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.
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.
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.
