So I have a 2011 sti and I am just wondering if the stock turbo off a fa20dit would be a direct bolt on to the ej257 I have in mine I work at an independent shop and there is a fa20dit just laying around from an old job, it has everything still with it I guess if I kept the turbo off of it just in case mine took a crap could I use the garrett MGT2259S instead of buying a vf48
