Since 2009, the standard practice for stock-style turbo upgrades on the R35 Nissan GTR has been to utilize the OEM “turbofolds” and machine the housings to accept larger aftermarket turbo CHRAs. The downside to this method is that the factory manifold is designed for compactness and packaging, as well as only optimized for OEM power and boost levels, meaning if you try to modify them, their limitations become apparent. Many of the current stock-style offerings on the market have lackluster boost control, or worse, excessive boost creep — some so bad that standard 93 octane pump gas cannot be used, requiring owners to run high octane race fuel at all times. With the introduction of the 2020 GT-R, our AMS Snailworks© Engineering Team knew there was a way to optimize our stock location turbo kit offerings to match the OEM two-piece manifold and turbine housing design with our own integrated improvements. By casting our own two-piece style manifolds and turbine housings, we are able to optimize all of the shortcomings of the OEM castings, including doing away with expensive core charges and machining lead times altogether. 

The AMS Performance ALPHA line of turbo kits have been the benchmark in GTR performance for years with countless world records, awards, and championships. The ALPHA name is the brand by which everything else is measured. Now, we are incredibly proud to announce the next evolution in our R35 GTR turbo kits, the OMEGA Turbo Kit line. Taking its name from our most notorious street car build to-date, the ALPHA OMEGA GTR, our mission with the OMEGA line has been to deliver the best performing and most reliable street car turbo kits — without compromise.
