Mod stock vgt to 68mm review

Well... I am always messing with something on my truck and I was shopping around for a new vgt turbo. I was running the MTW stage 1 and it was just a little too smokey for me. It ran great, pulled hard, spooled quick (i have nothing but good things to say about MTW) but I didnt want to have to pull fuel to compensate for the turbo being over fueled.

I tried searching around, I did not want to go with non-vgt, I wanted bolt on, I thought the stage 3 was too big, hybrid was not enough gain over stage 1, and I was on a budget.


Well after searching I found someone that can mod a stock housing to fit a 68mm compressor wheel. I was doubtful at first but after talking with him i told him to go ahead and make me one. I got the turbo last Thursday and I have been driving it around since and I wanted to post my review.

The Good:
This thing pulls hard and definitely takes advantage of the 175cc/stock nozzle injectors. My truck would smoke like a freight train before but now on a full race tune it clears up the smoke to just a slight haze. My EGTs are down significantly. Sometime I have to be careful with my tune (extreme X) because if I accidentally hit the lights switch area of the throttle the truck really takes off and makes me press the pedal even harder making me go faster. I got my first speeding ticket in 5 years this weekend while playing around with my new turbo.

The Bad:
There is a slight bit of turbo lag... I would not call it laggy at all but the stage 1 spooled SUPER fast. With my driving habbits I don't even notice it very much, but if I try I can tell it has a little bit more lag than MTW stage 1. Also if i roll into the throttle very slowly to make sure the truck does not down shift (lugging the motor on purpose) i get turbo surge. I never get surge when getting on it hard and/or with normal driving. I did not even get any surge for the first few days until I tried testing out all of the different scenarios for the turbo. Right now I am just running my MTW stage 1 tune. I am sure once i get my tune from Eric at IDP that I will not have any problem


One thought that I have is how the 13 blade turbine affects the turbo. I know a couple of people (mostly RCD) offer a 68mm powermax with the 10 blade turbine but this build uses the stock turbine (for my truck that was the 04 13 blade)...

Also I have read fears of the large compressor wheel causing premature failure on the shaft/bearings. I guess only time will tell.



So far I am super impressed but I have only put a couple hundred miles on it. I am taking a week off work and heading to vegas with the wife so I will see how it does on a long trip.

Well I don't want to go too much into the company or price because he is not a supporting member/vendor here on powerstroke.org and this was a review thread not a sales thread ( mods please don't ban me )

But just talking in general... I searched a lot on the internet and found a couple of different options for this turbo upgrade ranging from 900-1800 (depending on the vendor and if you supplied the core or not) I bought mine more near the bottom of that range and I supplied the core

no pics yet... I was too excited to put it in. Not much to see... except for a big cast compressor wheel

On that note... windrunner does MTW sell a single plane billet 68mm wheel upgrade?


Also please excuse my ignorance if this sounds like a stupid question, are all 68mm wheels created equally, or in other words would any 68mm vgt compressor wheel fit my turbo? I know the duramax guys have a few different options for billet wheels but I would love to get a billet single plane just like in my MTW stage 1

I got ya man. Well I know Danville sells a 6x6 billet wheel made by bullseye that will fit and I know of some other places that sell a 6x6 wheel that will fit.

I am not certain whether our billet wheel will work or not in your turbo. I say this because we have not been able to bore out a Stock turbo compressor housing large enough to accept a 68mm wheel. We keep cutting through the shoulder on the inside of the compressor cover. So this leads me to believe that our wheel may have a slightly different shape to it than the wheel you're using. We've done the measurements and if you one is able to cut a stock housing to accept a 68mm wheel without cutting through, then the material must be really thin.

Hope this makes sense man.

thanks for the informative reply

A couple more questions:

Is the pmax housing bigger than the stock housing (is that why they accept the 68mm easier)?

Is your 68mm wheel single blade and billet? Could you send me a price through PM?

The Pmax housing, while the same A/R (or space inside the turbo), has a significant amount of more material than the 04-07 stock turbo compressor housings do. It is also actually a different shape to it inside than the stock turbo compressor housings.
