School me on Turbos !!
~ Looking to be Schooled on Turbos ~
Okay, well I thought I knew a little about turbos. Then, the more I searched and read about them, I found out I didn't know enough. I just ordered 2pc. Exhaust Manifold and was thinking of upgrading my Turbo while in there, but dont know what I have on my STOCK 06 Dodge 3500 Mega 4x4. Lets start...
1) When they say t4 or t3, what does this mean ? Does this mean the ports on where it mounts to the manifold or just simply mount options ?
2) What Turbo (brand) comes stock on a 06 Dodge 3500 Mega ? What (mm) impeller are stock to know what to upgrade ,too ? Any input ?
3) One or Divided ? What does this mean and which should I go with ?
Any help and input is appreciated...

1) see picture below....
2) Holset HE351CW I believe
3) One big housing vs a divided housing. Divided should spool quicker. Also it is recommended to use a divided manifold with a divided hosing and not to mix and match. (see pic below)

Thanks H.R.D.! That info is what I was looking for. As far as gauges go, the truck has none for Boost, Fuel/Air, ect., but they are on the way. Truck was stock when I bought it used, but after a few Mods, it will be a pretty nice truck. Thanks for your input
