What engine is compatible with my 2003 corolla on 2003 Toyota Corolla
One just like it came with, whatever that is! I think it is about 6 different possibilities counting diesel, you did not post that info.
What other type of car that would have the same oil pump that will fit for my 2003 corolla? It's a 4 cylinder 1.8, from what year to year and make and model
Replace it with a new oil pump that will fit YOUR engine! Might as well replace all timing componets while you are at it. Too much labor involved to have to do it again later!! Never install any used parts on the inside of any engine!! Just asking for trouble if you do. Suggest having it checked out before doing any work, unusual for an oil pump to just go out on this engine. Good luck with it.
