I just bought an 85 sr5 with a 22r on the premise that I needed to replace the head gasket. Sparing a lot of painful and expensive details, I am completely rebuilding the engine from the ground up. I need guidance as to what to do with my fuel delivery. Having just an engine block (replacing the main bearings, rod bearings, new head, new rings, water pump, oil pump bla bla bla etc.) I am faced with the choice of returning to a carb (reman or aftermarket??) or converting to an RE ( factory equipment or aftermarket??). Any sage wisdom from ol' toyota freaks with much more experience than myself would be very helpful.
