Hey Tao, may I ask what your recommendation for my stock internal 1jz would be to replace my twin factory setup, I want to maintain the quickest response while being able to chase 300kw with minor headroom above That for say 350 as when I do some headwork soon I will put studs in it and up the boost a bit more. Have an emanage blue to be installed, and already have an FCD with profec b controller currently on a jzx90 mark 2. Supporting mods there but need to work on the fuel system. Just trying to narrow down a specific model in the lineup
