Well, just to put it in perspective.

A 3L engine bone stock with just a cheap, properly sized t3/4 turbo, basic intercooler, and the stock ~6 pound spring in the wastegate will allow you to throw down 300 wheel horsepower basically any time and anywhwhere! This is on the crappiest gas you can find too.

That T28 will be huffing out 14 pounds of boost on race gas with ice in the intercooler tank to make over 300 wheel horsepower....and ball bearing T28 cost a bunch more too!
Hell, just putting a bigger turbo on the 2.5L can do the same thing but you'd need about 9-10psi in order to do it.

The thing I've been saying for years now is to make a plan with proper goals. Then use the most direct and cost effective plan to get your goal. Ideally do it in stages if money or time is an issue so that you can actually get some usage out of the car after each mod you do. You'll be able to iron out bugs in the setup easier and be more satisfying.............rather than just pulling an SVTProdigy and going for the Gold on your first time through, and not even placing in the finish.
