confused on my turbo once again...

[tpunx99GSX]

so again i am having trouble figureing out what turbo i have.
I bought it off of a kid on tuners a year or two back. i absolutly love the turbo but have been having trouble determining which turbo it is.
At first it was listed as a Turbonetics 50 Trim.. but then about 6 months after i had gotten it i happened to take the turbo off and see that it says Precision Turbo and Engine on the exhaust houseing, So at that point i was like "Oh i guess its a PTE turbo." Now there is a Turbonetics sticker on the backplate of the compressor housing but i figured that was just a turbonetics backplate that they sell on their site. but then i was looking at the turbo again yesturday and noticed that the center section of the turbo has the turbonetics logo on it.
So now im really confused because turbonetics doesnt sell a 50 trim.
Anyone know which turbo i may have, I can measure the wheels if need be just let me know which measurements i need.
This is a picture of the turbo next to my old T28 from when i put that on my GSX.

looks like any RS49 if it is a Turbonetics piece.

Looks like a cut PTE turbine housing. Unless Turbonetics uses a similer housing mabey a Tubonetics turbo with a PTE turbine housing?

Yup, it's probably just a cobbled together bastard RS49 w/ PTE turbine housing.

I know some of the places were buying housings from PTE back when they were the only place that had them. Maybe Turbonetics did that for a bit?

You could take the compressor cover and exhaust housing off and measure the wheels and look up on line or call turbonetics with part numbers to see what it is. It looks like a 50trim size compressor w/ To4e cover with a stage 3 exhaust wheel .63a/r. The turbo seems to work good for your setup so if you can not find out what it is its not a big deal.
