4 Throttle Body Injection

This setup will use the standard Corvair Throttle linkage and air cleaners.  4 throttle bodies that will not use progressive as 4 injectors evenly distributing fuel through 4 openings will give a better and smoother fuel burn .

2 and 4 TBI have been developed and currently undergoing testing and the 2 TBI version can be used on the 140 with block-off plates if needed.

Production model will differ


The 4 Throttle body Injection system can be used on 140HP engines or engines that have had the extra Carburetor pad added.   All linkage will be used and Carbs will be replaced with Throttle body injection units (TBIU).   The Throttle body injection units will fit with normal gaskets, but will need insulator to ensure proper height of the TBI.  140 HP Corvair engine has its own program which will be supplied after purchase and throttle bodies can be bored to 1.25″ if desired for more top-end performance.  Program can be modified after install for those wanting different performance parameters those originally designed.  You must have your own 140HP linkage as it is NOT supplied.  Standard ignition will be VR distributor, Vortec ignition with E-core coil.  Using standard coil will produce less spark and overheat ignition coil which will cause failure.  HEI and DIS is available if desired but will take a different wiring harness.
