 Product Description


Introducing the New Alpha X R35 GTR Turbo Kit!

The Alpha X Turbo Kit raced onto the scene at the GTR World Cup. Now the World’s best R35 GTR street turbo kit is available to the public. The Alpha X kit comes STANDARD with 3.5″ Downpipes, 4″ Aluminum Intake tubing, and 4″ Turbo inlets which allow the Alpha X Turbo Kit to produce over 1900 WHP! The competition can’t compete with Alpha on the street or on the track. All of the things that are standard on our X kit costs you thousands extra with the competition. Are you ready for an over 1900 WHP street car?

Introducing the ALPHA X Turbo Kit upgrade for the R35 Nissan GTR. Knowing what we now know about the goals and aspirations of our GTR customers we set our engineers loose on a line of turbo kits that would redefine GTR aftermarket performance.


ALPHA Performance R35 GTR “X Series” Turbo Systems

Every part of the new Alpha X kit is now improved. From the turbos, to the exhaust manifolds, to the intakes, to the downpipes, the kit was designed to spool faster, pull more air in, and get more air out making much more horsepower than the competition.



A Totally Redesigned Tubular Exhaust Manifold

The new X kit feature 2.0 inch external diameter runners. They are not just larger but designed in a way to feed the exhaust gasses as efficiently as possible to the new “X” Spec turbos. To improve the exhaust flow even further each of the manifold’s interior is Extrude Honed to a smooth mirror like finish.


ALPHA X Spec Turbos

To further improve power output and reliability we spec’d a turbo with a 68mm billet compressor wheel,  a turbine housing that features V-Band inlet and outlet, and a 4″ surge ported compressor inlet.


WHP Gains Over Previous Turbochargers

The new X kit is 1900+ whp capable! All this is accomplished without sacrificing anything in terms of spool up time or power delivery. The future is now! The new Alpha X Spec turbochargers do not just make more power but do so with no loss in spool. We have successfully delivered you more horsepower throughout the entire powerband! These turbos also are able to sustain higher boost levels.


Massive 4″ Aluminum Intakes

That large 4 inch turbo inlet needed some more air to feed it. Anyone that has worked on a GT-R knows how tight it is trying to get 4 inch piping to a 4 inch compressor cover on a GT-R. Thankfully here at AMS we have the best resources available. By thoroughly laser scanning the confinements of the engine bay and designing the intakes in Solidworks© CAD (computer aided design) software, our Engineers were able to develop aluminum intake pipes that utilize all of the space available. It has an actual 4″ cross sectional area throughout the entire pipe to deliver all the necessary air to the ALPHA X turbos.


3.5″ Stainless Downpipes

As another feature of our “X” Turbo Kits we have added 3.5 inch (90mm) Stainless Steel downpipe set that will perfectly match your exhaust system.



NO MODIFICATION of your Frame Rails, Works With A/C, and Power Steering

We developed the new ALPHA X Turbo System to directly bolt in without hacking up your prized possession! Typically when our competitors reach 1200+ HP levels they are forced to take drastic measures.  Because our competitor’s kits are so poorly engineered they have to start modifying your GTR’s frame rails, losing air conditioning etc. If your performance shop has to bash the frame rails on any kit below 2000+ HP levels in the stock location then its time to bring your car to AMS Performance. Optional AC compressor and line assemblies are available and are necessary to be compatible with the Alpha X kit.
