M20 B25 supercharged

[pierism14]

Hello i am new to this forum.
just registered.

i have an E30 325i M20 B25 and i am looking to build a supercharged engine. looking for a centrifugal charger. and i am going to do all the nessesary work so i can run it at 1.2- 1.5 psi.

cant do a turbocharged engine cause of restrictions of the law in my country.

does anyone did any sort of this project?
if yes does anyone know how many hp and torque will the car produce approximently?

thank you
