Lots of questions but this is my next mod I think so if you can help answer these my checkbook will be opening up .

How difficult is it to swap the low pulley? (Should I plan in going from the bottom and dropping the pan to get there from the top)
Do I need a new belt and if so what size?
The dreaded...do I need a tune or can I run it with 93Octane or 93 w/ Torq and no tune?
Will is negative effect the "daily driver" aspect of the car or "just make great..greater"?

Thanks and I am waiting like everyone else to know when and where to order once I get some answers.
