Looking for info on VGT vs. non-VGT.

MrOneEyedBoh · Apr 13, 2014

With all the talk of higher BP on VGTs versus non-VGTs and potential of the higher BPs causing headgasket issues, it sparked my interest. I tried to search but my terms were either too short, or I wasnt searching the right stuff to get anywhere.

Im going to most likely have my truck in MPD's shop for a stud job and injectors soon. Injector wise would be 190/30-75s, and for turbo I was going to go Barder or KC 68mm.

Now the non-VGT option has be interested in that. I know at minimum I would need the up-pipes and mounting/oil brackets. But other than that, I dont know which combo works well for a DD ( if at all... ), the characteristics etc. I dont mind reading at all, so Im not looking to be spoon fed here. Im just looking for info that anyone has links to, or even your experience/suggestions.

The barder stage 3 seems to do much better than most vgt turbos because he up-sizes the turbine wheel.

I wouldn't say it causes head gasket issues. If mpd is doing the work and you're only running 190s I don't think you'll ever have an issue no matter what. I love my 66 but the lag isn't for everybody.

Barder 68 and 190/75s and let her eat. Be ready for a trans though if you don't already have one.

What's your goals?

if its a dd i'd stick with a vgt turbo, unless your want it to be a weeknd warrior type deal. make sure u hasve the fuels system to keep injectors fed and as stated above ur trans will need some attention either way unless u get a tune written to be nice on ur trans.. a smaller less power tune.

& for the non vgt , i would reccomend divided T4 up pipes & a divived T4 housing on the turbo

I want to be around 600. Trans I do know about but I'm praying to the powerstroke Gods that my stock trans lasts until next year tax refund time. I know they can go out whenever, mine has 51k on it currently.

As far as fuel. I'm going to run the driven diesel RR and i have a new hfcm pump too. I'm also hoping I can hold ICP too.

If it makes you feel any better my stock pump is dropping pressure on 190/75s and I lost my trans in 3 weeks.

Hahahahah thanks bro!

Well **** happens.. That's one reason I'm skeptical about 190s.. 175s are pretty much a guarantee on holding ICP and FP.

And 175s can get to, well almost get to, 600.

I'm running a ported intake too, hoping to maybe get something there too. And I'll be running FICM tunes too

ICP is a non issue if your pump isnt dead with anything up to 210s from us. Anything more than that and ICP starts to fall off.

Fuel pressure is a different story, i see stock trucks with a reg return and new pump drop fuel pressure on stock injectors and tuning.

Sump and fresh filters then go from there.

Haha mine is having an issue holding 65 now with blue spring... Not s good sign haha. I'm hoping RR will help

Anthony, by the time you figure out on what mods you want to do it will be time for a new truck! do u have grey hair yet from all this stress your going thru?

just playing as always- got my stage 2.5 kit from nate. might be a good option for you. Truck rips really impressed with it so far. Call me sometime will ya?

Right now my KC Turbo has the largest turbine wheel ever installed in a 68mm vgt. It is something that Charlie and Nate is trying out. Its got a polished .72 race cover that no other builder uses. Here's my KC billet 68. I think by far the best looking reman vgt out there I think!

04cr450 · Apr 13, 2014

^ that's basically the same setup I have. except the 2.5 kit has a different turbine wheel. But same polished cover. Stay tuned for updates- so far the turbo hauls some butt

I have a barter 68 and with in two weeks roasted my direct clutches. I have full force 190/75's and was dropping icp pressure but my stock pump was a little hurt so I got a Terminator T-500 and it's holding pressure great, bad ass pump! My stock fuel wasn't even holding stock injectors with the blue spring all that great so I did a Holley Dominator billet pump with a sinister regulated return and its holding fuel pressure fine.

MrOneEyedBoh · Apr 13, 2014

Yeah more setback haha. I guess I'll have to figure something out fuel wise. Hoping I can detune the injectors until I can get the money for the trans.

That's a good looking turbo!! I like the race cover!
