Updated for 2020, the AMS Performance Alpha 18x kit comes STANDARD with G35-1050 Garrett© G-Series turbos, 3.5″ Downpipes, 4″ Carbon Fiber Intakes, and 4″ Turbo inlets which is capable of producing over 1650 WHP. The competition can’t compete with Alpha on engineering or on the track. All of the things that are standard on the AMS 18x kit costs you thousands extra with the competition. Prepare yourself for an over 1650 WHP capable street car that spools faster using the newest Garrett© G-Series turbos. The Alpha turbo system upgrades for the R35 Nissan GTR have been engineered from the ground up to create a line of turbo kits that would redefine GTR aftermarket performance.

Alpha R35 GTR “X Series” Turbo Systems
Every part of the new Alpha 18x kit is now improved. From the exhaust manifolds, to the intakes, to the G-series 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 of turbo systems. The SnailWorks© AMS Engineering Team has spent hundreds of R&D hours refining the Alpha “X Series” turbo systems to be the best performing, highest quality, and easiest to install kit on the market.
Totally Redesigned Tubular Exhaust Manifold
The new 18x 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 manifolds have been through an extrude honing process, resulting in a smooth finish in the entirety of the manifold interior.
The Garrett© G-Series Turbos and 3 inch Intercooler Piping
The new Garrett© G-Series turbos are a complete clean sheet redesign of the performance turbocharger lineup from Garrett©, with the intention of improving horsepower output while simultaneously decreasing spool time. Utilizing these cutting edge turbos on our turbo kits, matched with the benefits of our 4″ intakes, larger downpipes, and redesigned manifolds have shown staggering increases in horsepower compared to older technology from just a few years ago. The new G35-1050 Alpha 18x kit is over 1650 whp capable! All this is accomplished without sacrificing anything in terms of spool up time or power delivery. The future is now! The new G-Series turbochargers feature new compressor wheel aerodynamics and new turbine wheel aero constructed of Mar-M alloy rated for 1055°C. By implementing race-proven Garrett© turbos AMS have successfully delivered you more horsepower throughout the entire powerband!
To further improve power output, this Garrett© G-Series Turbo uses 4″ inlet and 2.5″ discharge compressor covers. This cover allows for greater airflow compared to a 3 inch cover found on many smaller turbo systems. The compressor discharge was maximized to allow the best possible flow given the space constraints of the GT-R. This is then fed into the high velocity cast 2.5 inch to 3 inch lower intercooler pipe. This new lower pipe offers you a drastic improvement in airflow vs its predecessor and transitions with the highest efficiency into 3″ intercooler piping.
Massive 4″ Carbon Fiber Intakes
That large 4 inch compressor inlet on the turbo needs 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. By thoroughly laser scanning the confinements of the engine bay and designing the intakes in Solidworks© CAD (computer aided design) software, AMS 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 18x turbo kit.
Tig Welded 3.5″ Stainless Steel Downpipes
As another feature of the 18x Turbo Kits, AMS have added 3.5 inch (90mm) T304 stainless steel downpipe set that will perfectly match to your existing street exhaust system. However, the Snailworks© AMS Engineering Team designed this full 3.5″ downpipe to only taper down at the exhaust flange which allows for easy custom fabrication of 3.5″ turn downs or merged as a 5″ racing exhaust, or even adapted to an off-the-shelf 102mm street exhaust. The included TiAL 38mm external wastegates dump exhaust gasses through 1.5″ atmospheric dump tubes.
NO CUTTING of the Frame Rails, Compatible with A/C and Power Steering
AMS developed the new Alpha 18x Turbo Kit 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 other 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 buy the AMS Performance Alpha 18x Turbo Kit.
