I just realised my throttle body for the 323i is MUCH smaller than it's counterpart for the 325i. Could I reasonably expect any power gainby replacing my stock unit with the larger 325i one?

I doubt it.

When did you last check / adjust your ignition timing ? Far more power to be gained by doing this PROPERLY , and it is FREE ! :)
