Toyota Supra 2021+ B58 A90 6 Port Top Mount Turbo Manifold

Maximize Power With the 2021+ Toyota Supra B58 A90 6 Port Top Mount Turbo Manifold

If you're looking to maximize power output from the A91 Supra platform, this turbo manifold 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 heads with upgraded turbos. Featuring high-quality robotic-TIG welded stainless steel, this manifold is designed to work with any Twin Scroll T4 Flanged External WG Turbocharger or Twin Scroll T4 electronic-IWG EFR Turbochargers using an electronic actuator. We recommend the G30 / G35 twin-scroll or EFR 8474 and 9280 for most setups.

Technical Info

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 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.

Toyota Supra B58 A90

This first comparison shows a 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.
