Turbo Identifaction

[Adz2332]

Im about to get installed a power fc and boost controller etc etc.

When i bought the car the seller claimed he had some N1 turbos installed, the type with steel wheels.

So i would like to ID them to know what sort of PSI i can run through them. I was told i MIGHT be able to see a seriel number from looking from the top. pic attached of where i was looking but all i could see was GARRETT.

Any ideas how i could see better? or if i took something off. or from underneath??

cheers
