Ok picked up a mystery turbo today from one of my friends who bought it from a guy saying it was a 2.6 turbo. Well after installing it on his 2nd gen 5.9 dodge and finding out it doesn't spool till 2800 rpm he decided it couldn't possibly be a 2.6. So we had another friend measure it at a pull and sure enough it was a 2.8. The turbo has no tag and the only markings are a couple casting numbers on the covers and someone scratched a number into the compressor housing. I have a digital caliper and I'm gunna measure on it some tonight. What can I measure to get an idea on what it is?

Inducer/exducer sizes of both the turbine and compressor wheels will more than likely net you the answers you want.

Or even post pics of it, I'm sure someone will know what it is.

Measured some on it. The compressor wheel is 71mm and the turbine is 74mm. 2.5" compressor outlet. Slip joint. I'll post pictures of the exhaust foot. What are the measurements for a t4?
