Every car is different and there are a lot of variables that come into play on what pulley you can run.

Oh so just roller rockers, not a higher ratio, that will work fine. I just assumed when you said rockers you were talking about a higher ratio. Thats a good choice for a cam too, very good cam, you won't be dissapointed.

So let me get this right, XP cam, PEM'*, 2.5" exhaust, 180 tstat, and intake. With that setup I would say a 3.2 or 3.25" pulley should be okay. Scan to make sure but I'd say you should easily be able to run a 3.25 pulley.

yeah you should be ok with a 3.25.

I have a similar setup on one of my GTPs. I see almost NO KR with the S1X cam/3.25/CAI/custom exhaust.

Honestly I was running the XP last summer and granted its a nice cam, but if you dont know how to tune your car, you will be A LOT better off with either a ZZP VS cam or Intense S1X.

I've never had any problem tuning with it. It actually seems easier to tune to me than the stock cam, but it all varies from car to car and whatnot.
