The BTR-S40-F02 turbo turbine-inlet flange is a stainless-steel T4 divided-pattern flange for many S400-style turbochargers. It supports twin-scroll manifold designs that improve exhaust energy delivery to the turbine.

Brian Tooley Racing BTR-S40-F02 Includes:

• One stainless-steel T4 divided turbo turbine-inlet flange for S400 applications

Brian Tooley Racing BTR-S40-F02 Features:

• T4 divided inlet pattern for twin-scroll S400 turbine housings
• Stainless-steel construction maintains strength at high temperature
• Flat weld surface for accurate alignment to paired exhaust runners
• Ideal for performance manifolds seeking improved turbine response

Brian Tooley Racing BTR-S40-F02 Notes:

• Match manifold runner layout to the divided inlet for best results
• Check turbo and chassis clearance before fully welding the flange
