TBI

Translate this page      using FreeTranslation.com

TBI as defined by Holley - "Throttle Body Injection (TBI) - In TBI systems the throttle body assembly has two major functions: regulate the airflow, and house the fuel injectors and the fuel pressure regulator. The choices of throttle bodies range from single barrel/single injector unit generally sized for less than 150 HP to four barrel/four injector unit capable of supporting fuel and air flow for 600 HP. The injectors are located in an injector pod above the throttle valves. The quantity of fuel the injector spray into the intake manifold is continuously controlled by the ECU. Most of the TBI systems use bottom fed fuel injectors." TBI is a less expensive way of setting up a VW for fuel injection.  TBI's are available for all year models (once we find any) through various sources listed in our links page. 

We have not found a Stock replacement TBI that will bolt on in place of your carburetor.  On the Mexican VW beetle in 2000 had a TBI system on a 1600cc engine
