    New turbo, no power

    Tonight I put my hand pump on the wastegate actuator. It took 28 psi before the actuator even started to move, so it has to be exhaust pressure forcing the wastegate open, not boost pressure. I put two more turns of preload on the actuator which raised the opening pressure to 30 psi with my...

    New turbo, no power

    Here's a picture of what I did. There is no port on the housing and it's too thin to drill and tap, so I took a 5/16 bolt and drilled a 1/8 hole all the way through it. I drilled a hole in the hose directly in front of the compressor housing, put a washer with o ring on each side, pushed the...

    New turbo, no power

    I'm referencing the wastegate directly off the hot side of the turbo too. There is no boss for a nipple on the turbine housing and the housing is too thin to drill and tap, so I made a nipple by drilling a 1/8 hole straight through a 5/16 bolt, drilled a hole through the hose directly off the...

    New turbo, no power

    I can't say the timing made any noticeable difference because the wastegate was preventing it from building any boost. Once I figured that out it helped a lot, but I'm still not sure what is actually normal. It seems strange even with the heaviest spring it still won't go over 15. It's tight, I...

    New turbo, no power

    I have 3.55 gears and a ZF. I think I'm running around 1800 at 55. I have the stiffest spring in it now. I'm going to have to put my hand pump on and find out exactly what pressure it's starting to open at. The only adjustment left is tightening up the preload more.

    New turbo, no power

    I spent almost the entire day fighting with this thing again. I got the timing meter Thursday and got timing dialed in about 8 degrees. I also took the slip pipe apart and packed it full of copper RTV a couple days ago. No exhaust leaks now, but it would still top out at only 6 psi when I test...

    Injection pump timing

    I just bought one of those myself from the same seller and it arrived yesterday. It looks like everything you need should be there. I'm going to try mine out this weekend.

    New turbo, no power

    I bought the timing meter, it should be here by Friday. I'm going to try messing with it again this weekend.

    New turbo, no power

    Will this timing tool work or would I need a different adapter for it? It says its for a 6.2 or 6.5 GM but they use the same size injector lines...

    What did you use? The copper rtv?

    New turbo, no power

    So, how do I set ATDC? I know where the zero mark is on the timing tab, but all I can do is dial in degrees of advance on my timing light, no negative adjustment. How do I read this correctly?

    New turbo, no power

    How did you seal it? I know I have a small leak around the slip pipe fitting on the Y adapter. I can hear and feel it leaking around that connection but I'm not seeing any soot around it. No boost leaks. I pulled the hose off the hot side of the turbo and removed the boost gauge line, then...

    New turbo, no power

    I used a Snap on MT254 and followed the instructions on the back. This morning I moved the pump back toward the driver side until the scribe marks were aligned. It's better, but still not right. It is more responsive now, starts easier and runs quieter but still will not build over 6 psi under...

    Not yet. Thought I would get more opinions here.

    New turbo, no power

    I finally got my new turbo install finished today. It's a CDD GTX 3852 with intercooler, 110 pump and stage one injectors. I used a luminosity probe and set the timing as close as I could to 8 degrees at 2,000 rpm. It was all I could do with two prybars to get the pump advanced that far, it's...

    "New" superduty woes

    Have you tested the glow plugs? Unplug all of them, clip a test light to the positive battery post and touch the tip of each glow plug with the test light. If the light comes on they should be good.

    How much boost?

    How much is safe on stock valve springs? I have studs but decided against 910s because I don't plan on running this thing like a race car and I don't care for the added stress and wear on the valvetrain components so I shimmed my original stock springs back to factory specs.

    Can anybody tell me what this noise is?

    Lug nuts all tight? I've heard a similar thumping noise from loose lug nuts.

    what doors fit?

    I remember seeing this discussed before on a different forum. As I recall the 80-86 doors will work on 87-96 trucks, but not the other way around. Something with the contour around the lower rear corner. I'm not sure how well they fit, but they are supposed to work. Edit: found it...

    DB2 vs DB4 pump

    If I could start over I would have gone with a Cummins swap.

    Somebody better buy this truck!

    Radiator too tall and doesn't fit? No problem, just cut a hole in the hood! ;Sweet https://www.facebook.com/marketplace/item/1554488904736248/

    ZF5 swap - Another throwout bearing question

    I put the Luk kit in mine and tossed the junk bearing that came with it. I replaced it with a Timken and no issues so far.

    So what did you do with your truck today?

    My pyro probe adapter arrived today, fits perfectly so I was able to finish the gauges. Still dead in the water with this intercooler though. I've been waiting over a year on these parts and I still don't have everything. All I can do now is try to patch the rest of it together the best I can...

    Little Trick for Fan Removal

    I bought one of these years ago: https://www.amazon.com/Lisle-43300-Pneumatic-Clutch-Wrench/dp/B000JFJLTC Its all I ever use. All it takes is a quick jolt with the air hammer and its loose. One of the best tools I own.

    Pyrometer probe depth

    I finally found and ordered this: http://thesensorconnection.com/egt-probes/compression-fittings-and-mounting-hardware/egt-probe-compression-fittings-14-npt-thread?keyword=&gclid=Cj0KCQiApsiBBhCKARIsAN8o_4iSK0PTD7TMELmFvUz4WBWsxUxANoIniodSsiZ4kNauhJtuMMSIcWMaAvJFEALw_wcB That should be what I...
