Hi Chris-w
Just done exactly this only 2 weeks ago. As has already been said, straight swop. The only difference we found was the prop is slightly different, the 325 is slighty shorter (maybe someone will confirm that?). You will need an ecu ( i got one from ebay for £20) and the airflow meter for the 325 (should come with the engine.
Took an 8 hour days worth of work from taking the 320 lump out and have the car running with 325 power, that includes a few tea breaks winkeye ..

If you have done other engine swops, this is a doddle !

Good luck.
