Need help with turbo ID... ***PICS***

[yullose]

This turbo came on my car when I bought it in Feb.

I was told "CPT66 dual ball bearing".

The inlet is 4" and outlet is 2.5"
After pulling it off the car, I found it has a .63 exhaust housing... but I have no idea how to ID the wheels.

Any way to tell by looking at them ?

I don't think turbonetics makes a dual BB, only single.
Looks like my bb66

Well... this is why I'm asking.

Looks like a 66 single BB Ptrim to me..

look on the back of the compressor housing cover... there should be an identifying number on the cover itself - NOT the backing plate. as far as BB or not - look up through the center section and tell me what you see. If you see a small hole - its ball bearing - if you dont, journal bearing HTH

I did notice a small screen fitting on the oil inlet and a small (maybe .125") hole on the outlet side... so I have no doubt it's a ball bearing unit.
As far as single/dual ball bearing, that I don't know.

Here's a couple pics I just took... I assume this is the number you're looking for ?

I agree, same turbo I used a couple of years ago to run my first 10 sec pass
