Due to overwhelming demand Turbocharged fuel injection is coming. Testing will start March 2020 and production of units are scheduled for Late fall 2020 after hot and cold weather cycle testing have been completed. Electronic Spark knock reduction is planned and will use the factory carb as the throttle body which will limit the amount of boost as GM engineers intended.
No Corvair engine deserves EFI more than the turbocharged models due to carb issues. We will be able to retard the spark electronically based on Load, RPM and most importantly temp (air charge and engine)*. This will allow the turbocharged engine to run “carefree” under normal conditions. We will also have an over-boost protection that will bleed pressure from the intake when an over-boost situation occurs. It also has a soft boost protection which will cut either the fuel, spark or both when set levels of boost are exceeded. With the superior fuel delivery system, and electronic control of the spark (to include knock) the Turbo may finally be tamed for the normal driver. A fuel-only solution is planned for those with factory retard distributor using the logic coil and a locked-out Corvair distributor. It will use the standard crank trigger for RPM and logic coil for ignition. Fuel will be trimmed and controlled by a Wideband O2 sensor to ensure boost does not ever run lean.
This will require a Turbo crossover tube core and a Turbo Carb (I would not send a good one). We will offer to convert this one at our shop as this is a more complicated install.
Estimated cost will be $1999.00, but this is only an estimate.
