The AMS Alpha 9 package for your Nissan GT-R offers the most reliable bolt-on horsepower available and we have the 9 second time slips to back it up. This package offers stock-like turbo spool up and driveability while boosting power output to an astounding 900 horsepower on race gas and 800 horsepower on pump gas.

The Alpha 9 Drives Like A Stock GT-R� Until You Open Up The Throttle

The best attribute of the AMS Alpha 9 package is unmatched driveability with mind-boggling speed.  Through rigorous research, development and testing, we have achieved a package with perfect driveability yet is quicker than any supercar you can buy.

Quicker Acceleration Than The Bugatti Veyron

When you lean into the throttle of the Alpha 9, a smooth burst of speed plants you firmly in your seat and pulls strong throughout the entire rev-range.  No added turbo lag and no drama, just pure exhilaration unlike anything you have felt before. So quick it, out-accelerates the $1.5 million, 1000hp Bugatti Veyron all the way to 160 mph!

A Race-Proven Package For The Street

At the heart of the Alpha 9 package are the custom AMS billet wheel ball bearing turbochargers.  Once installed these turbos appear stock yet provide enormous gains in horsepower and torque throughout the entire rev-range WITHOUT added turbo lag!  It is a win/win situation that is unheard of in the industry provided by the latest in turbo technology.  These are the same race-proven turbo's found on our 9 second Alpha 9 GT-R, Forged Performance Time Attack car and Brass Monkey Racing Team World Challenge GT-R�s so you can expect the best results.

Because of the increased exhaust flow we include our 90mm (3.5�) AMS exhaust system, one of the largest available on the market.  The bigger turbos also require more fresh air so improved AMS intake pipes are utilized. In addition 76mm free-flowing AMS intercooler piping are added to accommodate the larger volume of air being produced.  To cool the additional intake charge more efficiently our engineers designed a larger intercooler with computer designed cast end tanks for optimum flow. 

Safe Power Insured Through Proper Engineering

To safely achieve our goal of 900hp our engineering team developed a non-invasive dual-pump fuel system upgrade.  Once we had the added fuel output we were able to unleash the full potential of the AMS bolt-on turbo package by adding our race gas ECU re-calibration. The end results are over 420 additional horsepower than a stock GT-R. . . placing the Alpha 9 package in a league of its own.

AMS Engineering Provides Perfect Stock Driveability That No One Else Can Offer

We are happy to report that the Alpha 9 packages perform flawlessly in all transmission settings and have ZERO drivability compromises. No limp modes or rough driveability problems that plague all other high horsepower GT-R�s.  Our perfectly re-scaled custom AMS MAF Sensors allow us to run a properly designed intake setup with no restriction to hp, and also allow us to make the car drive like stock.
