    yeah i have the same car, you can get a turbo inlet pipe, a lower intercooler pipe. and you can also get a new intercooler but they dont do much help but new inlet and lower intercooler pipe will give you about 15 horse power. because it gives about 25% increase on air flow. and a boost controller will help alot

    The simple answer is yes. However it is not feasible as the entire system is engineered as a unit and upgrading only one part of it will not really work properly. The piping and intercooler are rated at a certain flow rate and if you introduce a turbo with a higher flow the pipes and intercooler will act as a restriction and negate the turbo increase.

    yes BUT there will always be more restriction with stock parts if you change the turbo change the EXT.system and the intake system more air in and out = more power
