What size turbo should i run for between 14-18 psi? I was runnin a t25 till i broke a rod now im rebuilding and decided to go bigger. I also wanted to kno what would be a good FMIC to get its all gotta fit in a 90 crx si with the a6 motor.

 

In order to properly size a turbo, we need to know what motor it is going on, as well as any mods that will effect breathing (airflow) such as cams, headwork, etc. Power goals are helpful too.

Without that information, I would just recommend something like a 50 trim or a 60-1, with a .48 or .63 turbine housing.
