There is one nut and 4 bolts. You then need to lift the engine enough to slip the mount out and install the new one. Passenger side is pretty easy, drivers side is a little more difficult due to the placement of the injector pump but it is doable. I have used a trolley jack and a length of 4x2 under the very edge of the sump where the bolts hold it on. An engine crane would make it easier. Take note the front of the car will lift quite a bit until you take the weight of the engine.
Also be careful not to hoist or jack the engine to far.
