FAQ
Does the kit include the manifold and downpipe?Yes — it centers the S300 SX-E on a high-flow T4 manifold and includes a high-flow HX40 downpipe for a complete, ready-to-install package.
What are the advantages of the 63/74 with 1.00 A/R?The 63mm compressor with the 74mm turbine and 1.00 A/R delivers a strong balance of drivability and top-end flow on the 6.7L while keeping EGTs in check.
Is supporting hardware required?For reliability at elevated boost, we recommend ARP head studs, upgraded intercooler piping/boots, a healthy lift pump/fuel system, and a quality exhaust to complement the kit.
Is this kit emissions compliant for road use?No. It is designated for closed-course competition vehicles only. The end user is responsible for legal compliance.
