I currently run 5.5psi using the Greddy SOHC Turbo kit with the blue box in my 97 Civic. I've heard that with this low boost level, an intercooler is not needed. However, if a FMIC is installed, would this increase torque/HP or maybe help the turbo spool up quicker? What advantages would I gain from installing a FMIC with just 5.5psi and the blue box as my fuel/computer setup?

 

Anything that will drop temps will help power and efficiency. I would get one.

 

Its definately not going to help you spool up faster. If anything it will do the opposite. If you're taking your wastegate pressure source off of the compressor of the turbo you wont see as much boost to the manifold as with no IC. If its not going off of the manifold already you might want to move it there during the FMIC install.
