The turbos can be upgraded, by replacing them. For this you need to pull out the engine.
A better exhaust and intake will also increase the turbo performance.
Downpipes can also be added to avoid turbulence on the exit of the exhaust giving it a better spool up time.
Injectors need to be replaced and ECU needs to be remapped to give better fuel needs once you have more air going in. There are different size injectors, 555cc, 615cc, 740cc etc.
Stock turbos (Garret AR .48) are good up to 16 psi. Injectors 370cc are good for up to 15 psi, but the ECU needs to be remapped to avoid detonation.
