Rep Power: 0

I have a 95 CX. I put a low mileage JDM D15B non-vtec which is apparently the equivalent to a USDM D15B7? Anyhow, I am looking for more power. I have made a straight pipe exhaust, hollow cat, DX intake mani/tb/injector swap, CAI(functional ram air), accel cap/rotor, brand new distributor housing/assembly/new coil etc, colder NGK plugs. It feels really strong but I still have the CX tranny. I want to use an SI or EX trans, how noticeable will the power feel then and what all do I need in order to do the swap? yes my car is already a 5 speed.
