How to tell the brand and trim of a turbo?

[Onefast99gsx]

Dam, the compressor housing looks like my PTE housing to a "T" It's even got the 90* nipple on the bottom. I don't have any close up pics of my PTE 50 trim but side by side, they would look identical. What if the turbo you have is entirely a PTE but with a Turbonetics back plate that was replaced for some reason? That's just a guess on my part. I would just pop the compressor housing off like mentioned above and get your calipers out and measure the wheel.
