my buddy gave me a schwitzer turbo off a mack engine. the turbo spins good with little shaft play but i took it apart and the comp and exhaust wheels are both eat up some. curious as to the specs on this turbo and if it would work good in a twin setup. i measure across the comp wheel on the smalliest part and it measure like 2.5 inches but the housing is huge. my stock h1c wheel measured like 2.25 inches. dont seem like much bigger to me

 

What are the numbers on the tag? i the mack schwitzer turbos are really hard to find specs for.

 

it doesnt have a tag it has some numbers casted into the exhaust housing but thats bout it. no tag on the comp housing there was also some number scribed onto the back of the comp wheel.

I did the metric conversion on it and a 2.5 inch inducer is like 63.5 mm that's a dencent sized turbo but I'm still unsure of. Exhaust housing size or wither it's even worth rebuilding or if I can get parts
