The fuel pump and injector upgrade is'nt really necessary if you're satisfied with being in the 500's because you'll make a bit over 500rwhp safely with a stock block. Also invest in a good turbo blanket, titanium heat wrap, heat sleeves for the vacuum lines and transmission wiring harness. Install and break in the clutch before you get the kit and forget buying an oil cooler as Sasha provides a very good one with the kit.
