hx35 is good... Off a cummins deisel. 200-300 dollars

There are so many setups. Just search. I dont have the energy to type it. I figured you at least had a budget.

Anything around a 35r should be all you need to reach your goal. An externally gated setup with even a log style manifold can reach 450 500... But thats pushing those shitty parts to the limits.

You will find it alot less frustrating if you get a tubular manifold and a "good" turbo with good piping and tial components. It sucks to have to tear it apart and replace cheap pieces 1 by 1 and buy the more expensive parts anyway. my .02

Engine management and fuel are another ball game.

DSM link and 1000's with a new 255, maybe 2...

reguardless, its expensive.

Search around and educate yourself with the setups people are already running and making around what you want.

good luck
