Neat idea...mmmm...if I can just convince the wife
Seriously, my wife and I recently purchased a new fully loaded 2001 Taurus SEL with the 3.0 24V DOHC engine and let me tell you - this thing moves! The 4V Cobra motor responds very well to boost, so I don't see why this 4V motor would be any different. The engine is smooth as silk as is.
It could work, but would probably be a good amount of $$$. If you have the extra cash laying around then go for it!
