In the words of MichaelDelaney, you can get this but what are you working for? This piece works best in conjunction with ITR cams since the manifold is eliminating your secondary runners. At that point you would also need a VAFC or Hondata datalogger to change the VTEC engagement point. A good free flowing exhaust, header, and cat are also vital. At this point you would see a 8-10 hp gain in the higher rpm's from the manifold. Otherwise, maybe 2-3. This package, tuned would put you just sub 180whp. Tuned with my manifold and the above package plus Toda gears, I am pushing 183.5whp and 141.5 wtq
