What's a IDIT core engine worth? I found one on marketplace about 50 miles away, mostly complete minus the turbo, valve covers and flywheel. He says it had 200K miles but was running good when pulled. He's asking $350 for it but it's been listed for over three months so I'm sure he'd take $300 for it. I wouldn't mind having a core to build in case mine ever spills the beans.
