Has anyone done this? I was thinking of going to a salvage and picking up a Turbo off a newer 6.7 to do a "Bang for the Buck" type of thing. I was just wondering how much bigger the Turbo is and How much it would help.
I know I'll need to add more fuel as well and I was hoping someone with a little more knowledge would chime in on that too. Would the HR-VP44 be to much or can I get by with a stock VP44 and bigger injectors. Just need some advice, I'm new to diesels, Thanks!

 

Honestly bro, there is no point in doing so. The 6.7 has a VGT turbo, we are swapping 5.9 turbos onto 6.7's.

Yes, a VGT is a major upgrade from any wastegated turbo. The HE351Ve is an HX40.

How much power are you looking for? If you want over 400hp you should look into an HE431 from an MTA11 instead.

 

InsaneDomestics. I am with RSD on this one. Don't know why you would want to go that way... Will not make your 5.9 better.

That is blatantly false information.

 

i like my turbo on my 6.7 since i tow. exhaust brake is nice. most guys want a bigger turbo on the 6.7 for power though but i want the brake. thats the first button i hit after i start the truck.

 

The VGT will spool quicker than your stocker, and still make good power. From a driveability standpoint it would be a good mod especially if you tow. I've seen a 6.7 make over 550hp with the stock turbo.
The first thing I suggest doing to a VP truck is investing in a fuel pressure gauge to keep an eye on your lift pump. VP trucks are notorious for lift pump failures, which in turn kills the injector pump in short order. I would invest in gauges and then look into an airdog if you plan on making more power down the road. An airdog is about a third the price of a new injector pump.

 

lets not forget the control system to make the VGT function properly, sure you could probably set the turbo up so it might work kinda but most likely it will not work properly without some type of stand alone tuning of some sort

 

brayden from fleece performance engineering makes standalone controllers for the vgt turbos.

 

i'm not forgetting that, but last time i heard that was still in beta for the most part, correct me if i'm wrong
