Turbo Install Kits
Turbo install kits provide the oil feed and drain lines, coolant supply and return lines, mounting hardware, gaskets, and fittings needed to complete a turbocharger installation without sourcing individual components separately. Using a purpose-built install kit ensures correct oil supply restriction, proper drain slope, and leak-free connections at every turbocharger port. What Is Included in a Turbo Install Kit A complete turbo install kit typically includes a stainless steel braided oil feed line with an inline restrictor fitting sized for the turbocharger's journal or ball bearing type, a larger-diameter oil drain line with a heat-resistant silicone section, coolant supply and return lines for water-cooled turbochargers, a set of V-band or flange gaskets for the turbine inlet and outlet, and any required O-rings or copper crush washers for the turbocharger oil ports. Some kits include a pre-lubrication tool for filling the center housing before first startup. Why is the oil feed...
