FAQ

Will this housing bolt to my S400SX4 with a 96mm turbine?

Yes—this 1.45 A/R T6 divided housing is designed for S400/S410SX platforms using the 96mm turbine wheel. Always verify your turbine wheel/hub and outlet connection before ordering.

How does 1.45 A/R change performance versus 1.32 or 1.58?

Compared to 1.32, 1.45 typically reduces shaft speed and backpressure at high flow (better top-end, slightly later spool). Compared to 1.58, 1.45 will spool sooner and may improve transient response at a small peak-flow tradeoff.

Is the outlet a 5.75" Marmon V-band?

Yes—this housing uses the common 5.75" Marmon/V-band turbine outlet used across many S400 builds.

What else do I need to complete the install?

At minimum: correct T6 divided manifold/up-pipes, 5.75" Marmon downpipe connection, oil feed/drain lines, and gaskets/hardware. Consider matching gaskets, clamps, and heat management based on your setup.
