What engines could be swapped with 1999 Pontiac Grand Am for more speed and AWD? READ DETAILS BEFORE ANSWERING?

i'm looking to do an engine swap to gain more horsepower/speed. i'm a bit new with doing work on cars, tuning cars, and a bit of racing cars. i'm looking to take my all stock 1999 Pontiac Grand Am se and put a stronger/faster engine in it. my thoughts are for something where i could switch to AWD. the Subaru Impreza WRX STI engine and transmission comes to mind first for me. i'm looking to drag or street race my car. any ideas/recommendations/advice/etc.for a high top speed/acceleration would be greatly appreciated. i know Grand Am's aren't exactly a "top dog" in the racing/tuning world, but i'm looking for mine to set a new standard with mine. OTHER NOTES/IDEAS: i have removed my backseats as a start towards reducing weight. swap out exhaust with a 1999 Grand Am GT for the 4 pipes instead of 2. add a Flowmaster 80 or Borla(i need to research it more) exhaust kit. then with whatever engine i end up getting to replace my current one, adding a twin turbo/supercharger/turbo(whatever fits). lowering the suspension. new higher performance brakes. I have already been told that i would need a new "chip" (ECU) for the new engine along with new gages to keep up with the new gear.
