Just wondering how difficult it may be to swap the 1.8L DOHC with an Auto for the same 1.8L DOHC with a 5 speed?

will the engine and tranny slip right in or is there any special pieces i would need - i.e. ECU or engine & tranny mounts, clutch pedal and 5speed linkage etc?

I am asking because once the engine goes (hopefully no time soon - but it has 330K original) i plan on keeping the car and dropping in a new engine with a 5 speed.
