This TD Conversions kit allows you to attach any transmission found on a Jeep 4.0L i6 (1992-2006) Wrangler TJ, YJ, XJ engine to any 4 cylinder turbo Volkswagen/Audi 1.8T or 2.0T gasoline engine (2001-2014, newer engines may also work with this adapter kit).
This kit makes the back of the Volkswagen engine look like the engine block it is replacing. This means you can bolt any Jeep 4.0L i6 (1992-2006) transmission to any 4 cylinder turbo Volkswagen/Audi 1.8T or 2.0T gasoline engine (2001-2014, newer engines may also work with this adapter kit).
The 1.8 liter turbo was available in these vehicles:
-Jetta, Golf, Beetle (2001-2006, MK4)
-Audi A4 (1999-2005 B5, B6)
-TT (1998-2006 MK1)
The 2.0 liter turbo was available in these vehicles:
-Jetta, Golf (2006-2014, Mk5 MK6)
-Audi A3, A4, TT, Tiguan (2006-2014)
All VW/Audi 4 cylinder engines have the same bellhousing bolt pattern and crank hub. This means you can install any 4 cylinder gas or diesel engine made by VW/Audi using this kit.
Our kit has numerous features that set us apart from the competition.
PREMIUM BILLET ALLUMINUM ADAPTER PLATES. We do not skimp on quality, and only use high quality 6061 Aluminum billets. Our tempered 6061 is far superior to the cheap cast non-tempered aluminum adapter plates typically seen with cheaper adapter kits. Our billets undergo a tempering process of heat treating and artificial aging to achieve the perfect strength and toughness for our application.
EXTRA FIRE WALL CLEARANCE. Our 2 inch thick adapter moves the engine forward 2 inches from the transmission bellhousing. This gives you more working space and extra fire wall clearance. The transmission for most vehicles will remain in the original position, keeping the shifter in the factory position is ideal.
HIGH PERFORMANCE CRANK ADAPTER. Our nitride case hardened alloy steel crank adapters are designed for high performance applications. Rated at 800 ft-lbs of torque, we set the bar high and make sure our parts are not the limiting factor in your build. Nitriding is a low temp, low distortion heat treating process that significantly improves fatigue strength of the metal. Crank adapters undergo significant stress cycles, making them a critical failure point. This is not where you want to cut corners on quality materials or design. Shockingly, our competitor's kits only offer aluminum or untreated steel crank adapters. Is it cheap and dirty, does it make the wheels turn at the end of the day, sure! Are they engineered to be the best? Not a chance!
2.0kW HIGH TORQUE STARTER MOTOR. Our competitor's kits typically come with a 1.4kW starter, but we have stepped up the cranking power and included a High Torque Chevy V8 starter from PowerMaster. Also, the starter has two clocking positions to allow for the perfect fit in your engine bay.
MULTIPLE ENGINE CLOCKING POSITIONS. Our 2 plate system allows the engine to be clocked at 0° (vertical), 10°, and 15° degrees for fine tuning engine clearances. The transmission stays stationary while the engine rotates towards the passenger frame rail.
(2) Adapter plates, billet aluminum, anodized finish, 3 engine clocking positions.
(1) Crank adapter; nitride case hardened alloy steel for high performance applications (800ft-lbs torque). Pilot bearing pre-installed for manual kit.
(1) Power Master high torque starter, compact 2.0kW starter motor
(1) Starter motor clocking adapter; billet aluminum, anodized black
Installation hardware for bellhousing, crank adapter, and starter are included. No flywheel/flexplate bolts are included. You need to use OEM equivalent flywheel bolts.
OEM flywheel bolt size: 6 bolts, 1/2 - 20 x 0.875"
This kit makes the back of the VW engine look like the engine block it is replacing. This means you can bolt any Jeep 4.0L i6 (1992-2006) Wrangler TJ, YJ, XJ transmission to any VW 1.8T 2.0T engine using this adapter kit.
***1987-1991 4.0L engines will need a different pilot bushing, please order the 4.0L pre-1992 adapter kit if this applies to you.***

Any 4 cylinder Volkswagen/Audi engine will work with our 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 VW 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 VW adapter kits utilize the original flywheel or flexplate from the original engine being replaced. You will not need the VW 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.
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.
DO AUTOMATIC TRANSMISSIONS WORK FOR CONVERSIONS?
-Yes an automatic transmission will work with our adapter kits.
-You will need a standalone TCM controller for your specific transmission. These controllers are highly tunable and have manual shift modes.
