looking to get these cams installed in 2 weeks. The specs on the side of the box are:

6004272 Intake 10.80mm 107 CL

6005272 Exhaust 10.30mm 113 CL

I posted this on GSC forum as well. Why do I have a feeling these are not S1's? I got them new from a member on the board. If they are not I'll try to sell these then.

 

those are not GSC part numbers, and the lift isn't correct for S1's on the Evo 8, they both should be 10.5mm. The CL matches S1 specs though.

 

i just got a set from evostore, which by the way was a hassel in itself..

it says gsc powerdivision on the box and-

GSC 6002
Evo 4-8 264 10.8mm 107CL

GSC 6003
Evo 4-8 264 10.2mm 113CL



hope that helps

 

and now that you made me question it i just checked GSC's website and their specs are as follows...

S1 Specs gsc-6008S1
Intake 268 Duration 10.50mm peak lift, 107 degree Centerline
Exhaust 268 Duration 10.50mm Peak Lift, 113 degree Centerline.

so does that mean evostore screwed me? im calling them tomorrow and i guess ill call GSC tomorrow maybe i can send them pics and they can confirm if the camshafts are theirs or if i got screwed

either way thanks for making me check silvaevo otherwise i would have put them in my car with out question.

 

i think the early gsc s1 cams were made at the lower duration, then they changed them slightly....look through the gsc forum to find a clearer answer/description
