View Full Version : Telling the difference between S13 and S14 KA Cams

10-20-2003, 08:09 PM
I went to a U-Pull yard and snagged two pairs of cams out of 91 240's. I also snagged two extra exhaust cams out of two other 92 240's. Problem is one set of cams has opposite color marks then the rest and has letters engraved on them. I am wondering if someone swapped in a set of S14 cams before the car went to the big yard in the sky. Is there anyway to clearly tell them apart? The markings by the way are Intake- green paint stripe and letters AKR, Exhaust - orange stripe and letters AJW. The letters are stamped into the tall ridge that would sit right behind the first cam tower.

After using a somewhat basic method of imprinting the cam lob onto a piece of cardboard and comparing it to the other cam, they all seem to be the same. I don't know if I would be able to see the difference though. Any ideas of how I could tell if these are in fact S13 or S14 cams?

Anyone have any ideas?

My S13's cam's were green intake, orange exhaust. S14 cams were orange intake, green exhaust. That's about the only info I can offer.

It's brown. Not green for exhaust.

The S13 exhaust cams are pink. (but my memory is super foggy, someone needs to verify the color.)

I'm looking at pictures of both S13 and S14 right now. The colors are defenitely orange and green.

Yeah I seem to remember orange on the intake cam and greenish on the exhaust cam.
It's been a couple months since I've had my valve cover off though http://forums.freshalloy.com/images/graemlins/smirk.gif

Hey, they're not necessarily all the same! Some S13's may have different colored cams than other S13's, etc.

If you have S13 and S14 cams side by side, it's pretty easy to visually tell the difference between the two -- the S13 cams have a broader lobe, the S14 cam lobe is noticeably narrower.

My S14 cams were yellow, but that's only because I urinated on them profusely after removing them, and then quickly sold them on Ebay for $45 before they became stagnant. The S13 cams had the green/orange marks, but I don't recall which one was which, the S14 marks were opposite the S13.
