AMS Alpha 12X Version II Turbo Kit
Introducing New Alpha 12X Version II Turbo Kit!
In 2009 AMS set out to manufacture the best Nissan GTR twin-turbo system upgrade on the market. Over the next 3 years the ALPHA 10 and ALPHA 12 kits were born and proved to be the world leader in aftermarket performance for the R35 GTR.
From there they modified the existing Alpha 10 and Alpha 12 kits to accept even larger billet turbochargers. With this AMS introduced the ALPHA 16 Turbo System which is still considered the best big horsepower streetable turbo kit. The ALPHA line of turbo kits has set more records and won more races than any other kit on the market. Now Alpha has taken the next step.
Introducing the ALPHA 10X, 12X, and 16X turbo upgrade for the R35 Nissan GTR. Knowing what they now know about the goals and aspirations of the GTR customers they set their engineers loose on a line of turbo kits that would redefine GTR aftermarket performance.
ALPHA Performance R35 GTR “X Series” Turbo Systems
The new 10X kits are a total transformation from the widely popular Alpha Performance 10, 12 and 16 turbo kits. Quite literally every part of the kit is now improved. From the exhaust header to the intake to the downpipes, the kit was designed to pull more air in and get more air out making much more horsepower than before.
Totally Redesigned Tubular Exhaust Manifold
Gone are the internal 1.5 inch manifold runners found on the ALPHA 10 and 12 kits. The new 10X kits feature 2.0 inch external diameter runners which yield a 1.7 inch internal diameter for the new turbo kits. They are not just larger but designed in a way to feed the exhaust gasses as efficiently as possible to the new “X” branded kit turbos.
Custom ALPHA 4 inch Compressor Covers
To further improve power output they designed new custom cast 4 inch ALPHA branded compressor covers. The new cover increases the compressor inlet size from 3 inch to a full 4 inch cover. The compressor discharge is also not only larger at 2.5 inches vs 2 inches but the routing of that discharge was maximized with a super smooth radius to allow the best possible flow given the space constraints of the GT-R. This is then fed into a high velocity cast 2.5 inch to 3 inch lower intercooler pipe. This new pipe offers you a drastic improvement in airflow vs its predecessor and transitions with the highest efficiency into 3 intercooler piping.
100+ WHP Gains Over Previous Turbochargers
Preliminary testing of these new X turbos with the prototype kits WITHOUT the benefits of Alpha’s new compressor covers, 4″ intakes, or larger downpipes have shown a 100 whp increase on the 10X vs the 10. The new 10x kit is 1200-1250 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 10X, 12X, and 16X turbochargers do not just make more power but do so with no loss in spool vs the standard ALPHA 10 and 12 counterparts. By implementing proven Garrett GTX based billet ball bearing turbos they have successfully delivered you more horsepower throughout the entire powerband! These turbos also are able to sustain higher boost levels.
Massive 4″ Carbon Fiber 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 at AMS they 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, their Engineers were able to develop an organically shaped carbon fiber intake pipe to utilize all of the space available. While unconventional in its shape it has an actual 4 cross sectional area throughout the entire pipe to deliver all the necessary air to the ALPHA 10X turbo kits. The Carbon Fiber material itself needed to perform just as well.
Typical clear coated carbon fiber used in this industry would discolor (turn yellow) and deteriorate over time if used in this application. To get around this they sought out a high temperature polished alternative found in hard-core motorsports applications. This Hi-Temp, PrePreg material features 3-layers of 1mm Twill Weave which will sustain a 240C temperature threshold while maintaining structural integrity and maintaining aesthetic appearance without discoloration.
3.5″ Stainless Downpipes
As another improvement they have added 3.5 inch (90mm) Stainless Steel downpipe set that will perfectly match your exhaust system.
No Cutting Frame Rails, Works With A/C, Power Steering
Typically when you reach 1200+ HP levels drastic measures must be taken such as cutting frame rails, losing air conditioning etc. AMS developed the new ALPHA 10X Turbo Systems to directly bolt in without hacking up your prized possession!
