Decided that the Ecotec from the VS that has been sitting in the engine bay would go and decided to go the route of the L67 Supercharged V6. Bought this donor car for a good price.
Had an unregistered permit for 10 days or so and gave it a bit of a test drive. The car goes rather well. The motor is a little oily and greasy, but will definitely need a clean up and a set of new gaskets put through it.
