I emailed a guy I know for a turbo asking for a .60/.63 or .48/.60 turbo. He e-mailed me back with Trim sizing which I'm not to sure on,
Can anybody make sense of this, I'm looking for a turbo like the size above to step up from my 14b

His Reply
I Have One That Is Like A .60 Or .63, I Do Not Know How To Mesure Them But This One Has A Big Housing, I Have A .50 Trim One As Well As A .48 Just Let Me Know What You Want Man.

 

the 50 trim he's got is most likely a 48/42

 

yeah 50mm is the inducer on the .42 t3 compressor wheel, 60mm is the .60 compressor wheel inducer size.

 

Well he wants 170 which is a little rich for a guy who says he owns a turbo shop and can't even provide me with an A/R size, and has no clue how to find it out.
