84-85 Grand National / T-Type Ported Throttle Body
Click to enlarge

Ported throttle body for your 84-85 Turbo Regal.

This mod helps the hot air cars even more than it does for the 86-87 intercooled cars.

The inlet diameter on these parts is more than .300" larger than the exit diameter. (65mm vs 57mm) Plus there is an even smaller lip between the two sections and two IAC tubes that protrude into the airstream to further restrict air flow.

The modifications done involves Machining about 5 mm from the rear section and removing the lip where the two diameters meet, It is then ground the IAC tubes flush and modify the shaft to improve airflow.

On the linkage side of the hot air throttle body is a casting boss with a recess in it that will be cut through during the boring procedure. In order to correct this, This, attached is a disk with JB Weld to cover the hole. The JB Weld method used to secure the disk works fine since this area of the throttle body doesn't see boost pressure.

Price includes a $95.00 core charge which will be refunded once core is received.
