I vote keep it original and buy a perormance car lol

If it's clean a 79 BMW is getting to be somewhat of a collectors item

Keep it stock and clean.
Buy an e30/e36 to beat around.

It depends on your budget.

1. add some cams or turbo the original motor
2. M30 3.5 big6 swap
3. above with TCD turbo kit (this should get you moving!)
4. something more nostalgic = S14
5. or swap an M88 or S38

Cams don't usully work well in that motor due to the CIS injection system. And if you don't increase the CR, cams are not going to help a great deal.

The cheapest thing to do is probably find an old Callaway turbo kit for the 320i, or drop in an m60!

The cheapest thing to do would be sell it and go buy an E30

There is lots that can be done in terms of performance, although it depends on what and where you want performance. If your talking hp, then undoubtably the best for the buck would have to be an engine swap of some sort.

How is the condition of the car? (post some pics) If it's far from pristine original condition, then "I" say modify it as much as you want. I love e30's and I still want one, but theirs enough out there. With that said, the saturation of e30 & e36's only makes your e21 standout. Just don't expect to have a screamer unless you have the wallet to build one. An e21 is a fun car with or without a ton of hp, as it has it's own classic charm and quirks.

Modifying a car is not all about hp and I'm not even sure if that's where your focus is. You may have the budget to build a rocket, but theirs a few things that can be done if you are on one. You can definitely make the car run smooth, efficient and quickly with little money involved, but yet have a fun enjoyable ride.

Anyhow, checkout the e21 FAQ section on bimmerforums, theirs a lot of useful information to help you get started or plan your direction. But support yor own and keep active and updated on maxbimmer as well.

Good luck and congrats of the acquisition!
