Vgt on 5.9's

[CBari]

Is anybody putting the vgt from the 6. 7 on the 5. 9 and using them to full extient. I. E. the exhaust brake function also. I would assume that one woulld have to run some aftermaket controller for the turbo.

I have the HE351VE sitting in the garage, I am just waiting on funding for the rest of the install. Fleece Performance makes a controller that allows for the EB function for $695.

You need a 6. 7 turbo, exhaust manifold, and exhaust elbow. You exhaust will be a direct fit. The intake may take a little modding as the turbo is longer on the compressor side, but a 6. 7 setup should fit if you want the stock look. For the oil lines I am not sure if the HE351 stuff will work or not, coolant line can be done how you want but I will be running a steel braided line from my heater core return thru the turbo and into the water pump.

Do you know anybody that has personal done this mod and have the been happy and has it been trouble free. I would assume that you should have the sooting trouble with turbo like the 6. 7 do because we don't have the EGR.

I don't know anyone personally, but there are quite a few folks running the Fleece controller and are quite happy with it.

AH64ID, just wondering if you could explain how this kit and turbo would go together and how it would operate??

From what I have gathered from Fleece the controller plugs in the Data Port on the block. From this it gets Load, MAP, TPS, etc... The Controller then adjusts the vanes on the VNT to match your current conditoins. The controller is user adjustable if you want to change how it operates. . say if you tow a lot, or want to use the HE351VE for twins (like I am considering). .

Then you have a in-cab dial that allows you to run the controller in full auto, or auto with input to open or close the vanes more than what the current conditions call for. . Say your towing and you want boost to build sooner and stay higher, well you can tighten the vanes up, or your cruising empty on the interstate you can open the vanes to drop boost and drive pressure to see slightly better mileage.

Then there is the exhaust brake, with the EB option you have a switch that runs just like any other EB out there.

Fleece also said they are working on a warm-up mode, so when coolant temp is low the vanes will close (user can adjust how far) to put a little more load on the engine to help it warm up faster.

The HE351VE is a 60/60 just like the HE351, but the housing is variable from 3-32, where the non-VNT HE351 is fixed at 9cm. So the overall airflow won't change much, but the adjustable housing should allow for faster spool, and reduced drive pressure at a given boost pressure. . which hopefully leads to slightly lower EGT's.

Am I missing something here when I go to their web site I don't see anything on a controller for the cummins 5. 9 just one for the durmax.

They don't have it on the website. Call or email them.
