Hi Torque Starter, for Type 1 & 002 Bus Transmission WOSP

OVERVIEW

When you are building a high-performance air-cooled engine, the last thing you want is a weak, sluggish start that fails to turn over a high-compression beast. The EMPI Hi-Torque WOSP Starter is the ultimate solution for Volkswagen enthusiasts who demand reliability and raw cranking power. Engineered to provide 30% more starting torque than a standard stock unit, this starter is a "gear reduction" powerhouse. Unlike the traditional direct-drive starters of the past, this unit utilizes internal gearing to multiply torque, allowing it to spin even the most stubborn, high-displacement engines with ease. Whether you are running a built 2275cc street engine or a rugged off-road rail, this starter ensures that your ignition cycle begins with authority every single time you turn the key.

Durability is at the core of the WOSP design philosophy. This starter is completely sealed with high-quality O-rings to prevent moisture, dust, and grime from infiltrating the internal components, making it an ideal choice for Baja bugs, sand rails, and daily drivers alike. One of the standout features of this specific model (17-2953-0) is that it is a self-supporting unit. This means you no longer have to worry about the fragile brass starter bushing located in the transmission bellhousing. By eliminating the need for that external support, you remove a common failure point and simplify the installation process significantly. If you are tired of the "click-click-no-start" syndrome associated with aging stock components, upgrading to this 1.0 kW Hi-Torque unit is the best insurance policy you can buy for your VW''s electrical system.

FITMENT

This Hi-Torque starter is designed for 12-volt systems and is compatible with the 130-tooth flywheel. It fits a wide range of air-cooled Volkswagen applications using Type 1 or 002 Bus transmissions, including:

PRO TIPS

1. Inspect Your Grounding Straps

Even the most powerful hi-torque starter cannot perform if it doesn''t have a clear path for electricity. Before installing your new WOSP unit, thoroughly inspect the transmission ground strap located near the front of the gearbox and the battery ground cable. Many "starter issues" are actually caused by high resistance in old, corroded braided cables. We highly recommend cleaning the mounting surfaces to bare metal or replacing the straps entirely with heavy-duty versions to ensure the full 1.0 kW of power reaches the motor. If your wiring is original from the 1960s or 70s, it''s time for an upgrade.

2. The Bushing Secret

Since this EMPI Hi-Torque starter is a self-supporting design, it does not rely on the small brass bushing pressed into the transmission bellhousing. While you can leave the old bushing in place if it isn''t in the way, many pros prefer to remove it entirely to prevent it from eventually vibrating loose and falling into the bellhousing area. However, the most important thing is to ensure that you are using the correct starter for your flywheel; this 17-2953-0 model is specifically designed for the 130-tooth 12V flywheel. Don''t attempt to use this on a 6V flywheel or you will damage the ring gear teeth almost immediately.

3. Check Your Solenoid Clearance

Because hi-torque starters have a different physical profile than the original "stick" style starters, always do a "dry fit" to check for clearance against the chassis or heater boxes. On some extremely tight custom builds or cars with oversized aftermarket exhaust systems, the solenoid position might be closer to heat sources than the stock unit. If space is tight, consider using a heat shield or reflective wrap on your nearby exhaust pipes to protect the starter''s solenoid from heat soak, which can lead to premature failure in high-performance or desert racing environments.
