For the current generation of Porsche DFI Engines on 911/997/991/ Boxster & Cayman. (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. A CNC milled plate indexes precisely off the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR069 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR069 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. Also includes our SR065D drill guide.

When removing Exhaust Manifold Headers most cars these days end up with snapped & rusted exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in situe, and even after removal the task is time consuming. This Kit allows you to drill out the broken bolts accurately saving time and headaches. A CNC billet plate indexes precisely off the broken bolt holes & uses a uniquely designed thumb screw locator allowing the plate to be locked in place.

DigiDix™ - DIGITAL DEGREE WHEEL CAM TIMING SYSTEM A revolution in cam timing, STOMSKI RACING's DigiDix™ - Digital Degree Wheel - provides the most accurate, easy to use degree wheel ever. No more awkward setups, questionable readings, convoluted pointers, or imprecise measurements. With DigiDix™, simply bolt the sensor/adapter to the flywheel-end of the crankshaft and secure the torsion arm. Setup time is less than one minute. You are now ready to measure crank rotation to one tenth (.1) of one degree accuracy and repeatability. DigiDix™ includes a 3 foot cable for easy reading anywhere on the engine and fits all 911 and GT3 engines (and others by special order). Storage case included.

Simple Allen Key Lock Single Action. 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 . Protect your hardware investment and speed installation by using the 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.

Based on the factory P9511 tool, STOMSKI RACING's version of this tool incorporates a brass cap and a double-ended stainless steel sleeve to install the O-rings on the crankcase through-bolts. By using it, the brass cap to protects the delicate O-ring from getting cut on the threads of the bolt, you can then use the "thin" end of the sleeve to slide the O-ring over the brass cap onto the shank of the through-bolt. Once the o-ring is clear of the threads, remove the SR024 brass cap and flip the SR024 stainless steel sleeve over and use the blunt end to securely and gently seat the O-ring in the recess on the crank case.

Sprocket alignment on the 911 engine requires an accurate and repeatable ability to measure the offset of the sprockets and lay shaft. Simply using a straight edge and vernier calipers requires at least three hands and rarely produces precise measurements. Now, with the SR008, measuring sprocket alignment on the 911 engine has never been simpler, more accurate, or more repeatable. A precisely fabricated block of 6061 aluminum secures an oversized Starrett straight edge to enable easy and exact measurements. No more guessing or settling for "close enough." Includes custom caliper base, as well as thumb screws for mounting on all 911 engines including the 964 & 993 based cars.

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 cam shafts. The cam bolt on the SC, Turbo & 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 RACINGs 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 Porsche P9191 tool and the SR078 Tools. Uses 1/2" Drive Standard Braker Bar, Extensions and/or Torque Wrench. Note.
