VAG small car for those that don't know.

This bloke in Croatia replaced the 1.3L motor with a 24 valve VR6.

And then cut the floor out of the rear and plugged in another 24V VR6.

Though called a W12 in the commentary, it is "just" a twin VR6 Lupo.

Best to scan the pictures in the Vortex thread for fabrication details,
unless you have a couple hours to read it:
