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 or.82 A/R. 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 unique 3” cold air intake pipe is standard we also provide an option for pull-through or push-through MAF applications.
- Cast Stainless Steel V-band Up-pipe
Implementing CAD and Casting designs we are 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 AMS 750R is the perfect choice for street, road race and drag racing and the best all around turbo on pump gas. Utilizing the latest in billet compressor wheel technology makes this a better alternative to the popular 30R framed turbos that have an older, less efficient design. The AMS 750R can make an additional 100 horsepower with only a 150-250 rpm difference in spool time over the 30R. This is the ultimate weapon for street, track and drag duty, capable of up to 750 horsepower.

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 – 950 horsepower our turbo kits have just about every Subaru owner covered. On just our plain old GT30R kit with a top mount intercooler, fuel and exhaust upgrades we were 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 750R can do!
