The RSX and Si JRSC produce about the same boost. Its all about Blower Pulley and Crank Pulley combination. If your using the stock k20a2 cp the 3.2'' Blower Pulley will produce about 9-10PSI depending on i/h/e mods.

This might help you. I don't have the break down for a k24 or ep3 crank pulley though.

you can give a general guide but psi will vary with altitude, humidity and exhaust restrictions. but a good reference would look something like this,

bp=blower pulley
a2 cp=crank pulley from 02-04 type s
z1 cp=crank pulley from 05-06 type s

bp l a2 cp l z1 cp
4.0" l 5 PSI l 4 PSI
3.8" l 6 PSI l 5 PSI
3.4" l 7 PSI l 6 PSI
3.2" l 9 PSI l 7 PSI
3.0" l11 PSI l 9 PSI
2.8" l13 PSIl 11 PSI
