Yea bluebird is almost a plug and play instalation with a JWT computer. The main thing is that the NXen are prone to overheating. With the added heat of a turbo you are really putting lots of strain on the cooling system. The top mount interheater will probaly end up frying eggs, lol nx=egg
. But anyway. The GTi-R is a little harder but not much mainly because of the different turbo manifold and turbo. Not really worth double the price for only like 30 or what ever it is more hp. The other option is to turbo your stock engine if its in good shape. You can go FMAX and tune from little over 200 hp to 400+ depending on kit and level of tuneing. Or get the manifold turbo and stuff from a bluebird, from someone that is upgradeing or something like that. You will get about 170 to the wheels with the stock exhaust, around 200 with a good exhaust on it. Its all a matter of personal tastes and wants.
