The Dual TBI – 140 Engine Kit is the Dual TBI kit with block-off plates.
Performance, Economy, and Durability:
The 2 Throttle body Injection system can be used on ALL Corvairs except the turbo version. The Carburetors are replaced with Brown EFI Throttle body injection units (TBIU). All TBIs are printed Carbon Fiber (Black) unless you special order cast Aluminum. These TBIUs are Corvair Carbs that have been cleaned, new throttle shafts installed, and bored to 1-3/16″ for higher airflow. These kits use your existing Corvair throttle linkage and distributor that is easily modified for a trouble-free, adjustable computer-controlled ignition system. 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 a laptop for those wanting different performance parameters than those originally designed. We use one (1) high-pressure injector per TBIU which highly atomizes the fuel spray, even at low engine speeds. The electronic idle control system (ICS) advances the idle when the engine is cold, or as needed on engines equipped with an Automatic transmission. We program the ECMs for the middle-of-the-road engine setups, so some engine combinations will require user adjustment with a laptop. The ECM Supports the use of single or dual Wideband O2 sensors (purchased separately) for advanced tuning and precise fuel control. The throttle body Tops are made from a strong and lightweight Printed Carbon Fiber and are our newest addition to the Brown EFI line-up. You can still request Cast Aluminum, but could delay your order.
Ignition: The standard kit has the Crank Wheel trigger system and a VAG High-Energy Ignition Coil. This configuration is simple and provides more than enough spark for Corvair engines even with extreme setups. Using this type of setup, you can create custom ignition curves and factor in things like temp. We also offer an optional GM LS ignition module that uses your standard coil. If you opt for the LS ignition, we recommend the “Flame Thrower 40011 40k” coil.
Fuel System: The engine bay fuel lines are included with the kit and provided from the rear of the engine (firewall). The Dual TBI kit includes a Fuel pressure regulator, fuel lines with fittings to both injectors, a 100 psi fuel gauge with adapter, and a fuel pulse dampener installed between the engine and body fuel line. The fuel pulse damper along with the fuel gauge will eliminate pulse pulses inside the lines that cause uneven fueling.
O2 Sensor: A Spartan3 Wideband O2 Controller and Bosch Sensor is included in the kit with weldable O2 bung. The Wiring harness is prewired for a simple connection to the WBO2 controller.
The kit includes all items from the fuel pressure regulator to the engine. The fuel pump is NOT included in the kit but is available at an additional cost.
