Ack! I need to post on this when I have more time.

A) Full Race kits are totally streetable. Nothing more complicated about fueling/octane with them vs any other turbo setup.

B) That stage 1 kit comes with a VERY similar turbocharger as the Drag, RH kits, etc. In fact both the Drag and FR kits come with 57 trims for LS motors last time I checked. There are minor differences, but nothing that would make one streetable and one not.

C) Greddy kits will never be on level playing field as Drag/RH/Peakboost/FR etc. as long as they include that tiny 18g.

D) Its rated to 450hp because thats what that turbo on that motor is capable of generating. The setup surrounding it (including the motor and the EMS) is entirely on your shoulders.

E) If youre building a strip only FWD dragcar, you better be using more than the Stage1 kit! FR kits are great. They are pricey though, but you get good engineering, near flawless fabrication and a well designed kit. That Stage1 kit is designed for street cars.
