This kit retails for $6500 to $7500ish if you bought it new.
I got the kit with a package purchase so I figured Id pass on the discount as I will not be installing it on my vehicle. The design was started but they didn't get very far. Originally design started for an LS motor but clearly they didn't get very far. Comes with unopened bags of couplers, boost controllers, waste gates/blow offs, oil pumps, hoses, piping, electrical harnesses and relays, literally EVERYTHING you need minus one 90 degree coupler i believe.
