Forced Induction Systems, Turbos & Supercharger Parts

Forced Induction Systems, Turbos & Supercharger Parts

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 components from BorgWarner, Garrett, Turbosmart, AEM, Agency Power, and other leading forced induction brands.

Popular Upgrades

Garrett GTX and G-series ball bearing turbochargers for common import and domestic platforms provide broad compressor maps and improved spool response compared to journal bearing predecessors, making them a popular upgrade choice for builders moving beyond the factory turbocharger's flow limitation. Turbosmart external wastegates in 38mm and 50mm sizes, blow-off valves with recirculating and atmospheric vent options, and boost controllers with electronic solenoid actuation complete the boost control system around any turbocharger upgrade. Agency Power and AEM front-mount intercooler kits for popular platforms provide significant charge temperature reductions compared to factory top-mount intercoolers, unlocking additional power from timing and fueling maps that were previously knock-limited by high intake air temperatures.

Performance and Handling

A forced induction system requires supporting hardware that matches its flow capacity, as a large turbocharger with an inadequate intercooler loses most of its efficiency advantage to charge temperature rise between the compressor outlet and the throttle body. Intercooler sizing should target an outlet temperature within 20 to 30 degrees Fahrenheit above ambient air temperature at maximum boost and airflow, which requires a significantly larger heat exchanger than most factory equipment provides on production turbocharged vehicles. The entire forced induction air path including intake pipe, intercooler core, intercooler piping, and throttle body must be properly sealed, as boost leaks at any pipe joint reduce manifold pressure at the engine while allowing the turbocharger to spin faster to compensate, accelerating compressor bearing wear.

What is the difference between a turbocharger and a supercharger?

A turbocharger is driven by exhaust gas energy that would otherwise be wasted through the exhaust pipe, using a turbine wheel in the exhaust stream to spin a compressor wheel in the intake air stream without direct mechanical connection to the engine's crankshaft. A supercharger is mechanically driven directly from the crankshaft through a belt or gear drive, providing instantaneous boost response from idle without the lag period associated with turbochargers that must wait for exhaust energy to build before delivering full pressure. Roots-type and twin-screw superchargers deliver full manifold pressure from very low RPM but consume crankshaft power to drive the rotors, while centrifugal superchargers build boost progressively with engine speed similar to a turbocharger but retain the instant response advantage of belt drive without the exhaust system complexity of a turbocharger installation.

What supporting modifications does a forced induction build require?

A safe and reliable forced induction build requires upgraded fuel injectors sized for the increased fuel demand at boosted air-fuel ratios, a high-flow fuel pump that maintains fuel pressure under maximum demand, an ECU calibration that correctly maps fueling and ignition timing at boosted manifold pressures, and an intercooler sized to prevent charge temperature from negating boost efficiency gains. Engine internals including pistons, connecting rods, and head gaskets should be evaluated for the target boost pressure, as OEM castings are typically safe to 8 to 10 PSI on a well-supported build but require forged replacements beyond those levels on most production engines. An oil feed line and drain line for the turbocharger, water cooling provisions for ball bearing units, and correct grade engine oil with appropriate change intervals complete the lubrication support for a reliable turbocharger installation.

Why These Parts Fit Right

Forced induction components in this collection are cataloged by application, flange specification, compressor map, and boost level compatibility to ensure correct system matching between turbocharger, intercooler, and boost control hardware. Wastegate and blow-off valve specifications are matched to turbocharger flow rates and target boost pressures. Fast shipping from stocked inventory keeps your forced induction build moving forward.
