This first generation Porsche Cayenne came from the factory with a 3.2 L VR6. However the owner sent the SUV to a talented mechanic in Rayong, Thailand for an engine swap. There they replaced the VR6 with a 2.8 L 1GD-FTV turbodiesel inline-four from a Toyota Fortuner truck. Thanks to a reader we know the Cayenne also uses a Toyota six-speed automatic transmission. They modified the wiring harness to work with the Toyota ECU and Porsche ECU.
