03 Turbo swap Help

[BrownieHeavyHauling136]

I have read all the threads I can find on how to swap a stock 06 turbo to a 03. I bought the turbo and pedistal, but I cant find any detailed lists on how to remove the old one and install the new one. Any info would help. Thanks again

There are 3 10mm bolts that hold the turbo on. To get the front two I like to use a 10mm box-end ratchet and for the rear you will wanna reach over the downpipe from the passenger side and straight down. Gonna need a 10mm socket and a long ectension, feel for the bolt and try to set the socket on it then click the wrench on. Remove clamps fom DP and inlet pipe, oil line and CAC tube, to remove lift up and toward passenger headlight.

Ok and as far as putting everything back on all the hoses and pipes should just go right on and tighten up.

why would u want to buy a worse turbo cause it sounds cool???? makes no sense to me to go from a better turbo to a worse 1

Only real difference between the two turbos aside from the noticable wistle is that the later turbos have a coating on the unison ring to help prevent sticking vanes. Nothing really worse about the '03 turbo in my eyes. Just make sure you clean the turbo up really well before you put it on your truck.

The journal bearings increased 1mm in size from the 03 early 04 turbos. Helps with reliability. The better VGT builders prefer the later turbos for building modded ones due to this, and also because the 03 style wheel can simply be used in the newer ones for the reduction in backpressure(almost insignifigant), as well as the whistle.

I believe there is some kind of groove in the 06-07 turbos that helps with the draining....cant remember for sure but I think I read that somewhere...its supposed to make the VGT more reliable...
