V6 and Bcal, I would love to learn more about after market injection systems and tune high hp cars in this way. However this project is for a customer who does not want to spend big bucks on an injection system. A dual plane intake, a 750 carb, a fuel pump, bolt it on, and go off-roading, sounds real good at this point. Virtually no tuning issues. As for longevity and fuel economy, this is not an issue. In either mode it will be lucky to get 12 Cdn mpg hwy and 3-7 off-road.

On the other hand, I have my daughters car which I don't mind building a megasquirt system for and playing with it for hours, for free of course! It is a 81 280 ZX turbo.
