I have a t25 turbo sitting in my room, and i looked at the intake of it. It has a 2" intake, whichj will make the intake about 50.8mm. the turbine wheel is as big as the intake. does it mean it is a 50 trim ? also where can i find some compressor maps for it.
also how the hell do i read this map. it's for a t3 turbo with a 50 trim compressor wheel

too much of a newbie to the dark side stuff
