But moments after driving it in the US the engine gave up. I spent hours dismantling the engine to find the issue which turned out to be fuel. So now i either need to repair the standard RS6 engine or look at other options whilst @tavarish is here to help me!

Notes
In these opening minutes, we are introduced to the rebuild of an Audi RS6 GT3 with a focus on the shocking discovery of a seized engine after a fuel issue. The host explains that the engine block has a hole, rendering the current unit unsalvageable and forcing them to search for a replacement powerplant. He documents sourcing a secondhand RS7 engine that is believed to be compatible, while noting that the RS6’s US market makes finding a direct engine tough. The team begins by swapping essential components, including an alternate alternator and preparing to mate the RS7 engine to the RS6 subframe. This section sets the tone for a high-stakes, multi-vehicle compatibility challenge that drives the rest of the episode.
