With only the most basic of supporting mods I suggest no smaller then a 3.5" pulley. You can still run stock heat range plugs, or perhaps one range colder. I don't suggest a 160* thermostat if your in a cold weather area. And you will need the tune adjusted for a 160.
If you need a canned tune, I can help you with that. $125. But you will need to ship me your PCM and I will do what ever tuning you need and ship it back. Doing it this way ensures you have the correct VIN and OS on the PCM, although Intense is very good at using the correct PCM. You will also no need a CASE learn or a security relearn. You can PM me if you wish.
