According to the info I have gathered from reading all of the threads, here is the deal.

The CSC kit will come in 2 or more stages.

The first stage will be about ~$3200 or so and will include all mounting brackets and the CSC itself (a Paxton Novi 1000).

A stage 2 will be released later, that will include an intercooler as well, but you will have to replace your fuel pump and injectors and possibly tranny before you are able to do this mod safely.

All of that info, I have pieced together from what Matt M (of IPS - the company that is making the kit) and Zooomer (of ZZP, the company that is going to be selling the kit) have either told me personally or posted on public forums.

FWIW :p
