Rb 26 Camshaft Identification

[exXU1]

Have searched and can't find any thing - Some one out there answer this one for me please - Just striping down a used engine for a rebuild. The cams i assume are stock , not sure though as they look a little differant than my previous out of a 93 -R32 gtr, this is out of an 89. No markings on the cam caps ( ex 1 etc) and the cams both have IN or U1 writen on them and that's all , i know HKS etc have IN and EX stamped on them .

Hey they are probably stockers - but not sure ?

Any help appreciated .

The only writting on the whole cam is in or ui up the other way -no dot on top of the i or1?????????///

Surely some one knows about this ?

I have just opened another "stock " RB26 motor and the cams in this engines this say U3 on them, wish someone new how to identify and could let me know if they are stock or not?

Have you compared the lift between the two sets of cams?

well have you compared it too a tomei or hks poncam or just a normal cam? Coz if you haven't maybe that'll be a quicker way of checking instead of sitting there wondering when someone else will do it. Usually tho HKS or Tomei ones should have their logo embedded on the actual cam.

I am not just sitting here waiting for someone else to "do it". Rather i am inquisitive to find out if any body knows.

Of course i could compare to a cam made by other makers -IF I HAD ONE. That's why i am asking if any one has seen ,known of or have any idea what these numbers and digits mean? I am well aware of the names stamped on the cams from HKS etc -as i have said in my first post - there are no other markings on either of the cams??
