Re: 85 lwb turbo 5.3 build

Made some good progress today. Installed the intake, harness most of the way, passenger side manifold is in, ecm is mostly in, heater hose are cut and test fitted, brake booster line and pcv lines are done. Not a hole lot left to do. Just need a few more things and it will be time to fire up.

Re: 85 lwb turbo 5.3 build

Got more done today. Removed driver side collector cause it is hitting the frame. I need to have it cut and repositioned. Installed the batt cables and ran the ECM power wire. Cranked the motor over a few sec to test the starter. All I need to do is get o2 sensors and wire up the fuel pump and flush the lines. Will post pics later.

Re: 85 lwb turbo 5.3 build

Got it started today. Ran under a min. No cooling system yet. My oil psi gauge is not working in my dash. I disconnected the sender from the harness and put my volt meter on it and off it read .8 ohms and on it was like 55-60 ohms. So it has pressure. I also seen oil coming out the push rod when I took the oil cap off of it so it has to be my gauge. I grounded the wire out and the gauge did nothing. It should peg out unplugged or grounded correct?

Re: 85 lwb turbo 5.3 build

Got more done. Got the cooling system all set up. Got the power steering hoses and fluid in after taking the bracket on and off about 45 times. All I have left is finalize the wiring and I am sure there is more.

Re: 85 lwb turbo 5.3 build

I am almost done. I secured the fuel lines and fuel pump power wires. Got the break line secured after removing the factory fuel lines. I have all the wires secured and ran except the fan and one o2 sensor cause the collector needs modified to not hit the frame. Also need the speedo wires hooked up or removed. I have not decided what I am going to do with that. Ran the motor and I don't have any coolant leaks or power steering leaks. I did have a bit of trouble getting it to burp all the air out. It tried to over heat for a little then it finally started pushing water threw the top hose. But it is working good now. I don't have a fan on yet so could not run it too long. I am pretty happy with how it runs so far. It did not die when I blip the throttle like my burb did. Cant wait to drive this thing.

Re: 85 lwb turbo 5.3 build

That video barely sounded like you got to 4k, sounds like the boost didn't hardly have time to kick in! It sounds good but I can imagine that once you actually start to draw some air it sounds entirely different.

Get her out on a nice long street, I want to hear this thing under some load where we've got noticeable boost. The little 5.3's SCREAM under boost, like a pissed off snake. It's gonna be sweet.

That will teach me to jump from my last post to your last post without reading a bunch of stuff in between haha. No wonder I can't hear it!

It still sounds good though, and now that I've actually gone back and looked at everything, its pretty clean too. Hopefully you'll get back at the turbo tho when the time is right, gotta execute the original plan!

Re: 85 lwb turbo 5.3 build

It will get some kind of forced induction when money comes to me. Had to get truck going. Will need a trans before too long. Then a bigger rear end.

Re: 85 lwb turbo 5.3 build

It has been a while. Still slowly getting parts. Ordered a better fuel filter due to crap being in the lines and tank. It was plugging the old one fast. Got most of the junk out and put a much larger filter with a better element in it. Also my bed bolts came in. Now to figure out what I want to do about putting a hole in the floor that I can fill the tank up with and have covered. Running out of ideas.

Re: 85 lwb turbo 5.3 build

Since this is going to be a daily driver if I were you I would either make a pan for the fuel cell or make a container it can sit in to protect it all the way around. Those cell's aren't really made for the application you have.

Re: 85 lwb turbo 5.3 build

Thanks. I can't wait for them to break in or what ever they do and be louder. Every flowmaster I ever had has done that after a few weeks.

Thats weird...since they are chambered and all steel inside...nothing to break-in like a glasspack with the fiberglass matting inside...

Re: 85 lwb turbo 5.3 build

Got my ECM back from lt1swap.com guy and it now idles nice and low like it should. Does not push hard when sitting at stop light. Much better to drive. Just need to get trans shifting correct with shift kit I hope. Then I may get a set of wheels. Wife wants showwheel streeter in black. Possibly 18x9 in back and 18x8 up front.
