Mate seriously the only way to learn is Pull the shit off, and get your ass into reading mode on the forums. It's how i know so much. Rip the shit out, find out the info you need, then put it all on. Really, it's common sence. But whats commen sence is to me, might not be for you. There is no need to pay some mechanic for a direct bolt on tubo, seriously. hardest thing for you will be changing the oil and water lines, seriously. Just use your head, plug and play computers are piss. When times get tuff, i bought a microtec LT8 for my RB20 cause it was cheap, downloaded a pin out diagram and wired it all up myself. And im far from a sparky. If you are really interested in cars, try do most of the work yourself or you'll just be one of those guys that know half the wrong information cause you listen to dribs and drabs of what your local mechanic said to the bloke beside him. Now go get your hands dirty and learn for yourself my friend! Look into the turbo upgrade thread for results and what people have for mods. 25 turbo, remap, bit more boost, dump/front pipe, cat.. will be great for a fair while.
