CTS Turbo is excited to announce the release of our latest Turbo Kit, designed specifically for the 2021+ Toyota Supra with 6 port engine. This kit builds on the success of our previous release and incorporates new technology to optimize performance and maintain factory fitment.\n
\nOur engineers utilized transient flow analysis and flow bench testing to optimize the twin scroll turbine housing for a GTX3582R-style, while maintaining stock fitment, stock location, and using the stock wastegate (this is not a hybrid turbocharger). This allows for the use of any stock fitment exhaust downpipe, intake, and charge pipe. The result is a factory-location big turbo that is capable of producing a record-shattering 879whp + with supporting mods. You can simply transfer your factory wastegate, high performance downpipe, intake and charge pipe during the install. No custom parts are needed!
\n
\nThis kit was rigorously tested by Titan Motorsports on their race cars and achieved 879whp + without the use of nitrous (stock engine block). Our optimized twin scroll design allows for building boost very close to the stock turbo.
\n
\nThe kit features a complete brand new turbocharger, with no need for a core to be sent in or purchased. It includes a GTX3582R-style Gen2 ceramic ball-bearing CHRA (dual ball-bearing), billet 11 blade compressor wheel, proprietary stainless steel turbine housing, flow matched to the turbocharger, VSR balanced to exceed OE tolerances, 4-inch turbo inlet, oil and water fittings, and is compatible with factory installation hardware (not included) and factory wastegate actuator (not included, use your original wastegate actuator).
\n
\nUpgrade your Supra today with the latest in turbo technology from CTS Turbo and experience the true power of performance.

98% cotton comfort
Color: Black, Size: Large
It's true to size. I have a 42" chest and typically wear a large. I ordered large and it fits. Grab these while you can as most of these mock neck t shirts are a cotton poly blend. These are 98% cotton. This is important because although the cotton/poly blends dry quicker, they are uncomfortably warm if it gets above 70 F. I have purchased other mock turtlenecks and had my local dry cleaners convert them from long sleeves to short, but they are slightly heavier weight than these. I do wish that they made these in a dark green or military green color.

100% SYNTHETIC CONSTRUCTION!!!
Color: All White, Size: XX-Large, Color: All White, Size: XX-Large
When I bought this shirt, the listing claimed it was 95% cotton and 5% spandex... the shirt that arrived was 51% polyester, 43% viscose and 6% spandex! I have been impressed by some of their other clothing, but this is the first time I was completely lied to and bamboozled. I probably wouldn't have noticed if the shirt wasn't so hot, shiny, and uncomfortable! I will absolutely be returning this shirt. Not even CLOSE to what I wanted. Quite, quite disappointed.
