VW 1.9 2.0L TDI to Toyota 3.0L V6 (3VZ-E) Transmission Adapter Kit

Adapter Plate Kit – Toyota 3.0L (3VZ-E) to VW/Audi 4-Cylinder
This adapter plate kit allows you to replace your Toyota 3.0L (3VZ-E) engine with any 4-cylinder Volkswagen or Audi engine.

VW TDI engines like the ALH, BEW, BHW, and CJAA are the most popular swaps. All VW/Audi 4-cylinder engines share the same bellhousing bolt pattern and crank hub, meaning you can install any VW/Audi 4-cylinder gas or diesel engine using this kit.

***NOW AVAILABLE WITH OEM STYLE STARTER MOTORS. All our new kits have been modified to fit a Toyota 4.7 V8 starter motor. This is a Denso style starter motor, high torque, 2 kW power rating, affordable and readily available!***

***If you are using a R150/R151 transmission, the 3.0L and 3.4L transmissions have different length input shafts. Therefore, you can only use a 3.4L bellhousing on a R150/R151 series trans box from a 3.4L. The same goes for the 3.0L, you can only use a 3.0L bellhousing on a R150/R151 series trans box from a 3.0L. You can not mix and match bellhousings. This is not an issue for most people, just something to be aware of if you buy your bellhousing and trans box separately.***

Product Features

Our kit includes standout features that set it apart from the competition in quality and performance.

Premium Billet Aluminum Adapter Plates
We use only high-quality 6061 billet aluminum—never cast or non-tempered materials found in lower-cost kits. Each plate is heat-treated and artificially aged through a tempering process to maximize strength, durability, and toughness.

This ensures the adapter can handle real-world stress without compromise, making it a reliable foundation for your engine swap.

Extra Firewall Clearance
Our 2-inch thick adapter moves the TDI engine forward by 2 inches from the transmission bellhousing. This added space provides crucial clearance for the TDI vacuum pump and coolant pipe, helping avoid firewall interference.

The transmission stays in its original location, keeping the shifter in the factory position for most conversions—making for a cleaner, easier installation.

High-Performance Crank Adapter
Our crank adapters are built from nitride case-hardened alloy steel and rated for 800 ft-lbs of torque—engineered specifically for high-performance applications. Nitriding is a low-temperature, low-distortion heat-treating process that greatly enhances fatigue strength, making it ideal for components subjected to constant stress cycles.

Crank adapters are a critical failure point in many builds, and this is not an area where you want to cut corners. That’s why we refuse to use aluminum or untreated steel like some competitors do. Sure, those might “get the wheels turning,” but are they engineered to perform and last? Not even close.

Starter Motor Options
Our kits now include multiple starter motor options to suit different needs and preferences. The Toyota 4.7L V8 Denso-style starter motor is now our go-to for all TDI kits. It features a compact design and proven OEM reliability and is widely available at an affordable replacement cost.

For those who prefer an aftermarket option, we also offer the 2.0kW PowerMaster Chevy V8 starter. Both starter motors can be clocked in two or more positions to help avoid fitment issues in tight engine bays.

Multiple Engine Clocking Positions
Our two-plate adapter system allows you to clock the engine at 0° (vertical), 10°, or 15°, giving you the flexibility to fine-tune engine positioning for clearance. The transmission remains in its stock position while the engine is rotated slightly toward the passenger-side frame rail—great for optimizing fit without modifying drivetrain alignment.
