I have a spare 6.7 turbo complete w/ exhaust brake and I was just wondering why it could not work on a 5.9 once you figured out how to make the E-brake work properly.... Does the 6.7 use a different exhaust manifold? I never really paid attention when I had mine....

I think it needs computer control to run the vanes...... otherwise sound idea

mulisha

yup, that aint no swap.what he said

Well, there is just one plug leading to the turbo which controls the E-Brake. At least that's what I thought anyways...

Oh well, I doubt I would have tackled a project like that anyways....

The wires going in control the vanes. The E-brake is the vanes also. When you E-brake turns on, it just tightens the vanes all the way closing off the exhaust. You'd somehow need to build a box that would have boost maps in it that sees rpms, tps, and boost.

I would assume there is a difference between the 06 and 07's that came with factory E-brakes compared to the 6.7's...?

Wasn't Banks supposed to come out with a variable geometry charger as an add on for the 5.9? I think they may have scrapped it, not sure.

There is a difference. The 5.9's exhaust brakes have a butterfly valve placed in the exhaust stream to provide restriction. You can look at BD, Pacbrake, Banks, etc to get a look at one.

As others have said, the 6.7 provides restriction in a different way, it closes down the variable geometry turbine to provide restriction.


I do remember the VGT turbo that Banks was working on. It seemed like a pretty cool deal. From what I can remember it would work with or without their 6-gun. I think it would've been a good thing but they probably killed it because it would've been prohibitively expensive and they probably wouldn't sell too much.


You might could get ahold of these guys and see if they could help...

I know of a few guys that swaped the vgt turbo off of 6.0 ford and put them on the 7.3. I'm shure it could be done but whats the point

On a 5.9 if it could be figured out you'd get a stronger low-end, stronger top-end, and an exhaust brake without having to buy an aftermarket one. If someone could design the electronics to run it, it would be a SWEET swap.

I wonder if Marco could port the programming over from the 6.7's or give us some insight, because I'm pretty sure some of the late 06 and early 07 trucks have the same electronics as the 6.7's...

I've been thinking about this also. After driving my dads 08 and seeing how smooth it is off the bottom end I think the 6.7 turbo would be a great mod to a stock or near stock 5.9. Not to mention the exhaust brake would be great.

someone has got to have some ideas on how to make this work.

You could make it work real easy with some simple electronics, but it won't function nearly as smooth as the 6.7 computer logic controls it.

mulisha

no, but i know a guy who actually ripped out his 6.7 in his 07 dually, and bought a brand new 5.9, modded it and dropped it in. cost almost 27,000bucks

Swapping an HE351VE onto a 5.9L isn't easy, but it's a nice upgrade. The turbine housing is much larger, but still has excellent spool-up on a bombed truck.

The new Holset has a different foot, so either the 6.7L manifold has to swap with it (then you need a pair of EGR block-offs) - you can use the OEM pressure port for a gauge - or you need an adapter for the T3 flange on the 5.6L manifold.
Also, you'd have to install new coolant lines from the heater core return to the CHRA, and back out to the block's water jacket. The exhaust housing flange is also different, so a special mating flange is needed for the downpipe.

The real problem is controlling the VGT.
The actuator isn't a stepper - rather it's a 3P brushless DC motor... so until someone hacks the ST microprocessor running the motor's Freescale control chip (good luck tracing circuits on the multi-layer board!), it's still going to be operating as a BlueTec component, FWIW.
