You can turbo your engine. But it depends to what extent for what you will need to do.

I think you can run around 7 or 8psi on the standard engine so you will just need a turbo,manifold for the turbo. A lot of re-wiring and get the fueling sorted. Possibley new injectors.

If you wanted to run more boost than that you would need a low comp rebuild.
