Wow dude, you dont know too much about Skys do ya? Well you came to the right spot, these people will help you out, and answer every question you have. Anyways, all GTR come with the RB26DETT, HICAS and ATTESSA. RB26DETT stands for Racing Bred 2560cc DOHC ECCS (Electronic concentrate control system) Twin turbochargers. HICAS is HIgh Capacity Active Steering. Its pretty much a sweet ride, but if you dont have the money, just got with an R32 GTS-T, not a GTR by far, but the RB20DET can be boosted up pretty easily. Any more questions post (sorry I didnt go more in depth, I gotta run) peace foo's
