Every car is different and there are a lot of variables that come into play on what pulley you can run.
im going to do the xp hot cam from zzp and maybe 1.6 rockers.
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.
