UN1 vs Audi 01E or 01X vs Boxster/Cayman gearbox

I went off the beaten path and put in a Mendeola. I am always up for a challenge so lets see how this thing last over time. They put them in dirt racers with big hp and torque and they get beat on so should be good in the 40. They run slightly long and rear lower needs to be trimmed or removed. We removed and installed a nurf bar.
Hi Nick,
Could You share some more info about Your Mendeola challenge? I am planning the same path. S5R Mendeola. How is fitment, shifter you used, axles? etc.
I want to use with an LS3 engine about 600HP
