I'd say jus take it to a mech that specializes in turbos, they;d know exactly what to do. And i may be wrong but Im not sure if anyone on here wants to do a job that could potentialy mess up and end up costing u a lot more money than you'd pay someone to do. But yeah, if u kno how to do it right, you and your friend of a friend could go ask some mechanics for advise about the issue and do it yoursef,,will save u a bit of cash for more mods lol ..
good luck
