90 Hatchback DX

Well old memeber in a new place with a new car..well not so new but, my first car was a 90 lx 4dr and all the problems I had with that I could handle but with this car, its a pain in the arse (dont know if you can swear still or not)
The problems I have with my current car is multiple things, a long list. First off the cooling fan doesnt work, and i cant figure out how to run the fan with a toggle switch that i purchased. Also the car seems very sluggish, little to no acceleration from stop to go, i put in new plugs and new accel wires and boots.
I am also burning oil..alot and it seems like when im in 2nd or 3rd in higher rpms, the tach jumps, and so does the engine, i did most of the tune up myself when i bought it, oil, coolant,spark and wires,fuel injector cleaner.
Now my question is what would be easier, fix all the problems that I have right now or look for a low mileage engine that i can do an engine swap with.
Also anyone in the Hawaii, Oahu island let me know.

it would honestly be cheaper to hunt down a hodna motor and do a swap becuase rebuilding a motor is alittle costly and if oy ucan do it yoruself then why bother.
