Unleashing Maximum Performance: The PHR S23A Turbo Manifold for 2JZ Engines

Powerhouse Racing has done it again. Introducing the PHR S23A Turbo Manifold—an evolution of our highly regarded Billet Collector manifolds, now featuring an innovative cast collector that delivers the same incredible performance with optimized production. If you're seeking maximum power, unparalleled exhaust flow, and superior turbo efficiency, the S23A is the manifold for you.

Why the PHR S23A Turbo Manifold Stands Above the Rest


Equal Length Runner Design

The S23A is meticulously engineered with an equal length design, ensuring that each exhaust pulse reaches the turbo at evenly spaced intervals. This promotes superior exhaust scavenging, enhancing spool times, peak power, and overall engine efficiency.

Revolutionary Cast Collector

One of the key advancements in the S23A is the cast collector, offering the same high-flow efficiency as our Billet Collector versions but with improved manufacturing precision. This results in better exhaust gas distribution, ensuring smooth and efficient power delivery.

3D Port-Matched Flange

The cast flange of the S23A manifold is designed with a 3D port-matched profile, creating the best possible flow characteristics from the cylinder head to the turbo. No other flange on the market can match this level of precision, reducing turbulence and maximizing performance.

Twin Scroll & Dual Wastegate Configuration

The S23A is available exclusively in a twin-scroll configuration, maximizing exhaust pulse separation for quicker turbo response and improved boost control. Designed for dual wastegate integration, it ensures precise boost management and minimized boost creep.

S23A vs. Billet Collector: What’s the Difference?

The S23A is based on the exact same proven design as our Billet Collector manifolds. The only difference? The collector is cast rather than billet-machined. This allows us to maintain exceptional performance standards while offering a more streamlined production process.

Application & Fitment

The PHR S23A Turbo Manifold is designed for various 2JZ engine applications, including:

  • 2JZ-GE
  • 2JZ-GTE
  • IS300 (2JZ-GTE swap)
