Cost of a used or rebuilt nissan 300zx engine? v6 3 liter?

[AeFrank]

Im looking into buying a 300zx but it needs a new v6 3 liter engine. I want to see if it is worth it to buy so i was wondering how much a used or rebuilt engine would cost me and where would i need to look? For reference I'm in southern maryland. Thankyou

Many people do not know this but Japans emissions standards are much tighter than ours. They cannot pass after about 40,000 miles nor pass after a rebuild. Many of these are shipped here and sold at a very reasonble price. Check around and you will find these importers and most likely your best price. I have used a lot of these engines and have not had any problems with them.
