The mods you buy depend on where you wanna end up. the basic upgrades everyone gets first are Air Filter, Downpipe, Cat-Back exhaust, and Boost Control.
if all you want is to rais the power from 200rwho to 250rwhp, you can go with any kind of setup using these four basic upgrades. The cheapest way to get to this power is a K&N factory drop-in($$30), home-made downpipe with 2 45deg elbows and some welding($$50), cat-back exhaust in 2-1/2" custom bent($$400), and a couple washers for boost control($$1).
if you wanna get to 300rwhp, you need to buy the better choices of those 4 basic upgrades, plus do a few other things. So now, you need to get a K&N filter charger kit($$200), HKS or similiar 2-1/2" - 3" downpipe, 3" hi flow cat-back exhaust($$600), 3" hi-flow cat($$200), and Electronic boost controller like the profec "A"($$700). You will also need to adjust the timing, use light weight oil, new plugs/wires, unorthodox pulley,. etc....
You can run both of these setups at 12psi on the stock turbo, and your reliability will not suffer a bit unless you are a crazy abusive driver.
If you wanna run even more hosepower, you have to start with the better components, then start adding other things like turbo upgrade or replacement, intercooler, bigger injectors, better fuel map system, stand alone fuel system...these items can easily cost $$1000 dollars or more each!
As you add more mods, the increase bang for your buck drops the most cost efficient hosepower can be found back at the basic upgrade level buying the cheaper components.
