CNC machined from high quality aluminum and hard-coat anodized for protection and good looks, these plates will speed up setup time and ensure your cams are properly positioned before you start timing the engine.
With four cams and 24 valves to coordinate, these plates are sure to add that bit of confidence before you turn the engine over for the first time.

Cam sprocket tool for Porsche 996 / 997 GT3



STOMSKI RACING's version of this tool works on both the intake and the exhaust cams on the Cup engines and on all non-vario cams for the other GT3-type engines. 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.

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.

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.
