[EvanZR1]

C6s in general are pretty reliable, and the ZR1s probably more so. They also take really well to "light" mods. Since they are forced induction, all you really need is a pulley change and tune to gain some nice power, beyond that ported blower snout, air intake and flex fuel (E85) will give nice gains. For <$5K you can take a stock C6 ZR1 and make 650-700wheel very easily.
