VW 1.9 2.0L TDI to Ford 2.8, 2.9, 4.0L Transmission Adapter Kit

(2) Adapter plates: billet aluminum, 3 engine clocking positions.

(1) Crank adapter: nitride case hardened alloy steel for high performance applications (800ft-lbs torque).

(1) Starter Motor: Toyota V8 high torque starter motor, Denso style compact 2.0kW with pre-installed 12 Pitch Pinion Gear

(1) Starter Motor Spacer: Machined from 6061-T6 Aluminum (Manual Transmissions Only)

Installation hardware: For bellhousing, crank adapter, and starter are included. No flywheel/flexplate bolts are included. You need to use M10 x 1.0 x 35mm flywheel bolts for Manual Transmissions and M10 x 1.0 x 33mm for Automatic Transmissions.

Optional Flywheel Bolts: You are now able to purchase this adapter kit with the proper Length ARP Flywheel Bolts. This Kit comes with a different Crank Adapter (M10 x 1.25 Threads) and 6x M10 x 1.25 x 35mm ARP 8740 Chromoly Bolts (Automatic Transmissions will also come with 2mm ARP 8740 Chromoly Washers)

Our kit is specifically designed to replace the Ford 2.8, 2.9, and 4.0L V6 "Cologne" engine. This kit makes the back of the VW TDI engine look like the engine block it is replacing. This means you can bolt any Ford 2.8, 2.9, and 4.0L V6 transmission to any VW TDI engine using this adapter kit.

Compatible Engines:  Ford Cologne engine family - 2.8L V6, 2.9L V6, 4.0L V6 (OHV and SOHC)

If you are replacing a Ford 4.0L V6 SOHC 1998+ (with 8 bolt flywheel), you will need to use a 6 bolt flywheel and clutch kit from the 4.0L V6 OHV (1990-1997). The 6 bolt vs 8 bolt is the only fitment issue that is easily solved.   

Flywheel recommendation (4.0L, 6 bolt, 1990-1997): LUK LFW156

Clutch kit recommendation (4.0L, 6 bolt, 1990-1997): LUK 07905 {#07-905} RepSet®; Heavy-Duty

Compatible Auto Transmission: 4R55E, 5R55E

Compatible Manual Transmission: 

- M50D-R1 (4.0L Bellhousing) 1990-2000

- M50D-R1HD (4.0L Bellhousing) 2001-2011 

Compatible vehicle applications:

***If your vehicle is not on this list, please cross reference and perform your own research. Other similar vehicle models may also be compatible. ***

Any 4 cylinder Volkswagen/Audi engine will work with our TDI adapter kits. All VW/Audi 4 cylinder engine bolt patterns are the same.

Check out the chart below for all compatible VW engines. 

Note: Our kits are specifically tested on TDI engines, so if you choose to use a VW gas or older TD diesel engines please do your own fitment research. 

HOW DOES THE ADAPTER WORK?

Our adapters make the back of the TDI engine physically resemble the back of the original engine it is replacing. No drilling or welding required, no custom flywheels, or shorted input shafts. Any transmission that originally bolted to your engine will work with this adapter kit.

WHY ARE THERE TWO ADAPTER PLATES?

Our two plate system allows you to clock/rotate the engine while keeping the transmission in the stock orientation. There are three different clocking positions: 0 degrees, 10 degrees, or 15 degrees.

DO I NEED A FLYWHEEL OR FLEXPLATE?

Our TDI kits utilize the original flywheel or flexplate from the original engine being replaced. You will not need the VW TDI flywheel, clutch, torque converter, or starter motor. 

HOW ACCURATE IS THE TRANSMISSION ALIGNMENT?

We use our Aerospace Grade CMM to pull all the dimensions off the original engine. It allows us to precisely reverse engineer the bolt pattern down to 0.0001". Incorrect alignment will cause premature failure of the pilot and input shaft bearings, excessive clutch plate wear, and internal gear binding.

HOW EASY IS A DIESEL CONVERSION?

-It depends on which vehicle you want to convert and how much mechanical experience you have.
-If you approach the conversion in stages you can get the vehicle driving in less than 5 days.
-Stage 1, do your research first, and lay out all your required tasks.
-Stage 2, focus on getting the engine in and driving with very minimal changes to engine and wiring harness.
-Stage 3, after you confirm the engine runs and drives, start your performance upgrades, custom wiring harness, gauges, engine rebuilds, etc.. This method reduces the number of variables you introduce to the project, and significantly increases your conversion success. Too many people make too many changes right from the start or try to make it perfect the first time round. Take it slow, minimize the number of changes all at once, and you will have a successful conversion!
-You will need regular mechanic tools, engine hoist, welding machine, basic fabrication knowledge, some electrical knowledge, and beverages.

DOES TDCONVERSIONS DO CONVERSIONS ON CUSTOMER VEHICLES?

-Not currently. We sell the conversion kits to get your engine into the vehicle and bolted to the transmission.
