Alpha R35 GTR “X Series” Turbo Systems


Every part of the new Alpha 20x kit is now improved. From the exhaust manifolds, to the intakes, to the 20x spec 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.Our SnailWorks© 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.

Our Totally Redesigned Tubular Exhaust Manifold


The new 20x 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.

New Alpha 20x Turbochargers


New for 2020, 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.The new 20x kit is 2000+ 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 20x 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, to further improve power output and reliability.

Massive 4″ Aluminum 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. 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 to utilize all of the space available. It has a full 4″ cross sectional area throughout the entire pipe to deliver all the necessary air to the Alpha 20x turbos.

Tig Welded 3.5″ Stainless Steel Downpipes


As another feature of our 22x Turbo Kits we have added 3.5 inch (90mm) T304 stainless steel downpipe set that will perfectly match to your existing street exhaust system. However, our 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


We developed the new Alpha 20x 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 our competitors kits where they start cutting frame rails, losing air conditioning etc. If you have to cut the frame rails on any street driven build with turbos in the stock location then its time to bring your car to AMS Performance. Optional modified A/C compressor and line assemblies are available directly from AMS, and are necessary to be compatible with the Alpha 20x kit.
