OK hear me out. Audi W12 swap

[truegearhead]

Over the past 24 hours I went off the deep end after I found out that an Audi W12 will bolt to the Audi 4.2L transmission which means that it will also bolt to a Boxster transmission. I also found out that a W12 is actually the same length (about) as a Boxster motor which allows you to avoid the LS1 problem. About an hour after these realizations I found myself negotiating the price to ship a (stay with me here) twin turbo W12 out of a Bentley silver spur (these motors are super cheap, under 5k) but unfortunately/fortunately the motor sold just after we settled on a price. My car is a track car, and the plan was to slowly build a tube frame for the back to accommodate any motor but with the compact packaging of the W12 I may not have too. Has anyone else chewed on this idea? The Silver Spur idea is not a good idea but the W12 idea I think is doable.
