Will keep you guys updated. So far indy says it's serious (no shit).

I'm trying to source a new motor - damn the X5 4.8 is f-ing expensive(~5K).
The 650/750 motors are in the 2-3K range.

My concern is that if I use a 650/750 motor I'd be reusing parts (oil pan/pump etc) that may not be salvageable from my X5.
