i have a 94 honda civic dx body with a 96 b18c DOHC VTEC engine. the engine has approximately 85xxx miles on it. it has an LS transmission with a stage 4 clutch. it has been bored out, aftermarket fuel rail and pressure gauge, cold air intake, intake manifold, exhaust system, and computer. the car has been lowered close to three inches with some aluminum suspension parts. about a week ago a piece of the piston sleeve broke off, fell down into the oil pan and got sucked up into the oil pump. this shard of metal broke a gear in the oil pump and threw of the first bearing.. given the damage done to the engine what would be a rough estimate on what i could sell the car off for to someone looking at it?
