PHR PowerHouse Racing PHR S23 Turbo Manifold for 2JZ-GTE

Smart Savings. Proven Performance.

PHR's Cast Collector 

PHR introduced cast collectors to offer a more cost-efficient path to proven 2JZ turbo performance—without compromising power, strength, or reliability.

Our cast collectors retain the same functional advantages as our billet designs: excellent strength, smooth flow into the turbine inlet, and durability built for real boost. The difference is in the manufacturing process. By moving to a cast collector, we significantly reduce production cost while maintaining the performance you expect from a PHR manifold.

The tradeoff is purely aesthetic. While our billet collector manifolds remain the flagship—precision-machined, visually refined, and undeniably premium—the cast collector delivers comparable performance for builders who prioritize results over appearance.

If ultimate finish and visual impact are the goal, our billet collector manifolds remain the benchmark. If your focus is maximizing performance per dollar, the PHR cast collector manifold delivers the same power potential with meaningful cost savings.

Same performance. Different priorities. Built the PHR way.
