The point of this manual is putting a H22A4 engine from a 2001 Prelude instead of the H23A1 engine in a 1992 Prelude Si. Before you start please think twice because it is a long time procedure requiring garage lots of special tools and experience.

Here are some pictures of the new engine. As you can see it came with all add-ons like power steering pump and reservoir, intake and outtake manifolds, hoses' cuts etc.

First remove the hood to have more space to work and unplug the battery. Now raise the car and remove both front wheels. If you have access to a hoist you are lucky, if not a pair of jack stands could probably do. Then remove the brakes (but don't unplug the hoses or you'll need to bleed them) and attach them with some wire or something to the coil springs.

Now remove the hub nuts, if you got a big 3/4" ratchet or breaker bar it shouldn't be a problem, otherwise just use a 1/2" breaker bar with an extension (metal pipe) it shouldn't be too hard, just put 2 wheels nut to protect the thread and put a pry bar in between and have someone hold it to the ground so it can stop the wheel from rotating. Don't forget to bend the locking tab out on the hub nut before you try to remove it though.

Now is a good time to drain engine and transmission oil, coolant, power steering and clutch fluids.

Now loosen the lower ball joint nut, this one is hard to get loosen. Then you'll need to separate the lower arm from the ball joint with a puller. Then remove the bolt attaching the damper fork to the lower arm. Lift the hub/disk out of the way and remove the drive shaft by prying them out. Do not pull on the shaft cause you'll separate the CV joint. After you removed the drive shaft, put the lower arm bolt and lower ball joint nut back in place so you don't loose them.
