I have a 93 civic SOHC VTec 5spd. I was wondering how much power to the ground would I have with the following mods? DC 4-2-1 header, AEM style cold air intake, 12.5lbs ACT Sreet light flywheel, 2.5" custom exhaust with Megan racing muffler, OBX intake manifold, RH racing crank pulley that weighs 6 ounces, vtec head with port & polish skunk2 stage 2 cam, crower springs and titanium retainers. And will I need to upgrade my fuel system and or install a piggy back system?
