I saw honda motors has the CTR intake only camshaft for 240 shipped. I've read that its a good upgrade and i'm about to change my cam seals. I've heard the exhaust side on my b16 is basically the same any info advice? Does this require valvetrain upgrades? Is this good for 7-10 hp? I have I/H/E and skunk2 intake manifold in a gen 1 b16? I'm not sure what ECU I have but what would be a decent upgrade without the dyno time.
