Speaking of Fords/Mustangs/F150s - saw both a 2006 Ford GT and one of the new GTs this spring/summer at the Calgary car show. Pretty amazing car with the EcoBoost(ish) V6 in the new one. The first time I drove an EcoBoost vehicle was testing one of the Flex square looking things for my father - pretty great power, and now the Raptor equipped one is putting out more power than the previous V8 motor.
A fun project would be to pick up a used 4cyl Ecoboost Mustang and tune that up, one of my loves was an 80s Mustang that was a 4cyl turbo. It put out 175 HP, the new one stock is nearly double that. There are lots around here in the $20k range with the Ecoboost performance option, and adding another $10kCDN for a Borg-Warner turbocharger, a bigger intercooler, and a Cobb Accessport used to flash the ECU, and some other easy mods will yield a car putting 500hp to the rear wheels.
