Engineered to Win


Our AMS SnailWorks© Engineering Team has spent hundreds of R&D hours refining the AMS Performance A90 2020 Toyota GR Supra ALPHA 6 GTX3076 GEN II Turbo Kit to be the best performing, highest quality, and easiest to install kit on the market. The MKV turbo kit is designed with minimal bends and restrictions by our team to smoothly and efficiently feed more air through the intake and exhaust path and into the B58 engine. Then, focusing on the small details, our team designed the CNC machined adapters to allow the AN coolant and oil lines to install directly to the B58 engine for a leak-free install. We also designed and created our own CNC machined actuator rod adapter to allow us to mount the factory electronic wastegate to the new turbo.

The AMS SnailWorks© Engineering Team has designed the ALPHA 6 Turbo Kit to be a direct bolt-in install without hacking up your prized possession. The ALPHA 6 is fully compatible with A/C, power steering, and all other factory options, and is easily reversible back to stock with a few inexpensive replacement parts. The design of the new Toyota Supra ALPHA 6 Turbo Kit positions it to be the best performing, highest quality, and easiest to install kit on the market. The best part about the AMS ALPHA 6 Turbo Kit is that it is fully compatible with the high quality AMS 3″ Charge Pipe you already have installed so there is no need to buy a charge pipe twice like with the competition.

Hand Fabricated Tubular Exhaust Manifold and 3.5″ Downpipe


The new AMS Performance A90 2020 Toyota GR Supra ALPHA 6 GTX3076 GEN II Turbo Kit features 1.5″ ID 304L stainless steel schedule 10 piping hand fabricated to create the ultimate in exhaust flow. Incorporated into the manifold and turbine housing is a v-band connection for an easier install and leak-free operation. Additionally, because we have developed this kit as an internally gated system, there is no additional weight and flow disturbance you would find with an external wastegate design.

Our AMS SnailWorks© Engineering Team designed a downpipe that tapers from 3.5″ down to the factory exhaust joint which helps eliminate excessive back pressure. This tig welded 3.5″ stainless steel downpipe features a v-band connection, a 3.5″ flex section with smoothed internal liner, a GESI G-SPORT EPA compliant catalytic converter, and a factory style 80mm slip joint. This allows for a perfect bolt-in solution to your existing exhaust system, and the flex joint allows for natural engine movement to help prevent broken welds or exhaust hangers.

The Garrett© GTX-Series Turbo


The Garrett© GTX-Series turbos are a tried and true performance turbocharger lineup from Garrett©, with excellent horsepower output and great spool time. The new GTX3076R ALPHA 6 turbo kit is over 600 whp capable while still having excellent boost response and that world renowned Garrett© reliability! GTX GEN II compressor wheels were designed using proprietary Garrett Motion computer simulation technology focusing on CFD analysis to optimize the wheel design to reach maximum efficiency and mass flow for each turbocharger. Each GTX GEN II turbocharger can create more air mass flow, offering enthusiasts a wider range of power output when tuning the vehicle. The 8mm dual ceramic ball bearing cartridge provides optimal turbo response and reliability through its reduction in shaft motion.

To further improve power output, these Garrett© GTX3076 Gen II turbos use a 4″ inlet and 2″ discharge compressor cover. This cover allows for greater airflow compared to a 3 inch cover found on many smaller turbo systems. By implementing race-proven Garrett© turbos we have successfully delivered you more horsepower throughout the entire powerband! Our team has even gone the extra mile and pre-installed the oil and water lines to the CHRA as well as clocked the compressor cover to save you installation time and effort.

My buddy has been chewing on this for an hour!
Color: Green, Color: Green
This dog toy has been a great addition to our dog’s toy collection! My dog can be a pretty aggressive chewer, so I’m always looking for toys that are durable and can actually hold up to daily play. This one has been surprisingly tough and has lasted much longer than many other toys we’ve tried. The material feels strong and well made, and the design makes it easy for my dog to grip and chew. He loves carrying it around and tossing it during playtime. It’s also great for keeping him busy and helping reduce boredom, especially when he has extra energy to burn. Another thing I like is the texture of the toy. It seems to help keep my dog engaged, and it’s sturdy enough that I don’t worry about it falling apart right away like some softer toys do. It’s been used for chewing, tugging, and even some fetch around the house, and it’s still holding up really well. The only small drawback is that I wish it had a squeaker inside. My dog absolutely loves squeaky toys, and I think that would make it even more exciting and keep him interested for longer periods of time. Overall though, this is a very solid and durable dog toy that’s perfect for dogs that love to chew. If you’re looking for something tough that can help keep your dog entertained and reduce boredom, this is definitely worth try

Quality material and looks good.
Color: Green
Great chew toy for medium to large dogs. Seems to hold up to their chewing. Very heavy and could damage floors or furniture if your dog happens to throw it in the air.

Held Up Better Than Most for My Aggressive Chewer
Color: purple, Color: purple
I have to give the Fuufome Dog Chew Toy for Aggressive Chewers a solid 3 out of 5 stars. I have a very high-energy Lab mix named Boone who is an extremely aggressive chewer. Finding toys that last in our house is nearly impossible. This is actually his second toy like this - the first one is currently in my yard in three different pieces. While I don’t believe this toy was advertised as indestructible, I still hoped it would fully survive Boone’s chewing. Some parts have held up well, which is more than I can say for many other toys we’ve tried. However, he was still able to do some noticeable damage to the rubber portion after consistent use. To be fair, it did last longer than most toys we’ve purchased, which says a lot considering how tough Boone is on his things. For moderate chewers, I think this would hold up quite well. For truly aggressive chewers like mine, it’s tougher than average but still may show wear over time.
