hey will a 2000-2005 gt celica Engine fit and work in my 96 celica st. my 96 celica engine is burning oil bad and i what some more pick up out of my celica.

its always possible but to spend money on a motor you won't see a significant difference is pointless, especially figuring out how to get it done right. just spend for a newer st motor like a 1999 one if you really want that same motor its cheaper than the 2000 model engine. or since you are willing to put a newer motor, you might as well do a 4ag swap.
