GSX & RX-7

I just recently purchased A 94 RX, it has 69,700mi on it silver w/ black leather. Well where do I Start. I already know I'm throwing a Veilside on it and other basic Mods. I currently own a GSX that is heavily modified. I don't want to go as crazy as I did w/ the eclipse. Where do I start maintance wise? How much Boost can the stock Turbos take and there is some oil sepage in the Intercooler hoses. Rebuild or aftermarket (Single or Twin). How much can the stock fuel system take befor needing upgrading also the computer. Plugs? Wires? I swear by NGK & magnacore.
Are you 7 guys the same. If anyone can fill me in on some info ot will be greatly appriciated. Send me some mail!

Swoooooosh!!! Thanks Jeff
