Well, I have been doing alot of reading here recently as I am preparing to turbo my 2006 350z. I do however have a few questions regarding the 350z fuel setup. I already have a UTEC and have recebly acquired an inline fuel pump, and APS injectors. HERE:

My goal is 400whp with a good tune and probably a TO4E 60 trim turbo (I am still not 100% sure about the turbo, GT35882R is also an option) I will stay with 400whp max. I want to have a reliable setup, without worrying about bent rods. This is not my DD, but rather a "toy" car.

As far as fuel setup goes what are optinos with this inline pump?
Do I need to do a fuel return, if so what is involved and where does the return go to? I heard that some people route it back to the inline fuel pump infeed, is this correct? Do I need a FPR for my base pressure or is the stock setup ok?

I know it's a few questions but some help would be greatly apreciated. I am not new to FI so there is non need to go in to great detail.

Thank you

 

I ran 425 on a stock block for a very long time WITHOUT a frs

 

^ Glad to here that. I plan on running a little over 400 and was going to use stock fuel system.

 

FRS? Fuel return ?? So leave everything as is, and install the inline fuel pump? From what I have read the stock fuel pump can't supply enough fuel for FI.

 

Get a walbro 255lph and put it in the fuel tank. I would not use a inline Aux fuel pump. I was talking about not using a fuel return... FRS is fuel return system.

 

You could use the inline 255 with an intank 255. This will boost the effectiveness of the inline 255, as it is being fed fuel now instead of having to draw it.

 

Redundancy maybe? If the intank pump can provide me with enough fuel, why have an inline? Just another thing that can brake.

So what I'm getting here for advise esentialy is to just buy an intank fuel pump and that's it, right?

Seems to easy, but if that's how it is then that's how I'll do it.

 

You said you already had the inline. You can never have to much fuel.

 

thawk brings up a good point but for your power goals the intank will work just fine

 

The intank will more then do for the power goals. Since he already had the inline I would throw both of them on there just for kicks.

 

Well, I was hoping to get away with JUST an inline pump.

How does the Vortech system work then, don't they have an FMU. With an FMU you need a return line, where do they hook it up. I'd rather not have an FMU.

So there is no need for an FPR then?
