AMS Perfomance Rotated Mount 900X V-Band Turbo Kit for 2002-2007 Subaru WRX/STI

The AMS 02-07 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, AMS has successfully achieved unparalleled drivability, response, and horsepower.  Their 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 housing.  The Precision Turbo 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!

  • Intake Pipe Solutions

While a 4” Non-MAF short ram intake is standard, but AMS also provides an option for a 3” cold air intake for a pull-through MAF solution.

  • Cast Stainless Steel V-band Up-pipe

Implementing CAD and Casting designs AMS is able to produce not only an extremely strong and reliable piece but one that is not limited to the restrictions of a hand fabricated up pipe. Smooth transitions, optimal pipe diameter and solid construction make the up-pipe another key component to the AMS Subaru Rotated Mount Turbo Kit.

The new AMS 900x is the same turbo that powered AMS to their 2009 Redline Time Attack Championship win. Utilizing the latest in billet compressor wheel technology and a newer, more efficient turbine the AMS 900x provides enormous power with the best possible spool up characteristics making the popular GT35R obsolete!  

The AMS 900x can make an additional 150 horsepower with only a 150-250 rpm difference in spool time over the GT35R.  This versatile turbo is great for street, track or drag cars and is capable of up to 900 horsepower making it the best choice for an all around powerhouse! 

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

With power output ranging from 350 – 950 horsepower AMS turbo kits have just about every Subaru owner covered. On just a plain old GT30R kit with a top mount intercooler, fuel and exhaust upgrades AMS was able to put down 485 whp 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!!! Just imagine what an AMS 900x can do!
