Thanks.

Overhaul required if engine seized. If timing belt breaks at high rpm. If any bolts give way and cause serious damage internally, if any internal oil seal, bearings worn.
Process you can google. Too long to type.
Estimate cost depends on shops.
Each mechanic has diff opinion on engine building. His mood also affects the result of the engine done. I will suggest you get a car enthusiast to do it. If you have no other recommendation, go consult garage R.

A small little sharing of crankshaft bearing installation only.
*** When installing the crankshaft bearings (mains or rods) be sure everything is absolutely clean. Clean your hands like a operating room surgeon. The only thing allowed on your hands is clean engine oil. The running oil gap is as small as .0005" to .0015" radial clearance. Something as small as a human hair caught behind the bearing shell can make the bearing bind up on crank journal, or it may reduce the running clearance and starve the bearing of oil flow required for cooling, leading to premature bearing failure. Try to avoid touching the ID of the bearing. If you do touch it, add a dab of clean oil and wipe it out with your finger tip. If you feel anything at all there, clean it and start again. ***

Harmony motors probably does that as well. You can get a quote from them in their section. The process may cause quite abit.
