1993 6.5 turbo options

93 uses a gm3 turbo with a spring loaded manual wastegate and no vaccum pumps on 93 trucks 94s havegm4 turbos that are vaccum controlled by the wastegate via a vaccum pump. They will bolt on but would need to use your 93 wastegate system or a manual spring loade turbomaster wastegat in my opinion id opt for a hx35 with a boost valve set for 10-12 psi max theyre more efficient at high rpms and highway speeds than the gm series turbos.
