i am getting ready to upgrade and wanted to see exactly what mine is now. i know its an older jrnl brng 3" in 2" out and has a precision 63 exhaust hsng. i was told by previous owner it was a pt52. i measured the intake side upby the blades and it mic's at 56mm.and it has a stamp that says "RO" and 1_5 or close to that. thanks in advance

It's definitely an older model. The only real way to know for sure, would be to remove the compressor cover and measure the inducer and exducer of the compressor wheel. Also, you might be able to find the engravers pen marks on the comp cover discharge, typically underneath your intercooler hose. Honestly, it could be anything from a TE44 to a PT52.
FWIW, the PT52 compressor wheels' measurements are:

2.320" Inducer
3.000" Exducer

Also, there should be part numbers on the turbine housing that say what it is as well. If it's a PTE turbine housing, you are looking for numbers that start with THB_-_ _ .
