The guys that brought you an a Jetta powered by a turbo 1000 cc motorcycle engine are back with a more “conventional” engine swap project. This time the team takes a 2003 Audi A4 and replaces the factory 1.8 L turbo inline-four with a 4.2 L V8 from a 2000 Audi A6. The swap required using a modified Passat W8 radiator and modified mounts. Watch as the team explains the project and then enjoy the loud sounds the engine makes.

Are you sure that originally it had V6? Because in the video at about 0:27 says he removed 1.8 liter.
I noticed that but he says V6 twice in the video and at 2:22 talks about the V6 having a returnless fuel system. So I just assumed (possible incorrectly) that the 1.8 L was the mistake. **EDIT** He is saying “B6 A4” not “V6 A4”.
**EDIT** You are correct. The engine is a 1.8 L turbo. You can see the badge in the newer videos. I thought they were saying “V6 A4” in this video but he is actually saying “B6 A4”. I apologize.
