Rep Power: 725

I need an engine for my car since mine blew up the day before yesterday. Im still establishing a budget. But Im going to have around a grand to spend to put it in, maybe $1500. Im just trying to figure out whats out there that might work for me. My car is an 89 and had the original 290+kms SOHC in it. Im not interested in putting another SOHC into though, so Im looking for a KA24DE or a KA-t I guess unless someone has an SR they want to get rid of real bad... I need the motor by the weekend...
