I am honored to be able to be able to offer the baddest top mount turbo kit for the 6-Port/A91 Turbo EWG That was developed as a collaboration between Titan Motorsports and Full-Race Motorsports.
This is the kit I recently installed on my personal car and it is breathtaking. See below for the description from Titan and Full-Race
If you're looking to maximize power output from the A91 Supra platform, this turbo kit is for you. Full-Race’s 2021+ Toyota A91 Supra B58 6 Port Top Mount Turbo Manifold was designed specifically to take advantage of the 2021+ B58's high flowing 6 Port Cylinder Heads. This cylinder head vastly outperforms the 2 port head with upgraded turbos. Featuring high quality robotic-TIG welded stainless steel
- 2021+ Toyota A91 Supra with 6 Port Cylinder Head
- 2020 Toyota A90 Supra with 2021+ 6 Port Cylinder Head Swap
2021+ TOYOTA A91 SUPRA B58 6 PORT TOP MOUNT TURBO KIT FEATURES
- Precision Fabricated from thick wall stainless steel
- Robotically TIG welded construction
- CNC/Ported head flange
- Sealing surfaces machined flat ensuring a leak free seal
- 44mm Wastegate Flanges
This dyno comparison shows the Full-Race Supra Turbo Kit with an EFR 9280 Turbo using both the A90 vs A91 cylinder heads to demonstrate the power gains available. Full-Race developed the 2 port manifolds with Papadakis Racing early on, and we’ve collected a ton of data in that time, so using their Toyota Supra for the 6 port testing was ideal. The hardware changes on this dyno comparison were limited to the 6 port cylinder head and Full-Race 6 port turbo manifold. All other components remained 100% the same during testing.
This first comparison shows 2.2 bar boost – The yellow line is the A90 2 port head and the blue line is the A91 6 port head.
The 6 port head and manifold (blue line) swap gained ~200ft lbs of torque at 4500rpm and carried those gains through the entire power curve. There was zero loss of performance anywhere. To be clear – the new 6 port head is a plug and play swap for the 2 port. Even cams and valves / springs / Sensors / injectors / and fuel pump are all the same.
