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.

Engine connection piece, M2 x 1.5.

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.

Knock sensor.

A magnetic sump oil drain plug is a type of oil drain plug that contains a small magnet designed to attract and capture metallic particles that may be present in your engine's oil. While this type of drain plug is not exclusive to Porsche and can be used in various vehicles, it can provide several benefits, including:

Improved Engine Longevity: The magnet in the drain plug helps to capture tiny metal particles, such as iron, steel, or aluminum, that may circulate in the engine oil. Removing these particles can reduce wear and tear on engine components, potentially extending the engine's lifespan.

Enhanced Engine Performance: By reducing the presence of contaminants in the oil, a magnetic drain plug can help maintain the oil's lubricating properties, which is crucial for smooth engine operation. Clean oil can also contribute to improved fuel efficiency.

Early Detection of Problems: As the magnetic drain plug collects metallic debris, it can serve as an early warning system. By inspecting the drain plug during oil changes, you can get an idea of the engine's condition and detect any unusual wear or damage before it becomes a major issue.

Reduced Maintenance Costs: Regularly inspecting and cleaning a magnetic drain plug can prevent larger issues from developing over time. Addressing potential problems early can save you money on more extensive repairs down the road.

Peace of Mind: Knowing that you are taking steps to protect your engine from premature wear and tear can give you peace of mind as a vehicle owner. It's a relatively inexpensive and simple modification that can provide added assurance.

Easy Installation: Magnetic drain plugs are typically straightforward to install. They often replace the existing drain plug and require no special tools or modifications.

While magnetic drain plugs can offer these benefits, it's essential to remember that they are not a substitute for regular oil changes and proper maintenance. Regular oil changes with the appropriate oil and filter are still crucial for the health and longevity of your engine. Additionally, magnetic drain plugs may not capture all types of contaminants, so they should be seen as a supplementary measure rather than a comprehensive solution.
