4 Throttle Body Injection

The 4 throttle body system will use the standard Corvair Throttle linkage, modified distributor and air cleaners.  4 throttle bodies that will NOT use progressive as 4 injectors evenly distributing fuel through 4 throttle bodies will give a better and smoother fuel burn.  There are various lock out procedures to spelled out on the forum, but the most improtant part is that all throttle bodies open evenly.

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

The 4 Throttle body Injection system can be used on 140HP engines or engines that have had the extra Carburetor pad added (Fitch type).   The factory linkage is used, but Carburetors will be replaced with Brown EFI 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.   Throttle bodies can be easily bored to 1.25″  for more top-end performance, but will require reprogramming after install for those wanting different performance parameters those originally designed.  Our TBI design allows the use of only one (1) injector per TBIU by using high pressure and advanced injectors which highly atomizes the fuel spray, even at low RPMs.  You must have your own 140HP linkage as it is NOT supplied in the kit.  Standard ignition is a GM DIS unit with pickup.   DIS spark plug wires are provided and crank trigger wheels are also available for those who do not wish to drill the harmonic balancer.
