Getting the truck boost ready...fuel questions

[oleshifty]

It's about time to start making the truck faster.

I want to get a Walbro pump/tune/(injectors?) from Nelson, and am going to FINALLY get rid of this handheld tuner.


Questions 1) is there a HOW-TO thread anywhere for the walbro pump? Where to cut, how to wire it-in, etc? I've searched and can't find much besides "cut the bucket to make it fit" and people having issues with wiring come undone. Are people soldering these and putting small fuel hose over the wires to act as shrink wrap? The truck is a daily driver, so I can't be having "reliability" issues. It has a 163k miles on it, so I want to at least get the parts ordered before something goes bad.


Question 2) is there really any reason to buy new injectors NOW? With tune/intake/exhaust/ud is there anyway I'm maxing out my stockers? I want to put a turbo on the truck within the next 2 years, so I know I'll need them eventually, but is it worth putting them on NOW, or should I hold off? Does anyone make a direct fit upgrade for fuel rails? Reading on the Honda boards, people were making decent power increases on completely stock motor by upgrading rail. I know the LS motors are a completely different beast, but trying to get all my bases covered now.


I want to upgrade the pump/tune to get what I can out of this motor N/A. Once my trans goes, I will be throwing in a FLT/stall (what is recommended for boosted applications?) , and THEN I will start the turbo build. It's pointless to do it now, my trans won't make it down the block.

As far as the walboro goes you will have to cut the bucket but i just used red butt connectors and have had no problems.

And for the rails aeromotive make some for the ls6 and u just have to make ur own brackets to bolt them down. I used some aluminum angle iron i bought from lowes and just cut it and drilled a couple of holes to mount to. But when u change rails u will need to get a pressure regulator because you will be taking the factory one off with the rails.

and for the injectors u can put them on now and u may notice a little gain but if you are not running a cam then u shouldnt be maxing out your factory injectors.

If you want i can take some pics of my setup tonight to show you

ya that'd be great. Thanks!

i bought a set of professional products LS1 fuel rails and used the ls1 brackets for the truck manifold, all i had to do was bend the brackets slightly to rest on the plastic bridges between the intake runners, then i just drilled a pilot hole and put a small screw in each bracket fasteneing it to the intake.

Why is everyone swapping fuel rails? The stock ones ca n handle 1000 rwhp.

[dropem]

They are 60# from Nelson not sure what brand they are

but there are several reasons to swap rails on a boosted app they may flow enough to in theory support 1000 hp but for one have u looked at the cross tube it is tiny and another is for the fact that the regulator on the rails are only vaccum refrencing and doesn't reconize boost like most after markets will and also have the ability to adjust pressure and it just doesn't make sense to not upgrade them with a aeromotive 1000 and braided lines from the tank forward

yeah I havent swapped my rails just yet
