Now start removing stuff that'll be in your way, battery, air filter, air duck, radiator, etc. You might need to label some hoses you remove so you know where to connect them afterwards. There are 2 smalls hoses coming out of the speed sensor on the 4th generation transmission, it's on the back of the transmission so you can barely see them. If you drained the PS fluid you can remove them without worrying about making a mess. Also don't forget the transmission cables.

Now remove the header down-pipe from the exhaust manifold, there are 3 nuts and they are probably tight so it helps to have a torch to cut them out. Then remove the 2 bolts on the bracket on the header down-pipe behind the engine, you'll have to get them from under the car. And disconnect the O2 sensor while you're there.

Now with an engine hoist attach the engine with chains on the two hooks on near the power steering pump and the other on the transmission. Lift until the chains are stretched and remove the engine mount bolts. Then start lifting the engine slowly to make sure everything is unplugged. A little trick is to put the chain slightly smaller on the driver side so you can lift that end first and get the transmission to pass under the mount. Also once the engine has clear the car, lower it to a few inches off the ground in case something happens it won't fall from too high.

Here are few pictures of the engine and the empty engine bay. If you look carefully in the first picture you can see the two power steering hoses plugged with a hose and bolts where there's a big oil spot.

With both engine on the floor, you will need to swap a few things from one engine to the other. First, the vehicle speed sensor (VSS), as you can see on this picture they are different. The one on the right is the sensor from the H22A4 and the one on the left from the H23A1, notice the 2 hoses coming out of the one on the left. Those hoses are power steering lines they are used for the speed sensitive power steering of the 4th generation, that's what makes the steering stiffer as you get to higher speed. On the 5th generation the power steering works differently, it uses the RPM instead of the speed. Also the gears on the sensors are different length but they have the same number of teeth and they look quite alike when you put both side by side and the sensors fits so theatrically it should work.
