Re: How far?
Your poor pick-up question: Do you mean it doesn't rev-up quickly? for that you need to have a lightened fly-wheel and follow the steps below.
Remember to upgrade your suspension and brakes as much as you upgrade your engine - your car must be able to handle the extra power.
You can go all out. It is totally up to your budget how much effort you are willing to put in it and how reliable you'd like to keep it.
Start by managing your air intake and exhaust (that is a given change) you can go as far as porting your inlet and exhaust manifolds and cylinder heads.
Then choose if you want to go for new camshafts (high degree overlap).
Remap your ECU (fuel management) or even get a new chip (with custom map).
Going the forced induction (Supercharger / turbo) can be a huge undertaking, depending how much you want to boost. I've heard of guys running (a very modest 0.4bar boost) with standard internals. If you want to boost higher go for lower compression pistons, stronger con rods and you'll need other injectors (or an extra one). Remember you have to allow for an inter cooler, (usually in front of the lower part of your radiator).
Good luck and enjoy.
