does the celica 3sgte...

Hi I've been doing some reasearch but I needed to know... Does the celica 3sgte engine fit in the mr2? I mean the regular engine has the same engine code. Reason I asked is that the celica's 3sgte is much much cheaper than the mr2 3sgte.... If it does fit is there modifications involved? like a lot?? since it is a top mounted intercooler......
