Forced Induction

Forced Induction

Forced induction is the fastest way to add real power to an engine without adding displacement, and this collection covers the full range of turbocharger, supercharger, intercooler, and boost control hardware needed to build a reliable boosted platform. Whether you are running a factory turbo upgrade, swapping to a bigger frame turbocharger, adding a centrifugal or roots style supercharger, or dialing in a nitrous system for a quick shot of extra power, you will find the components here to build and support the setup correctly. Every part in this collection is organized by system type so you can move from a stock turbocharger to a properly supported forced induction build in one place. Intercoolers, wastegates, blow off valves, boost controllers, and water meth injection components are all included alongside the core turbo and supercharger hardware so the entire boost system can be sourced together.
