L28 engine? Everyone has there own recipes, but.......
$2k isn't going to buy you a lot of parts and labour, so you might consider:
ringing Ted Stanwood of engnbldr.com for some 1.73"/1.49" valves;
higher rate springs;
port and reseat the head;
a new G2 spec cam grind ; for student use I'd suggest a 70°in/72°ex 8.25mm lift spec; #1
adjustable cam sprocket;
triple DCOE 45 sidedraught webers, with 40mm chokes;
try to pipe an intake manifold to the front of the car if you can.
extractors (e.g. 24" valve to collector primaries).
If you can be guaranteed a supply of decent octane fuel, you might consider raising the compression and bores sizes.
This should give you an engine approaching rally spec, and a pretty cool sounding unit.
Putting a turbo on can be a bit daunting and will require suitable carbies. The cam should probably be kept around 62°. Don't port it too much as it will tend to flatten out the torque curve and not give you that peaky power boy racers desire. For street I'd keep the exhaust side AR to around the 50's or 60's for low end torque, rather than going for high end. If you want to go turbo seriously consider a turbo engine or fuel injecting it and fitting an aftermarket ECU.
#1 there are several works cams ranging from 68° to 76°. Obviously the bigger advertised duration (e.g. 4 x 76° = 304°) the more lopey, less vacuum and more fuel is used.
