Id rather have GSR turbo just for the fact that no matter what LS/vtec will leak oil and with turbo u dont want that. Gsr's have a good rep too, how many honda's do u know that use a GSR run 9's? they are strong motors. The LS is a strong motor too, probably can run 10psi on stock internals and maybe some Dsm injectors or other bigger injectors. My friend ran 12.7 in his Si hatch with a stock Ls turbo on 7psi.
