The way it's constructed, you should be able to do almost the entire build without the engine. The only suggestion would be to leave the front turtledeck off until you have the engine. This will allow you to mount the tank and route the throttle cable with proper placement and ease. This will most likely also mean holding off on covering the fuse too.
Here are some photos of my 4 * in it's current state.
