If you want to be real smart about it, you need to decide what if any plans you have for the car. What fuel do you have available in your area? How much money do you plan on investing into your car? Do you already have a tuner? If not, now would be a good time to find a reputable shop and get their advice on your plans.
350whp honestly is not a ton of power so you really won't need the most ballar set-up to make it reliable. I think who does the engine build will play the biggest roll in how long it's going to last.
The only advice I can really give you at this point is don't buy too much turbo if all you're looking for is 350whp. Spend some time in the Proven Power section of the forum and check out other peoples set-ups that are in a similar power range as your goal. Blouch Dom 3 XTR comes to mind if you plan on sticking with stock location. Or check out the latest and greatest from Forced Performance.
