The Turblown Cast Aluminium Upper Intake Manifold is a dyno-developed performance upgrade for modified turbo rotary engines. Designed to improve mid-range and top-end airflow without sacrificing throttle response, Turblown reports typical gains of approximately 5–10%+ on 400+ rwhp engines, particularly with larger engine ports.
It bolts directly to the OEM FD3S 13B-REW lower intake manifold or aftermarket lower manifolds using the factory FD3S flange. FC3S applications require an adapter and FD3S throttle body.
