Return PolicyThis kit pulls together the major pieces you need to mock up and fabricate a complete turbo setup—from hot-side headers and turbo mounting, to boost control, to cold-side/intercooler piping and intake tubing. It’s a solid foundation for a custom build where you want to confirm fitment, route tubing cleanly, and assemble a reliable system with common sizes and connection styles.
At the core is a forward-facing LS turbo header set, a T4 66mm turbocharger (rated up to 800 hp), plus supporting hardware like a 44mm external wastegate and 50mm blow-off valve for boost control and compressor surge protection. The kit rounds it out with aluminum cold-side intercooler piping, 4" intake tubing/couplers and a cone filter, and 3" stainless V-band and mandrel-bent exhaust pieces for custom routing.
