mate im afraid for $600 your not gona get much for a highquality new turbo, 2nd hand however for that price id be looking for a r34gtt turbo, direct bolt on in regards to everything such as dump pipe, oil + water lines. with supporting mods should see you to around 190-200rwkw, your last post should be deleted lol, try at the top of this section of the forum the rb20 turbo upgrade thread, shows you alot of peoples set up and how much power they made. p.s dont use teh wrecker who tried to sell you a gtr turbo,, knows nothing bout anything and is trying to rip you off..
