you will loose power as that's a forced induction inlet.
ways to gain power that are tried and tested and listed on here for N/A Z22SE's are, cams, flowed head, 2.4 inlet, 4 branch exhaust with full system, raised CR, balancer delete, lightened flywheel and bottom end, remapped ecu, bigger valves, ITB's
some will just improve the response and make the engine rev more freely while not gaining power.
but by far the cheapest way £/bhp to gain power is to go supercharged. 100bhp+ for £1500 ish....................................
