Pulley Sizes From Different Motors Question.
Hello, Everyone. I am currently running a b18b with a jackson racing supercharger. I am about to change up my pulley setup. I know that a bigger crank pulley equals more boost because for everyone on rotation it'll spin the supercharger pulley more. But i actually want to install a smaller crank pulley and a smaller supercharger pulley. I currently would like to put on the pulley from the civic type r. Now i was wondering if this is equivalent to the same size as the us type r pulley because I also plan on making the supercharger pulley smaller. I believe the integra type r had the smallest crank pulley size in the U.S. But is this the same size as the crank pulley above. If so then I plan on putting on a smaller supercharger pulley. If you use a 3.2" pulley on the supercharger it will yield 7psi and if u use a 3.0" pulley it will yield 9psi. This is under the assumption that the ctr pulley is the same as the itr pulley. Sof if anyone has any measurements of pulley size it would be much aprreciated. Thank You for your help.

I figured out the ctr crank is 128.7mm
the itr crank is 140.87.
so what size upper pulley should i run to run about 10 psi boost i think i should run about 2.8" upper.
the itr crank is 140.87.
