As soon as I get my twin disc clutch in place, I will replace my stock turbo with a 63mm Cheetah-style turbo.

What would be my best bang for the buck fuel upgrade; 90hp injector (nozzles) on the stock pump or stock injectors with a 10mm pump?

I plan on having DRD tunes, and eventually, I plan on putting a 472 or 476 on top of it after I build a better long block.

Ideally, I would like to have both, but I am not ready to pull that trigger.

If you could only pick one or the other, which would it be and why?
