i think the 4 banger will do all that u want. if u getting a 6 i would get post 90 so u can get a fuel injected one. if it were me i would go with the 6 just to have a little more power. this way if u decide to put some slightly bigger tires or what not you have more power. i am sure some of the other guys with more experience with the 4's will help out too. and btw where do u live? i like that daily commute i am jelous.
