No, our motors spin in the opposite direction and the timing sensor in the Evo 8 is on the exhaust cam.

I'm only talking about cam gears, not cams.

The engines don't spin opposite directions, they are just mounted opposite. And the CAS has nothing to do with cam gear selection since it's driven by the opposite end of the cam. The only exceptions are the 95/96 DSM which uses a trigger plate mounted to the intake cam gear itself and the Evo 9 which has MIVEC.

HKS cam gears are simply labeled "4g63" since they are interchangeable between DSM/Evo. They have 2 sets of timing marks so they can be used on either engine. Take a look for yourself. You can see the Evo timing mark which is straight up from the Dowel pin, and the DSM mark which is 90* from the Evo mark.

Holy brain farts. I completely misread. Excuse my post.

I just looked on the AEM website and the Evo cam gears have a different part number than the Eclipse. Maybe it's just to a unique identifier to distinguish the application.

I also took a look at the HKS gears and Wes is right. There will be no problem running an evo cam gear on your gst. Here is a thread with more details:

They do have seperate locating pims on evos to our dsm's, it can be drilled to fit our engine but might not have the marks for timing though. Other then that all cam gears from.a 4g63 are pretty much interchangeable

Ok, thank you very much.
So as I thought they are all interchangeable, and if not, you only have to make new timming marks.
I'm going to buy and try these set of HKS gears
