Camshaft Identification?
 

Hi fellow Honda-Tech'ers. im back to nag again.

need some help identifying some camshafts from a B series VTEC motor. i havent measured them as yet as i dont have a vernier on hand. However the markings are very strange. I had them in my B16a6 and i went from making 117kw and 158Nm to 141.6kw and 171Nm. - so they made decent power and i was happy with it. i have done some research and the look similar to "pre OBD B16 cams" as seen in the thread below due to the lack of O-rings.

but then the markings and stamps throw me off. one cam has H01-IN(it looks like, i thought it might be HOL at first) and the other H01-EX. These are on the dizzy side of the camshaft and look almost as if they have been hand etched/engraved onto the surface as seen below.

The exhaust camshaft(H01-EX) has a letter "M" stamped in the middle of the camshaft..

The Intake Cam(H01-IN) has the same letter M stamped on the cam shaft and then on the opposite end of the cam has the number "2" stamped.

been doing some reading and it seems they could possibly be the old skunk2 tuner 1s or OBX cams? not too sure on this myself but was hoping you guys her might be able to help. Ive already checked out FFSQUADs thread as in the other post.

Any ideas peeps?

Bump! anybody?? done a bit more research, focusing on skunk 2 tuner 1's.. found a few more posts here on HT, but still unsure as some say they are genuine s2 from the EARLY days of there lifetime, and some say they are fakes....

Maybe contact Skunk2?

i contacted them the same day i bumped this up. According to them, these are "150% OEM" camshafts, and not skunk2. no im trying to figure out just what OE cams they are by the markings on them.....

FF-squad for OEM cam ID.

hmmm reverts me back to my original suspicion of it being the 89-91 B16a cams. but then that doesn't explain the figures they made..... interesting.

They might have been reground.
