Fitment & Usage
This housing fits S400 turbochargers with a 96mm turbine wheel. Designed for big single-turbo builds or as the atmospheric stage in compound setups. The 1.58 A/R provides freer exhaust flow at the cost of slower spool — best for engines with large displacement or aggressive fueling.

FAQ
What size turbine wheel does this housing fit?
This housing is designed for the 96mm S400 turbine wheel.
Can I run this housing on the street?
Yes, but the 1.58 A/R will spool later than smaller housings. It’s best suited for high-fuel, high-horsepower builds.
Will this fit my stock manifold?
No. The housing uses a T6 twin-scroll inlet. You’ll need a matching T6 manifold and downpipe setup.
Is this OEM BorgWarner?
Yes — CPP Diesel only supplies genuine BorgWarner parts, no aftermarket copies.
Can I use it in a compound turbo setup?
Yes. The 14961016100 is often used as the atmospheric stage in S300/S400 or triple-turbo configurations.
