Congrats on the getting the blower install underway!
Although you'll miss having all that extra power on your bedroom floor, you'll make up for it in the Stang!
I was quoted $800 locally for my install, but I ended up buying mine from ST Motorsports along with install and tune for a nice package price.
I'd assume it wouldn't be too hard for you to get it installed for less than 1K in So Cal....
Give ST a call and see what they'll charge you.
I think it would cost more to go there than it would to have it installed I live in tampa
