so, i'm building a project car up.

if you must know.1978 280z, built from the ground up, she'll have 9inch wides in the backand i'm shooting for

400+ wheel horsepower.

WHAT do i need on my RB20 to get to that goal,

heres the catch..

Turbo has to be less than 1000

and it has to spool well

also, what injectors/tuning stuff will i need?

gonna need injectors, cams, a good sized turbo and possibly a diffrent intake manifold.gt30r will take you to 400whp easily and is a hair over 1k.

I will be running a t3/t04e .50 ar comp .53 ar hotside that my friend used on his KA-T. I have a feeling that this turbo will spool pretty damn fast, and should be good for 400-425 or so whp.

If your looking for a good turbo on a budget i suggest you look for a used t3/t4 like I did, and just get it rebuilt (I traded my old KA for it).

CAMS??? what the ??? i'm not a pro, but i think on stock heads and bottom end 400 is easily attainable with the right tuning and such?
