Its appears to be a turbonetics turbo.

I was told it is a t3/t4
on the exhaust housing it the number 20359 meaning its a .82 turbine

The compressor housing looks like an old T04B or T04E, but I can't be sure, there is no number on it. should I pull it apart and take measurements and more pictures?

the reason I am asking is because I need a rebuild kit for it. the blades look fine, but there is quite a bit of shaft play.

any help would be apprecaited.
