How do I know what size turbo I need?
The calculation is simple: Divide the absolute outlet pressure that you think you want (14.7 + boost pressure) by the absolute inlet pressure that the Earth says you can have (14.7) and you’ve got your pressure ratio.
How do I know my turbo size?
A turbocharger’s A/R (aspect ratio) typically is the number that is cast into an exhaust-turbine housing that identifies the size of the housing, from the inlet to the radius from the center of the turbine wheel. Basically, the larger the number, the bigger the housing.

2) Undersized turbine housing (too small A/R) will give more immediate boost response, to the point of jumpy boost response at throttle tip-in. 3) Oversized compressor wheel and undersized A/R will tend to exacerbate the compressor surge by making it come up on boost quicker. Surge can damage bearings.
