Turbo Exhaust Manifold, 2ZZ-GE Thermal Wrap

Stainless steel exhaust manifold with T3 flange for the Toyota 2ZZ-GE engine, designed and produced by Radium Engineering. The T3 turbo flange is tapped for M10x1.5 studs (not included).

Engineering Design

The exhaust manifold was CAD designed and flow analyzed for maximum performance in a compact package. Unlike low flowing log style manifolds, we created a superior independent primary runner design that merge at the turbine inlet. Compared to a tubular design, these short large radius runners give the manifold extra strength and keep turbine exhaust heat energy at full potential. 

Turbocharger placement was carefully evaluated to make turbo kit installation simple. The turbocharger is located high enough to promote low resistance oil return back into the oil pan, exhaust downpipe easily clears the subframe, and turbocharger air inlet clears the transmission shifter cables.
