VW 1.9 2.0L TDI to Willys L134/F134 (Go Devil / Hurricane) Transmission Adapter Kit

Adapter Plate Kit – Willys L134/F134 to VW/Audi 4-Cylinder
This adapter plate kit allows you to replace your Willys 2.2L L134 "Go Devil" or 2.2L F134 "Hurricane" engine (1937–1971) with any 4-cylinder Volkswagen or Audi engine.

The most popular swap is the VW TDI (ALH, BEW, BHW, CJAA), but all VW/Audi 4-cylinder engines share the same bellhousing bolt pattern and crank hub. That means you can install any 4-cylinder gas or diesel engine from VW/Audi using this kit.

PRODUCT FEATURES

Our kit has numerous features that set us apart from the competition.

Premium Billet Aluminum Adapter Plates
We don’t cut corners on quality. Our adapter plates are CNC-machined from high-quality 6061 billet aluminum—not cheap cast or non-tempered alternatives found in lower-end kits. Each billet undergoes a precision tempering process, including heat treating and artificial aging, to deliver the ideal balance of strength, toughness, and durability for demanding applications.

Extra Firewall Clearance
Our 2-inch thick adapter moves the TDI engine 2 inches forward from the transmission bellhousing, providing crucial clearance for the TDI vacuum pump and coolant pipe. The transmission stays in its original location, so in most conversions, the shifter remains in the factory position—making installation cleaner and easier.

High-Performance Crank Adapter
Our crank adapters are built from nitride case-hardened alloy steel, engineered specifically for high-performance builds. Rated to handle up to 800 ft-lbs of torque, these adapters are made to ensure your parts aren’t the weak link.

Nitriding is a low-temperature, low-distortion heat treatment that significantly boosts fatigue strength—essential for a component that sees constant stress cycles. This is one area where cutting corners can cost you big.

Unlike some competitors who use aluminum or untreated steel, we don’t take shortcuts. Sure, those might “get the wheels turning,”—but if you want something built to last and perform, this is the real deal.

2.2kW High-Torque Starter Motor
Each kit now includes a 2.2kW high-torque starter motor from the Chevy Duramax 6.6L—delivering reliable, powerful starts for your VW/Audi engine swap.

Multiple Engine Clocking Positions
Our two-plate adapter system allows you to clock the engine at 0° (vertical), 10°, or 15°, giving you flexibility to fine-tune engine positioning and clearance. The transmission remains fixed while the engine is rotated slightly toward the passenger-side frame rail for optimal fitment.
