Introducing the new Alpha 12X R35 GTR Turbo Kit!
Introducing the Alpha 12X 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 12X kit is now improved. From the exhaust manifolds, to the intakes, to the Gen II turbos, 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 previous generation.
Our Totally Redesigned Tubular Exhaust Manifold
The new 12X kits feature 2.0 inch external diameter runners which yield a 1.7 inch internal diameter for our 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. To improve the exhaust flow even further each of the manifold’s interior is Extrude Honed to a smooth mirror like finish.
Custom ALPHA 4 inch Compressor Covers and Garrett© Generation II Turbos
To further improve power output we 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 our 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. The X Turbo Kits now feature Garrett© Generation II Turbos.
WHP Gains Over Previous Turbochargers
Massive 4″ Carbon Fiber Intakes
3.5″ Stainless Downpipes
As another feature of our 12X Turbo Kits we have added 3.5 inch (90mm) Stainless Steel downpipe set that will perfectly match your exhaust system. Our Engineers designed an 8″ cast section that tapers from 3.5″ down to the exhaust flange which eliminates excessive back pressure.
NO CUTTING of the Frame Rails, Works With A/C, and Power Steering
We developed the new ALPHA 12X Turbo Systems to directly bolt in without hacking up your prized possession! Typically when you reach 1200+ HP levels drastic measures must be taken such as on our competitors kits where they start cutting frame rails, losing air conditioning etc. If you have to cut the frame rails on any kit below 2000+ HP levels in the stock location then its time to bring your car to AMS Performance.
