Building for Power

I'm looking at the performance aspect of my UZ engine right now. My stock UZ (actual dealership sticker) says it puts out 250 horses. I'd really like to have the fastest 2nd gen out there. There's a guy with a 7MGTE with 400/400 hp/torque in a 2nd Gen, and I'd like to aim for about 500/500. Any idea what the best way to do it would be?

I'm looking at forced induction and it seems easier to attain with a decent turbo. There will be lots of midrange torque and horsepower with this setup. The supercharger way seems to be slightly cheaper to attain, but more expensive getting a custom lower intake manifold. Belt slippage and overboost is another thing that worries me with this setup.

I'd obviously have to run a standalone ECU (probably Adaptronic or something), and some less restrictive headers.

I don't know if 500 is even possible in the N/A area, but it'd certainly be awesome.

Last of all, I'd like to keep cost down. How much power do you think can be attained on a small budget?

Went as far as to research nitrous oxide, and according to my sources, the 1UZ can safely handle a 100 dry shot of nitrous. Might be a good way to get cheap power (under 600 bucks for a kit), but I'd rather go all out and get a big turbo.

I would seriously consider twin turbo's, one each side, this will make awesome power and the turbo's won't need to be as big. I once saw a nissan patrol with a nissan inifity 4.5l V8 with twin turbo's and it was stupidly fast.
