The VW 1.9 AHU TDI to W56 Adapter Kit will mate your VW 1.9 AHU TDI donor motor to your stock Toyota 5-Speed manual G-52/54 or W56 transmission. All hardware is included, as well as the adapter plate, dust shield, custom pilot bearing (commercially available), and starter spacer. My custom ARP flywheel bolts allow you to bolt the flywheel directly to the crankshaft, You can opt for a brand new 9-1/4" flywheel. The flywheel is machined to the TDI crank pattern and is ready to be bolted on. This new flywheel comes neutral balanced. This flywheel uses a clutch from a 1994 4x4 22RE Toyota Pickup. CKT049 by Aisin is what I recommend.


This kit was designed for the AHU Volkswagen TDI. Many other VW diesels share the same bellhousing pattern, but it is not guaranteed the components on those engines will fit the same (i.e., starter, manifolds, oil filter, etc.). The ALH will require some clearancing of the adapter plate to clear the ALH oil pan.  The Toyota starter sits in the location of the factory turbo. A pair of flanges are available to allow relocation of the AHU's K03 turbo. The ALH has a one-piece exhaust manifold/turbo. At this time, thie VNT-15 turbo will not work. At only 90 crank hp, stock, the TDI is not enough to motivate a heavier Toyota. It is assumed you will be increasing the power. Running an aftermarket exhaust manifold and turbo is recommended so you can maximize the benefits of fueling upgrades. The K03 is quite restrictive, even in stock form.
