2 Throttle Body Injection

The 2 Throttle body Injection system can be used on ALL Corvairs except the turbo version.   The 2 TBI kit can also be used on the 140 HP model, but will need block off plates (which we can supply) and will require the 140 ECM tune.  This kit will use either the modified Corvair distributor, DIS, TSP or Pertronix ignition system.   The factory linkage is used, but Carburetors will be replaced with Brown EFI Throttle body injection units (TBIU).  The Throttle body injection units must use the insulator to ensure proper height of the TBIs for linkage clearance and leverage angles.  Each Corvair engine type will have its own tune and we plan to constantly update the tune with the community of EFI tuners.  User modification of engine tune can be accomplished with laptop for those wanting different performance parameters those originally designed.   Throttle bodies can be easily bored to 1.25″ for those desiring higher top-end performance.  Our TBI design allows the use of only one (1) injector per TBIU by using high pressure and advanced injectors which highly atomize the fuel spray, even at low engine speeds.  If you have TBIUs from another EFI manufacturer (dual injectors). you can still use our system… just call and we will make it work.  The TBIUs are slightly taller than the original Carbs by approx 1/2″ to allow for  air cleaners clearance, etc.  The FC/Lakewood versions will have standard height TBIU and will have modifications to allow for connection of the air cleaner hold-down spring and height.

Carb Bases/Cores:   We will need your Carb bases shipped to us with your order.  You will recieve the carb bases you send or we can provide Carb bases at $35.00 each.  We will de-grease and clean, but these units are not intended for show quality   Please don’t send us junk as I have to throw it away, wastes your shipping and you will have to send another set of Carb bases.
