I thought I saw in one picture that someone put the NB block right on the existing copper system?? Could I have seen that right?

So I assume the copper piece over all the areas is one unit and when you take one off you take them all off?

I was hoping to only to do the NB since I know it gets toasty and leave the other copper units there if they where individual parts.

I could use an Enzotech for the SB like I did on my 680i. And just use ram sticks for the mosfet.
