I bought the car with this cams, I'm gonna install a green hta and I would like to know if there good enough. I removed the valve cover in search for marks. They have dark orange paint and some marks.

Here some pics.

only first pic is working

 

Something must be wrong on your end, I see all three. But don't have a clue as to what cams they could be.

 

Pull one of the cam caps nearest the cam gear.

 

the "KG" and "ES 4604" are the identical markings that are on my early version GSC S1 non-mivec. That could only mean that the cams are made from the same blanks which are sold to several aftermarket cam companies. My GSC S1's also have the same brown marks, 3 on the exh, 2 on the intake. Best bet is to ask GSC directly to confirm.

FYI specs on the early (pre 2008) GSC S1's are 10.98/10.2 268/266

 

Thanks guys, now I have a clue, I would contact them.

JohnBradley: What I should look for when removing the cap?

 

There's another set of numbers under there that might help you identify them. I think they're "batch" numbers.

 

It will be under the cam seal so you will have to wiggle it a little bit.

PPA is S1
PPB is S2
PPC is S3

...if they are GSC cams

 

Ok thanks guys!
