It's a 1990 BMY with the 8.3 turbo Cummins. I know the first mods are the top low fuel screws on the MW pump and the governor adjustments. I have a 3/4k governor spring kit coming, an hx55 turbo (and rebuild kit). Can someone please shoot me a quick link for the intercooler install, aftercooler delete, and turbo install. I searched and could seem to find them. Maybe using the wrong key words. Also, how hard is it to install the governor springs? I see a lot of stuff about adjusting them, but not much about replacing them. Will order the cummins timing tapes as well to adjust final timing to 16 degrees.
