The Powerhouse of Manifolds
Our manifolds are a key piece on some of the fastest and most beautiful cars on the planet. We hope to be a part of yours.
Stainless Cast Construction
321 Stainless Steel Investment Cast Construction renowned for superior resistance to high temperatures and corrosion and an incredibly smooth internal surface finish with consistent wall thickness. This manifold is built to last!
T4 Turbine Housing
Powerhouse Racing is proud to offer our S1 Turbo Manifold for the 2JZ-GTE engine. It's made to support T4 inlet turbine housing equipped turbos like the Precision S-Cover, H-Cover and Sportsman cover turbos.
Cost of Horsepower
This manifold is the ultimate balance of performance versus cost. With the ability to handle anything the latest T4 turbo technology can throw at it. The runner design to offer encourage ultimate responsiveness and flow. And wastegate priority to keep it all under control. It's impossible to find a manifold that rivals the quality and ability for the cost.
Maximum Performance
PHR manifolds are used by some of the fastest racers in the world. We take price in designing and producing the highest quality and best performing manifolds on the planet. We have manifolds that work well anywhere from 500hp to over 3000hp!
Installation and Fitment
We've design a manifold using our decades of experience, to give you the easiest to install and turbo positioning the plays nicely with all other components, like your oil drain line, your intercooler piping, your downpipe. There won't be any concessions being made to install this into your 2JZ powered vehicle.
Wastegate Priority and Boost Control
The S1 Manifold was designed with wastegate priority as a key design characteristic. We've provided maximum flow to the wastegates that no other manifold can match.
This manifold utilizes Dual 44/45/46mm wastegate flanges. Compatible with Precision Turbo, Turbosmart, Tial, and many other wastegate brands.
Some notes about boost control
Advertised spring pressure does not always follow real world turbo outlet pressures. Several factors will affect the wastegate opening pressure. Mostly it's pressure on the bottom of the diaphragm and pressure on the bottom of the valve. Pressure on the bottom of the diaphragm is easy, it's really just turbo compressor outlet pressure. Pressure on the bottom of the valve is more complicated.
Manifold design, turbo sizing, turbine size and Turbine housing A/R directly effect pressure on the bottom of the valve. These can all effect exhaust manifold pressure, not only at the turbo but at the gate as well. You can get different pressures in the collector of the manifold and at the bottom of the valve, but in general, they should be fairly close to the same, but even 1 or 2 psi will have an effect. With all of those factors added in, you cannot assume the advertised spring pressure will output actual advertised boost pressure.
A very well designed manifold/turbo combination may produce significantly less exhaust back pressure, which will increase the turbo compressor outlet pressure compared to advertised spring pressure.
The most important thing is not what is the advertised spring, but are you able to control the boost to what you want. As long as you are not boost creeping, the wastegates are doing their job.
