KJ would be the person to talk to about it, but there's much more involved than you seem to understand. You have to cut out the firewall for one. . .

The h22a motor does not fit right into a crx without basically cutting the firewall out around the intake manifold and rebuilding another in its place that makes room for the motor to sit back as far as possible so the axles will sit inside the front forks. All the mounts would need to be custom made along with some sort of custom hybrid axles or custom axles altogether. For me I wouldn't even worry about the weight issue that much but I would worry about the axle angles. Basically if you are not going to do this yourself you are going to pay alot for someone to do it. And if you do do it yourself you need to be a good fabricator or you will waste alot of time.
Here, now try running a search next time. . .
