for sc's the kits are the best way to go, as a bracket that is not perfect for your car and the compressor will cause the pulley angle to be off and throw belts. the $4400 sounds about right if its the vortech kit. you may be able to find it cheaper elsewhere on the net so look around alot. if your looking for low boost 7-8 psi and it's for the camaro go for one of the tailpipe turbo's, yes they are not that well proven yet but the theory behind them is sound and the dyno numbers are sound.
