I looked for pictures and found some identification, but not for these cams. Any help is appreciated. Sorry about the picture quality.

These cams appear to have 3 rings on the raised portion of the cam and one ring each on the end



This set looks similiar to an ITR set, with 2 rings on the raised portion, but does not have any rings on the very end.

if there are no rings they they are either b16 or gsr cams
pre00 itr cams have 1 ring on both cams
00+ itr cams and ctr cams have 2 rings on the intake cam

Thanks, but that doesn't seem to help me with these...

 

first pic are gsr cams

 

Use a caliper and find vtec lobe lift and then multiply by 1.55 and see what you get.

 

The second set lobe height is...

EX: 1.390" x 1.55 = 2.154"

IN: 1.450" x 1.55 = 2.247"

Ah you need to subtract the base circle of 1.160" to arrive at lobe lift.

So you now have:

EX: 0.230 x 1.55 = 0.356" or 9mm
In: 0.290 x 1.55 = 0.450 or 11.4mm

Hopes this helps you out sir.

I forgot the base circle...
Any idea what the second set is?
Thankyou for the help rocket.

 

Ex. Seems to be GSR.

Correction... second set intake is 1.404" - 1.160" = .244 x 1.55 = .378" or 9.6mm

Would the base circle measurement be the same for a regrind?

 

Nope.

You can measure the base circle with your caliper. It's going to be the min measurement.

 

Thank you very much for the information.

 

Very coo!

Glad to see you have a caliper. Most handy thing in my tool box.

 

good info

 

i just picked up a set of cams today that are the exact same ones in your 1st picture. So is rocket correct with stating that these r GSR cams?

 

they r GSR cams
