Well you need to search the forum for sure. But if you do that you will see that everybody agrees
this is an excellent turbo kit. You might need just a couple of screws from your Genesis 2.0T though. I also recommend copying over your turbo ECU tune from your Genesis instead of paying a grand to a tuner. You only need to plug a flash drive on your Genesis head unit and press the on/off button 20 times in 3 seconds. To make the copy, repeat the same procedure on your brz, after turbo installation of course. Since you have the Genesis, why not? I can't wait to see your dyno results, it is gonna be awesome!
