When you build a high horsepower honda engine most people use the OEM set up utilizing an intake cam from an ITR(Some use CTR's but the part #.'s ar he same so ) and an Exhaust from a CTR. SOme even gt toda, spoon, skunk2 cams to make more power. For some of us that have b16a heads, we have become attached to the etremley noticable "baaaaahhhhh" of he Si/Sir cams. My question to anyone is which cams make the power and stil emit the "baaaaaaaahhh". In the future i plan to build an LS/VTEC and build the SIR head with ITR parts (retainers, dual vave springs, manifold) but i want a cam that makes the power and the sound.... sorry
