i LOVE the VQ motors. they make great power and are a little lighter than the VG because they are all aluminum. but, like has been said before, unless you plan on fabbing up turbo manifolds yourself (which would be pretty dope), a turbo VQ build is gonna be pricey. they are high comp motors, so you will also be looking at some lower comp pistons. to make good reliable power, it's gonna be a bit pricey.
although the VQ as an NA motor makes some nice power....
