ziggy dats hard to come by, and if u do its a pound and a crown, its better to buy new forged pistons one time or if ur turbong a 20v buy d 3mm hg it worked 4 me

Small ports never had TVIS only the big ports.

Toyota Variable Intake System (TVIS) which is a set of four butterflies located in the inlet system next to the head. These butterflies are shut below approximately 4500 RPM, effectively blocking airflow to one valve per cylinder, increasing the air speed and thus improving mid range torque. They are opened by the ECU via a small plastic vacuum tank and solenoid triggered diaphragm actuator located under the inlet manifold and open above this speed. The effect is similar to a second throat opening on a carburettor.
