GReddy FMIC ?'s

Summer's here and really killing my engine's power -- 1997 Honda Civic EX. I'm planning on getting a GReddy FMIC, but I don't know which one would be good enough for me. With the addition of a dual-stage EBC, I only plan on running 5 psi for daily driving and occassionally bumping it up to 7 or 8 psi when needed. I'd love to get the big Type 24 but heard you have to cut the front bumper support (and it's also a little pricey for me). My other choice is the slighly shorter Type 31; would the Type 31 be sufficient enough for my needs? Thanks!
