this is an excellent way to spend a whole pile of money and wind up with a bunch of really nice parts that don't work well together what so ever.
think. decide. plan. execute.
it'll be an easier road if you determine what you can compromise on: purpose wise (top speed or light to light performance), performance wise (how many horsepowers do i need), budget wise (need bling, don't need bling), limitations of self (can do this work, cannot do this work) from the start.
