Questions about 101200

[mitsumissile]

I just bought a set of comp cams 101200. Do I need to drill and tap to fit them in my 97 GST? Or just drop them in? Thanks

They are drop in cams. Why would you need to drill and tap?

 

[mitsumissile]

Because I heard someone said you need drill and tap for HKS cams on 97 gst.

 

[95blackGsTurbo]

Nope. 95-99 are all the exact same and don't need to drill and tap anything. Take the timing belt off, valve cover off, cam caps, drop in new one's and put it back together. Still doesn't answer my question. What were you told you need to tap?

Please check HKS cams section. I just wonder if comp cams need to do it or not. Thanks

Correct. They've already been pre-tapped for the 97-99 CAS.
