removing the stuck plug a breeze, and allows you to ensure clean oil passages, and a properly operating bypass system.

The collet-based tool slides easily into the open end of the seized plug and a simple turn or two of the internal socket head cap screw expands the tool, grasping the plug to ensure easy removal.

Anodized Aluminum.

Description of Tool
This is a 3D Printed tool for installing the Rear Main Seal on Porsche M96/M97 engines to the correct depth without damage to the seal. The tool is 3D printed from hard, black plastic and is very solid and durable. It is aimed at DIYers and hobbyists due to its low cost in comparison to the official Porsche tool, but would be well suited to small independent garages as the tool can be reused many times without damage.

How to use
Care must be taken when using this tool as although it is designed to make the installation of the seal as easy as possible, it is still possible to damage or incorrectly install the seal if care is not taken to install the seal properly. We accept no responsibility for incorrect usage of the tool and possible damage to the seal or engine of the vehicle. We advise you to always confirm with a digital calipers or other measuring device to make sure the seal is installed at the correct depth.
To use this tool you will also need 4 M10 X 75mm bolts and 4 washers. This is to allow for the extra thickness of the tool, and to spread the force from the bolts across the surface of the tool.
The seal must first be correctly orientated and then gently located into the opening around the crankshaft. To do this, leave the blue plastic ring in place and place the seal over the end of the crankshaft. Then push the seal on gently so that the end of the crankshaft pushes the blue ring out of the seal and the seal gets pushed onto the outside of the crankshaft.
Next place the RMS fitting tool over the seal and thread each of the 4 bolts into the crankshaft, through the holes in the tool. Make sure to orientate the tool so that the cut-out for the flywheel guide pin in the crankshaft lines up with the pin. Screw each bolt in slowly until they just about make contact with the face of the tool. From this point on the seal will start to be inserted into the engine.
Turn each bolt a quarter turn at a time, turning all 4 a quarter turn before tightening the first one again, and continuing the cycle. It is very important that the bolts are tightened small amounts, one at a time to make sure that the seal is inserted straight and not at an angle which will damage the seal.
Repeat this until the face of the crankshaft comes into contact with the inner face of the tool and it will not push the seal in any further. Remember that the tool is plastic so excessive force at the point will possibly damage the tool and push the seal in too far.
The 4 bolts can now be unscrewed and fully removed from the crankshaft. The tool can then be removed. It may be a slightly tight fit, and if it is difficult to remove by hand then there are slots in the sides of the tool to allow a screwdriver or prying tool to grip the tool and remove it. If using the slots, be careful to apply even force to both sides to ensure that the tool does not come out at an angle and get stuck or potentially move the seal.
Once the tool and bolts are removed, visually inspect the seal to make sure there is no damage. Then, use a ruler, digital callipers or depth gauge, check the depth of the seal. It should measure 13mm, from the face of the crankshaft to the face of the seal. As long as the tool was used correctly and is suitable for your engine, the seal will be installed at the right depth.
These instructions are only intended as a rough guide, you should always check a workshop manual or research online to ensure the part is being installed correctly. Using this tool requires some practical knowledge so if you are not confident in your abilities please do not attempt to install the seal yourself.
