6.0 Turbo Identification

[bigfords]

I'm working on a neighbors 03 6.0, and I'm trying to ID the turbo. Its got a Garrett, stock appearing turbo, but the inlet on the compressor side has got to be around 4" in diameter. I realize the 03s had better flowing turbos, but unsure if this is one or not. Does a PowerMax look stock appearing?

Garret makes stock turbos

Its stock

But yea I'm pretty sure that pmax still looks stock

all stock turbo compressor inlets are 4", The stock intake tube is 4"

ok, thanks guys...I wasn't thinking those inlets were that big. The truck sure is laggy though, I thought maybe it had a bigger compressor than normal.

Vanes are likely seizing

Stock 6.0's aren't exactly snappy off of the line anyways. Tuning seems to get rid of most of the lag though.
