I se that some B16 cams have 10 deg more intake duration and .1 mm more lift. Is that small difference worth anything at all? Or should I just spend my money on muffler bearings? 
Seriously though, I could grab an intake cam for $25.
all gsr cams have the same specifications.
My understanding, and this is from my foggy memory and may be incorrect, so if someone knows better please chime in, is that b17 cams are the same as 1st gen b16a cams. 94+ jdm b16s have slightly different cams and slightly higher compression (10.4:1 vs 10.2:1) plus reworked intake and exhaust manifolds. All of that stuff together accounts for the 10hp bump. I’m not sure if USDM b16 cams are the same as the JDM counterparts. Bottom line is that cam swap alone may net you 2 to 3 horsepower. Probably not worth spinning all those bolts.
Bolts are already spun, head is in the shop. B16 intake is superior to B17?
the b17’s are slightly more agressive. there has been a discussion about it in the past. i think there was a link to “team ef squad” or “team ff squad” that gave you detailed cam profiles and ID methods… look around here or google ssearch. you should be able to find it.
If it is a 1st gen JDM B16 cam (or USDM B16), they are the same.
If it is a 2nd gen JDM B16 cam, it is superior to the B17 cam.
in what way, are they superior? do u mean power wise? if so, in a non forced induced state, one would be lucky to make 2whp & 1wtq after the cam
swap…and thats after tuning. taking ur girl out for the night is a much wiser/promising investment
More lift.

I agree. But if the OP’s head is already disassembled like he said, might as well put in a better camshaft, ya know?

to be honest, years back a few friends and i searched long and hard for these b16 intake cams with more lift. we compiled many cams, 1st gen 5spd & auto, 2nd gen 5spd & auto (both jdm) and we only found 2 things from it…auto b16 cams are the smallest, and all 5spd b16 cams spec’d out the same. the 2nd gen b16 has .2 higher c.r., a slightly refined im, bigger t/b (60mm vs. 58m) so i’m forced to believe this is how they obtained the additional 10hp. i feel u when u say he might aswell add better cams if the head is off. if those cams really do exist though, i would not in anyway consider them superior. itr/ctr cams, yes…b16 auto vs. 5spd, swap them out…the change is noticeable. but swap in these mystery cams for what 2hp??? i honestly believe is an exercise in futility. i advise that the add a set of itr’s w/vt, if he wants an actual increase in power. especially if the cams are being degree’d, and the adding the safety (slightly larger rpm window) of the dual springs on both sides . all in all, a set of itrs and vt can be found for $300-400
well it just happens I have a db2 sitting in my garage. want me to find out the specs? :rockon:
Yeah, If you have a second gen. JDM b16, let us know.
Here’s what I have.
