So this is my first serious build for a Honda motor or anything past simple intake and exhaust mods or cosmetic. I have a 12 civic Si with the k24z7 and so far it's only had sk2 carry back and cai installed with coil overs from tein. I'm looking at the end result being boosted with a turbo but for now, intake manifold swap and throttle body. Exhaust manifold will go when I get the turbo supported and decide on internals. For now, I could really use advice on who had it in the hp/tq department. Real numbers. Rbc, skunk 2 ultra .
