Forced Induction
Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...

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...
