Question Swaping from LT1 to turbo LQ4, how to run fuel?

[Jc803]

Hey guys, I found very little info on how to set up the fuel system on just a NA LS swap. But nothing is coming up for a turbo LS swap. I've already started parting things together and buying a Huron turbo kits in a few days.
I have a 96 LT1 with T56. I have read that guys are using a 00 corvette FPR/filter and puting it on the LS fuel rails. Guys seem to not like this because its "tacky" with the stock fuel lines, so they relocate it to under the car. I have actually relocated my lines, and dont mind having the FPR connected to the fuel rails. Wouldnt be so bad with my lines. Heres a pic.

Will this work? Do I need any fittings? And biggest question, do I have to somehow make the fuel PSI vary with boost psi? If so how would I go about this? Would I still go with the corvette FPR or a different setup?
I understand the fuel line feed and return are different sizes than the corvette FPR, but where would I find adaptors or fittings to make it work?

Ok, so, I posted this in three times in two sites and nothing.

So what I've found out on my own is, with a turbo setup you have to have a boost referenced FPR, and a return line. Thats hard for the LS guys because they dont have a return line so they have to make it. But I already have a return line. So does this make things easier for me? Any ideas to get me going?

What are you looking to make with the turbo setup? What fuel pump are you gonna run? When I was tossing around the idea of a turbo setup I decided to sump my tank and run an external. Some guys run dual walbro pumps with a custom hanger. You are correct about the fpr most increase at a 1 to 1 ratio. Depending on how much power you wanna put down and how much boost you want to run you should probably run new fuel lines. This is what I planned on doing. I was going to run -10 for my pressure line and -8 for my return which was a bit overkill by some opinions but at the time I was looking at running the a1000 with a pretty radical setup. As far as setting up the fuel system I would run the banks parallel if at all possible instead of running a series setup like the lt1 fuel rails are.

Thanks for the info. I've had a lot of replies on my other thread on LS1tech but still have some questions, plus coming from a guy that originally had an LT1 could give me better advice.

I went on aeromotives web page and look at their hp chart and what they recommend. I want to make about 650rwhp to start out and eventually forge and shoot for 1000. On the hp chart they recommend a A1000 fuel pump, AN-10 line to filter, AN-10 line from filter to a Y block, AN-8 from Y block to fuel rail, AN-8 from fuel rail to FPR, and AN-6 from FPR back to tank.

A few questions.
1. Where would I get this AN-10, -8, and -6 line?
2. Would I use a Y block?
3. On the same chart they recommend either a 13101 FPR or 13109. The 13101 uses AN-10 inlet and AN-06 outlet. The 13109 uses a AN-6 feed and AN-6 outlet. But in the chart it says AN-8 from fuel rail to FPR so neither makes sense. Which would you recommend? Both operate at 40-75psi.

If I'm just making 650rwhp for now, would the stock hard lines with my stock size braided lines and the 13109 FPR work? How much hp can I make with the stock lines? Some are saying anything from 500 to 1000

You know what, scratch the 1000hp idea. I just want to run 10's at an 3,800 ft elevation. So assuming I can do that with around 650rwhp, what set up would you recommend and where would I buy the lines. Maybe AN-8 feed and AN-6 return. Also how big is the line coming from the fuel pump? If its small that AN-8 I would imagine that would be the weak point if everything else is AN-8.
