Hi Torque Starter, for Type 2 091 Bus Transmissions WOSP

OVERVIEW

When you''re running a high-performance air-cooled VW, the last thing you want is that dreaded slow crank when the engine is heat-soaked. The WOSP Hi-Torque Starter is the definitive solution for Type 2 owners and off-roaders who demand relentless starting power and modern reliability. Specifically engineered for the iconic 091 "6-rib" transmission, this unit utilizes advanced gear-reduction technology to deliver a massive 30% more cranking torque than a traditional Bosch-style stock starter. Whether you are powering a high-compression 2000cc Type 4 engine or a built-out performance powerhouse, this starter provides the punch necessary to fire up instantly, even in the most demanding climates and conditions.

Built to survive the rigors of both daily commuting and extreme off-road racing, the WOSP unit is a masterpiece of electrical engineering. It features a completely sealed housing protected by high-quality O-rings to keep out destructive dust, mud, and moisture. Unlike the bulky, heavy starters of the past, this sleek, lightweight design sheds significant weight from your transaxle area while drastically increasing efficiency. The 1.0 kW motor is paired with a precision-cut 4.44:1 internal gear ratio, which means it draws less current from your battery while producing significantly more mechanical output. If you are tired of the "click-click-no-start" blues or the physical weight of an old-fashioned core, this WOSP Hi-Torque starter is the ultimate professional-grade upgrade for your Late Bay Window Bus or 091-equipped sand rail.

PRO TIPS

PRO TIP 1: Eliminate the Bushing Hassle

One of the greatest advantages of the WOSP Hi-Torque starter is that it is a "self-supported" design. Unlike the original stock VW starters that rely on a small brass bushing pressed into the transmission bellhousing to support the starter shaft, the WOSP unit has its own internal support bearings. This means you no longer have to worry about a worn-out, oval-shaped bellhousing bushing causing the starter to bind or grind. When installing this unit, you can simply leave the old bushing in place or remove it entirely; the starter will align perfectly and spin freely regardless of the condition of your transaxle casing.

PRO TIP 2: Optimize Your Electrical Path

A high-torque starter is only as good as the juice it receives. To get the most out of your 1.0 kW motor, we highly recommend inspecting your main battery cables and ground straps. Over decades, the copper inside these cables can oxidize, creating high resistance that limits current flow. For the best performance, ensure you are using at least 4-gauge battery cables and that the ground strap between the transmission and the chassis is clean and tight. A dab of dielectric grease on the terminal connections will prevent future corrosion and ensure you get that "instant-fire" start every single time you turn the key.

PRO TIP 3: Checking Flywheel Engagement

Before final torquing of the mounting bolts, always ensure your flywheel teeth are in good condition. While the WOSP starter is designed to be a direct bolt-on for the 091 transmission, it is a "stronger" unit than stock, meaning it will put more force on the flywheel ring gear. If your ring gear has chipped or flattened teeth from a previously failing starter, the high-torque unit might "clash" during engagement. Always take a moment to rotate the engine by hand and inspect the ring gear through the starter hole to ensure a long and healthy life for both your new starter and your flywheel.
