Regarding to putting a new engine in it:
About 3-4 years ago when I paid a mechanic to do the top end rebuild, I skirt around the option of dropping a low mile engine in it. A neighbor hook me up with a guy he know, and this guy told me it is more cost effective to just sell that car as is. If I insist on replacing the engine, I have to WAIT for a good one shows up that's lowish mileage, i.e. 90k. He wouldn't do any rebuild due to risk of another problem mid way, and he wouldn't charge less than 2k.
My other friend who track his car told me, that even if I do get a low mile engine, I should rebuild it first before putting it in, or it might just be trouble down the road.
Recent search around various JDM engine sources say that these non VTEC engines are now "sold out", and were last sold for around 900-1500 (long block) with around 60k miles. Assuming $800 for labor and profit to put it in (mechanics have to take some risk of rework if he pick up a bad engine), it is still more than the car is worth. At least, it is more than the $1k many assume will cost here.
