I was wondering if it was possible for me to swap my 98 corolla engine with a celica engine

I don't know, you might have to do some research on that. You need to make sure that the engine will fit in the corolla and that it has all the right things (can't remember what they are called). But I would definitely ask a professional.

I agree with dreamer. I would def. ask a mechanic to see if it can be done.
