What kit is it? I think all but one turbo kit from a manufacturer requires the use of a tubular k member on new edges. In any case, you would need pretty much new everything. Hot side and cold side piping, headers...etc...etc... But the turbo itself should work and possibly the BOV and intercooler might fit. IMO grab an On3 kit, and put a better turbo on it. Or piece a Vortech kit together (you can usyally get away with buying the parts separately between 1500-2000), if you don't care how you get F.I.
