Why not the best of both worlds? I would choose a BMW with a T66 5 liter Ford, an FC Turbo II LS1 T56 Mazda, an FD LS1 T56 throw in a procharger, Nissan Hardbody Pickup with a 5 liter Ford C4 trans and 150 shot. Throw in a Datsun 260z LS1 T56 76mm turbo and an LS1 Lincoln Mark VII, and have a reliable fun time.
Soon to come is an SL600 with an LS1, as I have left out Mercedes, and have yet to piss off any of these purists. A Ferrari 328 with an LS7 would be some fun.
