Make sure to put a steel flywheel in it

I would suggest a 13mm p pump, 5x.024 dual or triple feed injectors, 0.093 lines, and cam. 8th gear will be tough to run with even the best setup. Have you looked into half gears? They help with the big difference between 7th and 8th gear. Also, stock shifting linkage can be used if factory appearance is a necessity.

Do you have turbo limits or cube limits?

You won't need half gears if you build good engine.we run two teeth over road gear with big turbo and 13mm p pump at 3000 rpm. You will need to needle differential though. Won't drive strait if you don't.

I'm wondering why you're using a 4020 to start with? If you're going to turbo it and put an inline pump on why not start with a 30 series with a quad and twice as many gears?
