Stillen SC preparations

Nismo6972

I like the Stillen set up, and may do the pulley also, along with the upgraded connections for the SC. I don't want crappy looking piping showing. probably get the covers too. My cooler is Stillen 19 row.....is that adequate?
How much gain you get from the SC? Torque/HP? At what psi? 7-10?
You will need a clutch....if you plan on stretching her legs....CSC is a must too, as the Nismo stock one fails a lot. Issues bleeding the new one, so be careful, and a new Master is recommended too. The noise the HD clutch makes wasn't expected. (Throw-out bearing), but I'm used to it now, as it is only heard outside the car, or with windows down.
