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’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.
Dyno A90 Supra
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.
