This stage of the project is planned for 2021. We will be using throttle bodies designed to replace the Weber IDA 3C carburetors, available from Porsche aftermarket vendors. The two choices I'm considering are Borla Induction's 3003 series (created by TWM) and PMO's offering. For fuel and spark control, I'll be using the Simple Digital System EM-5.
Borla's site has a nice description of reasons why fuel injection can be superior to carburetors.
