Not saying that your motor isn't worth jack.... just that you don't have the engine building reputation that a shop does so they can command the higher price tag. The second piece is (and this if for everyone building their own engine and wanting to get money back on it later) if you put the same number of new pieces into a rebuild that a engine builder does it will push the cost of your rebuild into that same price range even without considering labor. They are able to keep prices down because they buy parts at shop rates and also in quantity, they also have to buy large numbers of core engines to find the good parts. The profit margin they are making on an engine is not as large as you would think.

You do get what you pay for. I think that the best rebuilt engine write up i ever saw was done by mazdatrix in one of their hard catalogs i don't know if it is on their website but the jist was anyone can build a motor out of a pile of crap that can last 12months (in a street car that is)

As for the value of an engine. I have been severely burned lately by used engines and it is for that reason i don't recommend buying them at all regardless of their pedigree. on the other forum i am listed a BAD GUY because someone bought an engine from my friend (i hooked them up and made the deal happen my involvement) that was supposed to be a low mileage engine it was sold for around 800 in parts and money and it turned out to be bad in less than 30 days after install. Now it was compression tested and it was coolant pressure tested but that doesn't always mean that it is good. When I am buying a used engine I really only look at it as if it is a core... and when i sell a used motor I (me that is I can't speak for my friends obviously) tell the buyer up front that it may last a long time or no time at all. bottom line it is a used motor that we (usually) don't know the whole history on.

What do I think is a good price for a core 200$ no more at this time not willing more and that would be for an unopened motor.

What do I think is a good price for a used motor no more than 800$ and I would have to see it run in a car and preferably under some type of load. Just because it runs doesn't mean it is good. I would suspect the motor to be bad if when I am coming to check it out it has already been warmed up.

What do I think is a good price for a rebuild 1600 is on the low end and although it may be a very good motor i would want to know what went into building it... specifically what parts and who made them.... there are companies out there that make really cheap parts that aren't all that good but they are new and they will last a couple of years.

Also about a rebuild that doesn't include special engines and porting and special prep... these guys are professionals you will get what you pay for but you will also get a warranty as well.
