Upgrading head unit?

What would it take to upgrade to a p1 or d1 from a current P600B kit?

I have some interest in this kit in another forum and don't want to bs the guy.

Also anyone know what new 24cc dished SRP pistons are going for?

The blower, bracket, blower pulley, and belt are different. You could also then remove the oil lines, as the P1SC/D1SC headunits are self contained. :)

I did p600b to D1 on a 383 M6 97ss. I purchased a new head unit (ati D1) and bracket with 7.6/ 3.4" 12 rib pulley set. Did all my own hard pipe and a Spearco IC. Eliminated all that rubber ducting. Sold the p600b unit. B.
