If you already have a 4agze aw11 disregard everything below except for drilling for the new shifter.
First you need the correct bell housing to bolt a supercharger motor to a 4age. You also need the correct clutch/fly wheel assembly as they are different.
You need to have a starter to fit the 4agze flywheel, you also need to make sure your 4age doesnt foul the new starter position (some have external oil drain, however, if its the standard aw11 4age then thats unlikely).
I have never done the conversion on a supercharger box however it is likely you will need to drill a hole and bore it to fit the aw11 shifter and oil seal. You will then need a flange to cover where the old shifter was.
Then its unlikely your standard aw11 shafts will fit in your 4agze gearbox. You will need different shafts.

Can you give us some more details about what your trying to do and the currect spec of the car.
