I'm looking at this from an enthusiast standpoint, not what it's worth (because we'll never get our money out of them anyway). I'd like to keep the original 'flavor' of the SC's V6, yet get better mileage, smog control, and power output (with a supercharger). I'd also like to mate a 6spd manual to it. To wring 500 hp out of a more modern, lighter weight powerplant would be the goal. I plan on keeping the car for a long time, so a unique drivetrain project will keep me busy for a while.

Unfortunately, that is a FWD engine platform though. Would be a neat project if it were possible. Problem is that a new engine like the TT 3.5 would cost 4-5 times what the car is worth. Let alone the transmission problem and the wiring and electronics to make it work.
I'm thinking a new style retro bird with v8 sc powered Jag setup would be nice for a project. But even then....An eco boost retro bird....ohhhhhhhh now that be different!
