Hi I need some advice.

I have an SXI 1.8 16v, year 2000. The cambelt went, not good.

I bought a second hand engine that had the same engine code as mine. However when it arrived its the 1997 shape, still an ecotec though.

Does anyone know for sure if this engine will fit straight in or if i removed the block ( well not me exactly of course ), will that fit straight in. I was hoping to just change this as i have been told it will save me having to change the engine codes etc etc.

Any help of advise would be much appreciated.
