JAC,

Thanks for your info. Appreciate it.

 

Globe, how much hp each stage will yield depends on the car. BTW if anyone currently has a stock Twin Turbo Supra Toyomoto can give you 350RWHP (est. 445hp) for $1500 installed. They give you a fuel cut defenser, air cleaner, exhaust, downpipe, and a Boost Controller. Almost 450 flywheel hp for $1500, not bad at all.
