So a little light came on and I'm just wondering why we couldnt adapt one of these turbo's to our trucks? I know it'll be abit of a pain, but there is alot of upgrade in one of them. For me it'd mostly be the built in exhaust brake.

I'm going to pick one up and play with it.They are cheap and easy to find. I've been looking and havent seen a standalone controler. A bunch of gasser guys are messin with them and controling them with boost actuators.

This was my inspiration, although I used the lesser HE341.

Thats the VGT turbo from the 6.7 correct?

I have been doing some research on using one. They are going to be bone cheap till someone figures out a way to make them work well on the 5.9s.
There was a TSB if I remember right on them also because the exhaust housing and stuff where sticking....so there are lots of them out there cheap.

I think they can work, its just going to take an ingenious controller to make them work right and perhaps bypass the electronic control of the VGT.

Head thats not the VGT. I'm looking at using the HE351VE not the 351W. Although I did read your post...nice.

Yeah there is a TSB on them becouse of excess soot jamming the VGT. Looks like Dodge wants you to run the EB all the time to prevent this.

I'm thinking something manual to control it...do away with the electronics.

Oh dang, my bad.

Wouldn't a manual controller be a pain in the but? You'd have to be continously fiddling with it. The exhaust housing varies from 5 cm to 30 cm depending on a bunch of different stuff which the computer monitors.

Well couldnt you control it with a wastegate actuator? Seems thats what these guys are doin http://www.turbotalk.org/bb/viewtopic.php?f=25&t=4

Sounds like the flange is diffrent also, no big deal really to adapt.

I would think the VGT could be controlled with a secondary TPS, and a WFO switch in the cab, for the goofing off times.
I would be willing to fab one up for my 5.9 if I can find a VGT reasonable somewhere.

the tps alone won't work, if you go WOT at low RPM the nozzle is going to go wide open and be laggy at a minimum.the same goes for a WOT and you lift off the throttle and the nozzle closes with high airflow and shaft speed sky-rockets! IMHO the easiest way is a controller that references drive pressure and boost pressure to maintain a close to 1/1 ratio. BUT you have to watch shaft speed too!

If someone could build a controller that uses boost, drive psi, shaft speed, and tps this should work.

So the guys who replace these turbos on their 07.5+ trucks... what do they switch to?

Ok so I just got 1 from ebay for $150 shipped and might have another on the way for around $100 and I got to thinking. Even if you placed the VGT in a locked position you would have a turbo the size of around a HX40 for $150 bux or so.

I think I'm going to set it up with it in 1 position 9-12 cm exhaust and have it so I could have a 2nd setting as a EB. I'll keep updating this post once I get it, but getting it done will be slow.

BD and ATS and all the big companies already make twin setups for 6.7's.... search youtube. its incredible. theres like 5 6.7 trucks on there making 500HP with nothing but a programmer and twins.

I'm sure they also make nice singles now too, like the 62/71/14 turbo but for 6.7's.

People who haven't even payed 1/4 of what their truck cost are putting on twin turbos and stacking programmers. Where do some people get money from ? go on the 3rd gen forum and look at some of the stuff guys have done to their trucks, making them runs 10's and stuff. HOW CAN THEY AFFORD IT!!
