2003 Impreza 2.0 GX engine
 

Im hoping somebody can help me, I have a 2003 Impreza 2.0 GX. The bottom end is rattling! I have removed the engine but I'm struggling to source a replacement 2.0 litre non turbo engine for a 2003 model. I have the chance to buy an engine from a 1999 Impreza sport! Would this be a suitable replacement?

Cheers
