Hello,

I am trying to make a budget for mounting a turbo on my 2006 350z. I am at the fuel system part planning and there is some information I am struggling to find, and would like to see if I can find it here. First, I can't seem to find the Base Fuel Pressure to see if I need to upgrade my fuel pump. If I do need to upgrade it, is there is any fuel pump brand suggestions that you have? Also, to my understanding the 350z has a return less fuel system. I am trying to shoot for 400whp/480hp, so would I need to upgrade to a return system or would it not be necessary? Just asking because it doesn't seem like a huge power increase. Any return fuel system kit suggestions are welcomed too.

Thank you

 

Stock fuel pressure is ~52psi. With upgraded injectors and a 255 pump you should have enough fuel for 400whp on pump 93 or 91

 

if you’re gonna put a 255lph in the basket you might as well put a 300lph
