hi
looking to swap my 48 A/r to a bigger turbine housing more like a 60 a/r , i'am looking to make around 380 to 400 on a stock gsr motor and I know the amount of exaust going trough my 48 a/r is not gonna cut it is there a way to do it , in other words i want to make my t3/t4oe into a T4 , is that possible
