2021+ Toyota A91 Supra B58 6 Port Top Mount Dual EWG Turbo Manifold
Full-Race’s 2021+ Toyota A91 Supra B58 6 Port Top Mount Dual EWG Turbo Manifold was designed specifically for the high flowing BMW/Toyota A91 Supra 6 Port Cylinder Heads. This high quality robotic-TIG welded stainless steel turbo manifold is a direct bolt-on replacement for the restrictive OEM cast turbo manifold, it is designed to work with any twin scroll T4 Flanged EWG Turbocharger. We recommend the EFR 8474, 9174, and 9280 turbochargers for most setups. Garrett, Precision, and Xona Rotor Turbos will work too. If you are looking to maximize power output from the A91 Supra platform, this turbo manifold is for you.

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.
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.
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.
