will a 2.4l 95-00 fit in to my 96 eclipse gs has a 2.0l,

2.0l engine piston or something rather is jumping in my engine. so bought a 2.4l 95-00 i
have both engines next to each other and noticed not that many of my parts are gonna
fit correctly on the 2.4l fromt he 2.0l engine.

the intake manifold i took off my 2.0l and put on the 2.4l engine and the sensor right
next to the intake manifold dont remember what it was cald but the sensor wont fit next
to the intake manifold is it a diffrent sized one.? that will work or do i need to buy each
part for the engine to make this 2.4l engine go in my car,..

also the intake manifold is on the front of my 2.4l engine and on the 2.0l engine it is on
the back will it still fit in my car with them being on oposite sides
