What is a 50 trim?

[Slider925]

I am new to this turbo thing and I see alot of posts talking about a 50 trim or 60 trim turbo. Can someone please explain to me what that is and maybe some examples of a 50 trim and 60 trim?

I don't think that you answered his question. The "trim of a turbo is simply a ratio between the size of the inducer and exducer wheels. I forgot the formula, but just for example my " 50 trim" has a 76mm turbine wheel and a 54mm compressor wheel. Any turbo that has the same wheel ratio will also be classified as a 50 trim. But for our purposes here we usually use 50 trim to a refer to a 50 trim turbo containing a specific garret T4 compressor wheel. I am sure that someone could respond with more info if you need it, that is all I can remember off of the top of my head.
