How much does it cost to rebuild a motor. The shop rate can vary greatly from as little as 90 per hour to over 150 per hour. Most engines will cost between 3000 and 7500 to buy. However that figure does not yet include labor costs.
A 90 01 fwd gm v6 3100 3400 can cost you around 3050 on the lower end and up to 3700 on the higher end. So using a low end shop rate of 110 and a high of 150 the labor on a typical engine replacement can run anywhere from 1100 to 1800. It will also depend on whether you prefer a new or used engine.
On average for a rebuilt engine with a warranty the price is going to be anywhere from 500 if your current engine can be worked on to as much as 3500 or more for a complete swap. See 100 easy car repairs you can do yourself in your garage.
