AMS Subaru Rotated Mount V-band Turbo Kit

The AMS Subaru Rotated Mount V-band Turbo Kit is the new benchmark in Subaru performance. Designed to meet the demanding needs of road race, drag race and street cars alike, we have successfully achieved unparalleled drivability, response, and horsepower. Our unique design has been tested and refined for over 1 year to provide reliability, OEM like fitment and options never available in a Subaru turbo kit before.

The AMS kit brings some new ideas to the table…

V-band housings:
Each AMS Subaru Turbo Kit incorporates the latest V-band exhaust housings with options for .63, .82 or 1.06 a/r. The Tial V-band housings not only provide the most horsepower and save weight but they eliminate the need for gaskets and are easier to install. No more annoying exhaust leaks and no gaskets to replace!

Top Mount & Front Mount Applications:
Another innovative feature of our kit is the option of a 4ply silicone turbo outlet pipe for either a front mount or top mount intercooler. These custom molded pieces fit better than the OEM pieces and are included at no additional charge!

Intake Pipe Solutions:
While a unique 3” cold air intake pipe is standard we also provide an option for pull-through or push-through MAF applications.

Factory ECU & MAF Solution:
We provide the option of an industry first 4 ply silcone BOV recirculation tube for cars maintaining the factory ECU and MAF.

Each AMS Subaru Rotated Mount V-band Turbo Kit is hand built here at AMS with a meticulous attention to detail. We know what it’s like to install a turbo kit so we provide all the necessary hardware and detailed instructions for a hassle-free installation.

With power output ranging from 350 – 650 horsepower we have just about every Subaru owner covered. On just our GT30R kit with a top mount intercooler, fuel and exhaust upgrades we were able to put down 485WHP and over 500 ft/lbs of torque! This same simple combination netted an 11.3 quarter mile time in a full weight 2007 STI on stock tires!!! Imagine what a GT35R can do!

Thanks again to everyone for being so patient with us on this kit. As you can see a great deal of time and thought was put into this kit.

We have about 5 cars currently running our GT30R kit with GREAT results. As was posted up top I managed to go 11.30 making 485whp through a top mount with this 30R kit. Once we get some GT35R numbers I will post them up and as always please feel free to ask any questions.
