hi can anyone help me out im in a bit of a struggle i have a 1994 toyota supra twin turbo and its a jdm right hand drive the only thing that is really getting to me is the cluster which reads out 180 and i was wondering dont twin turbo come with 300 KHMP or 180 Mph and if i plan on chaning the cluster what would i have to do in order to make it run to that cluster readings thanks
