Yeah that was my thought. I will be tearing into that over the weekend. Hopping that the injectors are lose or the orings are bad and not the cups.

 

Could be one of the copper crush washers too. Bob mentioned it before, but I would inspect ALL 4 injectors on that bank, if one leaks it can simulate others having issues too with it leaking back into the "rail" if you want to call it.

 

All right I pulled both those injectors as well as the ipr and everything looks good. I am going to pull the other 2 on that side in a minute. Crush washers look good orings look good and are new bolts where tight. Ipr screen was mostly clean and not brocken but I have a new one to put in as well as an icp sensor and pigtail. Was looking at the injector wiring harness and one of the ficm side plugs is cracked. Will replace that as well. Talked to Warren Diesel and he wants me to send the two injectors that threw the code back to him. I tell you what he and swamps stand by there products all the way. I also ordered an sct tuner, believe its the 3000 part number with the custom written maps. got that so when I put this truck together and it runs right I can get new maps for the new turbo and fuel system.

Hmm since I have your guys input for now, what turbo would you run with an automatic? Was leaning towards an 03 turbo from liberator diesel. He has them I believe they are his stage 1's. The way he explained them is they are a new turbo 2003 style with a modded wheel. Wasn't certain that would be better than a less expensive garret powermax but he also sells those at the same price as everyone else. I would rather buy something from someone on here if you recommend someone.

That is a video of my truck when I picked it up I took it for the shop, I was trying to be nice. It was warmed up and had some very bad turbo lag and was stumbling all over the place. Was thinking since orings and copper washers looked good maybe cups? Maybe this will help.

 

Might be an internal issue with the injector, it'll be interesting to see what Jesse says.

155's and a stock nozzle probably wont flow a ton, a powermax would be fine, or find an 03 turbo used on the forums.

Maybe look into the Mad stage 1 turbo too, it's cheaper than those and will outflow those.

 

Thanks for the info. Yeah these 155 shouldn't flow much I am buying a new injector every other week and will be having him run em up to 175 or 190 with bigger nozzles but that wont be for about 6 months should be running back to the east coast before then. Figured having these done would make things a bit more reliable. I still don't want to run a huge turbo. I will check out that mad stage one. I will pull this other side of injectors and see what I find...

 

155's can flow a decent amount, the stock size nozzles would be limiting it. Still an upgrade over stock though. If you plan on jumping up in size, the mad stage 1 or even the stage 2 might be a good choice. Check them out some time.

 

I will do you know there full name or better a website? I was searching bit havnt come up with anything.

 

It's basically one guy doing it himself, not sure they even have a website yet. He's on PSA. I'm trying to get him to come over here possibly. You send in a stock 6.0 turbo and $700 and you get your mad stage 1 back. It's a 6.0 stocker on the back side and machined to adapt the front half of a duramax turbo. Supposedly cleaning up better than the p-max and flows more on top. Also goes by MTW too (Mad turbo werks).

 

That sounds good will have to talk to him. Wonder what the bottom end loss would be? Generally it seems your power has a band width and when you make the top tougher the bottom weakens out. In a quad I would change stroke and cams to compensate for the larger bore carbs a little bit to get it to pull harder. Really don't have that option here.

 

It will spool like stock. It's still got the stock VGT setup from the back half of the turbo. Everyone is raving about them. It would be nice to see a map for this turbo, but if you start reading turbo maps you'll see some turbo's can still spool like stock and flow more on the big end. It's not a naturally aspirated carberated quad motor here, apples to oranges! haha.
