Turbo questions
Im still pretty new to turbos but im confused about A/R numbers and trim.
I bought a car and the guy said its a t3/t4 .48 .62 turbo. So my question is the .48 the exhaust turbine of the turbo and the .62 the compressor turbine? Or is .48 the compressor size and the .62 is the compressor turbine?

Re: Turbo questions
.48 is the turbine housing size
.62 is the compressor housing size
there's an article on Garretts site explaining aspect ratios, wheel trim, etc. I'll find it and post it.

Re: Turbo questions
So do you mean the .48 turbine housing is the size of the hole where the turbine sits? And the .62 is the end of the turbo where it connects to the intercooler piping right?

Re: Turbo questions
The inlet (or for compressor housings, the discharge) cross-sectional area divided by the radius from the turbo centerline to the centroid of that area.
