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. The Powerhouse Racing V23A Turbo Manifold features equal length (and equal volume) runner design. This means that the distance from the exhaust port to the turbo is equal between all 6 runners. This not only produces a heavenly exhaust note that you won't find anywhere else, but also increases overall performance. The even exhaust pulse helps each runner to scavenge the next pulse and provides consistent exhaust pressure throughout the manifold, at the turbine wheel and at the wastegate. You will find this produces higher peak power, better spool, lower exhaust back pressure, and better boost control.

Powerhouse Racing is proud to offer our V45 Turbo Manifold for the 2JZ-GTE engine. It's made to support V-band inlet turbine housing equipped turbos like the Precision S-Cover, H-Cover and Sportsman cover turbos.

You'll notice the second two digits on our manifolds are different (eg: V23 vs V45). What's the difference between the manifolds? Runner size. Below is a chart to help differentiate between manifold runner sizes.

Runner size is an interesting debate. You can think of this in the same manner as Turbine Housing A/R if you are familiar with it. A smaller runner restricts flow, but increases exhaust gas speed. A larger runner increases flow, but decreases exhaust gas speed. Higher runner flow will result in slightly higher peak horsepower, but slightly slower spool. Lower runner flow will result in slightly lower peak horsepower, but slightly faster spool. 

The decision on what works best for you is up to how you plan on using your car. If you are trying to maximize horsepower for your turbo, a larger runner may benefit you. If you want better all around power, a smaller runner may benefit you.

None of our manifolds are poor at making horsepower. Our 23 and 45 turbo manifolds both are rated for the same horsepower. UP to 2000 or more if you have a turbo that can do it! The turbo you choose plays a much larger role in the horsepower you can make. The manifold is often better chosen after you decide what turbo you will use and where you want your performance to be.

Our 50 turbo manifolds are reserved for PRO MOD Drag Race Turbo's and paired with a capable turbo, can produce anywhere from 1500hp to over 3000hp!

Installation

PHR equal length manifolds can be a real pain to install, but we have focused on trying to ease the burden of doing so. We have included short studs for our 2JZ-GTE manifolds and provide a flange nut with a smaller flange to sit next to the runners. We have paid careful attention to the area around the stud to make sure it can seat properly and you can get the necessary tools to the nut.
