Your first major upgrade would be a t25 turbo, as the stock turbo and manifold is very restrictive and runs out of breath at ~10psi.
Many would say T28 or larger, but if you like the instant boost of the 4efte, then using a smaller turbo like the T25 is a good option.
I can suggest other upgrades but would need to know what you have already.
