Looking to make more power with your Turbo III engine?
This high flow throttle body is larger than the factory/stock throttle body on your Turbo III engine.  It offers a nice improvement in airflow and best of all it's a direct bolt-in replacement!  
 
Note however, that there is only one barb on this larger throttle body so *if your car is still 100% bone stock*  you will either want to cap off one of the two vac lines going to the top of your TB or simply tee them into one another.  This new larger Holley throttle body comes with a brand new gasket as well to make installation a breeze.  Note that you will transfer your TPS and AIS motor over to this unit.
