AMS Alpha 6 GTX3076 Gen II Race Turbo Kit | 2020 Toyota GR Supra

The AMS Performance A90 2020 Toyota GR Supra Alpha 6 GTX3076 Gen II Race Turbo Kit was the first publicly available internally gated full turbo kit for the A90 that keeps the OEM electronic wastegate. The factory ECU keeps controlling boost as designed, and the electronic wastegate gives better boost response than mechanical setups for part throttle and on-off throttle driving like a road course.

At its heart is a Garrett GTX3076 Gen II with a 58mm inducer, 8mm dual ceramic ball bearing cartridge, 4" inlet and 2" discharge compressor cover. AMS says the kit is capable of over 600 whp. The oil and water lines come pre-installed on the CHRA and the compressor cover comes clocked to save time.

The hand fabricated tubular manifold uses 1.5" ID 304L schedule 10 primaries with a V-band to the TiAL internal wastegate housing and 3.5" V-band discharge. The 3.5" TIG welded 304L downpipe has a flex section and a factory style 80mm slip joint. CNC billet AN adapters, a billet wastegate rod adapter, powder coated 4" intake piping with dry media filter and all hardware are included. It works with A/C, power steering and factory options and can be returned to stock.

This is the Race version that replaced the earlier 49-state catted kit, so it is not sold as an emissions legal part; check your local laws. A custom charge pipe must be fabricated unless you use the AMS GR Supra 3" charge pipe.
