Re: 85 lwb turbo 5.3 build
 

There is no way I am putting painted headers on. One trip around the block and they will be bare. And I may be putting a turbo on it still. Not looking to spend lots of money on something I am just gonna take off.

my LY6 manifolds are just sitting in the storage building. a bit heavy to ship tho. I'd take a lil' trip in the old truck for fun if I had the vibration fixed (for which I have a plan)..... if you weren't so dang far. :lol:

to give you an idea of how they fit:

Got some done today. Got my tps, iac, and fuel rail fittings in the mail today. Removed water pump and installed the ls1 intake.

I ordered some more parts to night. Ordered a throttle cable and bracket and bolts. Also ordered a throttle bracket to my suburban. Nally buick online parts is a amazing web site. Great drawings of the parts and good break downs. Also got a seat belt bracket for the wifes new gmc.

Re: 85 lwb turbo 5.3 build
 

I was looking at the vette fuel filters and i was thinking about the way i need to run the fuel lines. One from tank to pump to filter. one from filter to tank. The one from filter to rails and a tee on the passenger side rail that a short hose goes to driver side rail. Will that work?

Re: 85 lwb turbo 5.3 build
 

drawing.

Re: 85 lwb turbo 5.3 build
 

I don't think you need to loop the system like that, just in the pass side fuel rail, out to drivers side rail, and a plug the end....not "tee'd" back in.

Re: 85 lwb turbo 5.3 build
 

I was thinking the same but I already have the fittings and hose. It should look cool with the extra crossover in the rear.

Re: 85 lwb turbo 5.3 build
 

If you're going with a turbo setup, I'd strongly consider putting together a return style system with a regulator up near/on the fuel rails. Much better setup for a turbo with the boost referenced regulator.

Re: 85 lwb turbo 5.3 build
 

Yes if I do put a turbo on it will for sure get a return system. But I can't find a decent priced fuel pressure regulator. The lowest I found was over 100 bucks. If I can find one around 50 that is what I will use now instead of the vette fitter.

The stock truck setup works great. It's not as pretty since you need to use the truck intake instead of the LS1, but it's VERY cheap, and good for around 500-550 rwhp.

Re: 85 lwb turbo 5.3 build
 

The harness I have has car set up with wire routing and injector plugs.

Re: 85 lwb turbo 5.3 build
 

So what pressure does the regulator need to be for. Will a 30-65 psi work? Many them things are expensive.

Re: 85 lwb turbo 5.3 build
 

Your fuel pressure should rise at a 1:1 ratio with boost.

Example: If your base fuel pressure is 58 psi, at 1 psi of boost, it should be 59 psi and at 10 psi boost, it should be 68 psi.

Doing it this way makes it easier to tune, since your injector flow should remain constant.

Re: 85 lwb turbo 5.3 build
 

Ok i will order that fuel pressre reg that i seen cause it will have no boost for a while.

On a side note i got in the cold air intake kit today. Looks like a nice kit.

Re: 85 lwb turbo 5.3 build
 

Test fitted the intake today. Also installed the egr plug. Not sure on where the intake pipe will end up after the water pump and hose is installed but this is where i want it to be so far. Need to order the rubber clamp that the maf goes in to mount the air filter. Got the part number already just have to call the local gm dealer.

Re: 85 lwb turbo 5.3 build
 

I got the gen 4 water pump in the mail this weekend. Test fitted it and it is like it was made for the swap. Fits like a glove. Also figured out what i am going to do with the intake pipes. I put the belt on just to make sure the intake pipe will fit around everything. All i need now to test run is the fuel system.

Re: 85 lwb turbo 5.3 build
 

I got the throttle cable and brackets i ordered the other day finally.

Re: 85 lwb turbo 5.3 build
 

I had a slow day at work so i figured i would see if i could drop the factory tank. I am not going to use it anyways. I am going to put a cell in the rear frame area. The factory tank had way too much crap in it for me to use. I jacked the truck up to get under it and proceded to remove the pos plastic skid plate that goes over the tank. I may have found why the truck leans to the driver side. I pulled the shield down and a bout 30 pounds of crap fell on to the floor. And the bottom of the tank is rusted out i am sure. I am fully confidant i can put a screw driver smooth threw the bottom of it. It smelled like fuel and was damp. I gave up for the day due to dinner time coming up and i could not remember how to remove the tank. I now know there are 8 bolts to take out and the tank will come out with the brackets and all. May takle that this weekend. Boy am i happy i did not want to reuse that pos.

Re: 85 lwb turbo 5.3 build
 

Made some good progress today. I removed the fuel tank then the bed. I will never know why in that order. I also figured out why i was always getting crap in my fuel filter. Fuel sock had a hole in it.

Re: 85 lwb turbo 5.3 build
 

Love the progress man! I am doing basically what you are. I may go turbo in the future, or 383 with H/C/I. What is the part number for the water pump you used? I'm going to use an LS6 intake on my 5.3 if I can get one reasonable.

Re: 85 lwb turbo 5.3 build
 

On idea on the part number. It is a 08 gmc water pump. Got it off eBay.

Re: 85 lwb turbo 5.3 build
 

Part number on that pump should be 19208815

Re: 85 lwb turbo 5.3 build
 

Ordered my hole fuel system today from tank to fuel rails from summit. also ordered flywheel from advanced addapters. Hope to have it running soon.

Re: 85 lwb turbo 5.3 build
 

What hose and fittings are you using? I need to do the same, just don't know what fittings I need to connect AN hose to the 87 sending unit
