Re: 77 c10 5.3ls turbo
Truck is looking great. I have that TA girdle as well. Looks great until it oxidizes...
Did you use the 87 sender in your original fuel tank? Im considering dumping my fitech fuel sump and wire/plumb and electric pump in the tank. And those Russell fittings fit right on that sender? |
Re: 77 c10 5.3ls turbo
I did use the 87 sending unit. I had an AcDelco Ep381 pump that mounted right up, wont support what im doing now so I switched it for a Walbro 450. That mounted right up as well. Yes fittings mount right up. I went with the in tank pump because it is quieter.

Have you looked into needing a sump to keep the pump from starving? I found a guy on YT that built around the stock setup using a suction jet pump. Im curious if that would be worth doing on a non-efi tank. |

Re: 77 c10 5.3ls turbo
Nice build! One critique, I only saw one picture of the turbo oil drain going into the timing cover so it may not be an issue. But in that pic the fitting on the timing cover is pointing down (I think) and not optimal. Turbos can be sensitive with the drain and it should be as direct as possible for the best flow. Otherwise oil can backup in the line and go past the seals.
|
Re: 77 c10 5.3ls turbo
When installed fitting is pointed up. Keep the critques coming, this is the first time i've done this and relying on the internet.

Re: 77 c10 5.3ls turbo
He's right the oil drain is a very important part of the turbo but I have a friend who put his in the timing cover like that and has logged 16000 miles without a problem. Mine is in that spot as well, I wouldn't worry about it.

That is the crossmember below the crank pulley so the 90 degree fitting is pointed down. It may be obvious to most to point it up towards the turbo but for someone new they may have a less direct path in mind for whatever reason. Maybe I missed it but I didn’t see the drain in other pics so I posted to be sure. I think we both may have misinterpreted each other a bit on this one, it happens, time to move on, but again thanks for chiming in and I agree he’s doing a great job.

Got the axle installed and drag radials on. Still need to finalize rear diff cover install and brake lines. Should finish that tonight. High 20's here so I have to work an hour or two at a time. Driveshaft and shocks are all that is left, besides final tuning and whatever problems come up. Plan on painting white walls on the rear tires to match the front, but that will have to wait until it warms up. Innovate AFR/boost appears to be working but I still need to read the manual to see if I have to calibrate it.

Re: 77 c10 5.3ls turbo
I may have missed it, but where are you getting all your exhaust flanges/vband clamps/etc from? all ebay? Its that small stuff im having a hard time deciding where to buy from...
|
Re: 77 c10 5.3ls turbo
Mostly Ebay but did get some stuff from Amazon as well. I went cheap on the wastegate and wish I wouldn't have. Ended up buying two cheap ones, messed up the first one, both are junk but Im using one of them. If I get to the point where I am using a boost controller I will step up and buy a quality wastegate. At this point I'm just using the 7.5lbs spring. The Ebay BOV, turbo and intercooler are nice.

Re: 77 c10 5.3ls turbo
Took it out for the maiden run this afternoon. Went pretty well, got a couple things to work out.
- Finish exhaust because in ends under the bed now and is loud. - I think im running on 7 cylinders, idle seems a little rough and have an injector error code. Got it up to 5lbs boost and it kept breaking the tires loose. Not to surpised since it is 40 degrees and the road is wet/dry. I think it is going to be ridiculously fast once it gets dialed in. Makes that turbo spooling sound I was hoping for. And blow off valve sounds awesome. |
Re: 77 c10 5.3ls turbo
Nice work overall for the budget you set. My son did one on an '85 and loved it.
One question, I see you used the Hooker turbo manifold on the passenger side, but what manifold did you use on the Driver side? Stock truck manifold? |
Re: 77 c10 5.3ls turbo

I did used the stock manifold on the drivers side. I blew any budget out of the water, I didn't go as cheap as I had anticipated. Although my budget going into the project didn't include any transmission or rear end work. I'm guessing I have $5k into it, engine/tranny/rear end.
Picture of exhaust which I finished last night. The exhaust is my favorite part of the project. |
Re: 77 c10 5.3ls turbo
$5k isn't too bad. I have more than that in my bbc, trans and rear end and it doesn't make any power.. haha.
|
Re: 77 c10 5.3ls turbo
Correction . The $5k is the turbo/tranny/rear end. I had done the LS conversion previously. Much of the LS conversion costs involved stuff I ended up having to redo. Exhaust, fuel system, tranny stuff, driveshaft, computer, etc.. I think if I had started with an empty engine bay I would be into it $6.5k.

Re: 77 c10 5.3ls turbo
Very cool! I cant imagine driving one boosted. N/A run awesome as it is lol

Re: 77 c10 5.3ls turbo
Will you post a picture of your fitting. Each fitting comes apart. You place the insert on the tube and then thread the fitting onto the insert.

Re: 77 c10 5.3ls turbo
Thats the fitting. I dont remember my steel line having two ridges. Glad you got it handled.
