Turbo size

[gsbuick65]

So I'm refreshing this motor, I've heard it had some work done to it. It has forged Pistons arp bolts. It had a small lunati cam. Gonna put a new cam in it. It's supposed to have a bigger turbo but I don't know what size, can you tell without taking it apart?

That compressor is a dinosaur.
Do yourself a favor and buy a new turbo especially with a refresh build.
With the limited info you have put up
64mm billet bb or triple bb will be a ton of fun and spool up like a supercharger.
