What size turbo should I upgrade to?

What is "fuel system"?

Be careful what you wish for...
"Cheap will bite you in the ass."

The stock injectors max out around 240hp.
Even with an upgrade fuel pump, you might get another 15% more.
That doesn't leave you with a safety margin, as the stock turbo can hit those numbers.

Larger fuel injectors require some kinda control if you're still using the stock ECU.
Fuel computers are popular, but they can only do so much.

You understand where this is going?

Unless your engine has been recently rebuilt, it's most likely over 100k miles.
Adding the pressure of more power can cause the engine to kill itself in short time.
Do you know how much a rebuild costs?

I would recommend to get some kinda FMIC, as this increases your safety margin and gives you a nice bump in power (as long as the IC is not too big) doing it "the right way" - dropping intake temps.

If you still insist on getting more power from a larger turbo, compressor upgrades or hybrid turbos are what you're looking for...
