I know I know this has been covered many times before but I have searched. I have a JDM itr that I bought used and cant quit find the exact cam markings. I've searched and looked over the FF-squad forum many of times. On my intake side cam protruding rings don't match, then the exhaust side same thing along with the ends of mine not be beveled like the one on the FF-squad post. There are no markings on the ends of either cam and the only cast letters I see are M 2 on intake and just M on exhaust. So I'm just trying to be 100% on what I have before I get my block rebuilt any help would be appreciated.

Intake cam




exhaust cam

 

Looks like you got gipped for some 92-93 B16 cams which are junk!

 

The car actually made pretty good power when I got it tuned last. It made 199whp with stock bottom end and bolt ons 68mm TB, 440 injectors, fuel pump, rail, regulator, I/H/E, intake mani on s300

 

Also on the 92-93 cams you mentioned I noticed on the exhaust cam there's large gap between the protruding lines and where the actual cam begins which mine don't have.

 

They are '94-98 B18C1 (USDM GSR) camshafts.

 

I looked at the gsr cams I think your right going to grab a vernier caliper this week and measure them.

 

Finally got around to borrowing a digital caliper and these are what measurement I can up with time after time.

Intake 36.85-29.7=7.15. 7.15x1.54=11.0. So 11.0 lift on intake cam

Exhaust 36.5-29.7=6.8. 6.8x1.54=10.4. So 10.4 lift on exhaust cam
