I have the floor jack and a suitable piece of wood but was wondering about what i need to disconnect first and placement. I ask because some tutorials say you don't have to disconnect much while others mention much more. Thanks!

What year is your mini? Look at the pelican parts website they have a good write up on putting a pulley on. It is the same process to replace the upper mount. When I did mine I only loosend the trans mount mount and let the motor pivot on it just one less thing to try and line up later. I also put the jack towards the passanger side of the motor. Just make sure you dont pinch the coil pack when jacking up. take it slow and dont force anything.

I have an r53 2005. I will check the pelican tutorial. Thanks! !

The only "special" tool was a reverse torx socket #11 i think for the bottom bolt on the upper motor mount you have to get it from underneath.
