I am trying to figure out whether my R32 GTR has upgraded cams. The cans have a big "T" punched on the intake cam. NE1 know whether this is the stock cam?

does it run lumpy on idle?

 

[peisden]

Nope,
Idle is fairly stable.

normally a sign of cams is they run a bit lumpy on idle depending on cam spec but normally u can notice the difference

Mines got different cams and u can here the difference also it idles slightly higher to help it run smoother.

NE1 ever see aftermarket cams with Aa big "T" on them? The T is surrounded by a circle. Please help me out as I don't want to buy aftermarket cams if these are already upgraded. What are the markings on the stock cams????

 

[T.F.S.]

no T on mine...

Have you tried measuring them with a set of vernier calipers?

Have you tried measuring them with a set of vernier calipers?

Is that a process thats easy to explain in a post? I also have a set of used aftermarket cams (dur/lift unknown) that have no markings on them, but comparing them next to a stock pair, they are obviously larger (on the lift anyways)

Please advise :bowdown1:

rb26zcar, do you have acess to the stock cams? do these have any markings on them?

I have these camshafts fitted to my GTR give a lumpy tickover, marked T then N1. I would think a Tomei cam with the heel ground down on a high lift blank. I have had HKS 260 cams 9.2 lift both inlet and Exhaust but they gave less torque.These may give the Max lift without piston Mods?

thanks Paul,
Thats what I also have on the cams a big T followed by an "N1". Can you confirm these are tomei cams? do you have any info on the specs of these?

I am still not 100% sure of the make or the spec.Not standard though.My car is running the HKS 2530 turbos a good match for these. Adjust your tickover to 800 RPM the engine should be quite lumpy then.
