I know that you need a manifold, turbo, and oil piping for the charger.
What do you do for the fuel side? Is there anything special that needs to be done to the injection system? Do you need to get more fuel in there or do you just leave it alone? Do you just richen it up so it is ALWAYS pumping in more fuel? How do you do that?

One important mod you need to do, at least a 2 1/2 inch exhaust. With a turbo you increased inlet air you need to allow the exhaust to flow out the added air. I did a turbo on a 3B the exhaust was not done originally, Sheldon told me to install a larger exhaust, I did and the difference in performance, fuel economy and exhaust temp measured pre turbo was greater with the larger exhaust compared to smaller exhaust. Made the mods preform as I expected without the exhaust mod the turbo did not preform as I wanted.
I made a piston that replaced the fuel stop that moved to the boost level so my fuel increased as boost increased if you turn up the fuel after turbo install you will over fuel the motor until full boost.
