pull the engine and all the parts you want off of it. Then call a junkyard or someone to crush it. If you dont' know what your doing or how to really go about it i wouldn't try to put the engine back together without the right tools and stuff.
Not saying don't do it, but if your not mechanically experienced i wouldn't put an engine back together without some automotive courses or working at a shop for a while. There's alot more to how its built than simply bolting it back together. Torque specs, and preload and everything.
