* Condition of the engine: A rebuild of a seized engine will cost significantly more than one that simply needs worn parts replaced. A top-end rebuild (heads, valves, etc.) is much cheaper than a full teardown and rebuild.
* Parts used: Using OEM (Original Equipment Manufacturer) parts will be significantly more expensive than using aftermarket parts. The quality of aftermarket parts also varies greatly.
* Labor costs: Shop rates vary widely by location and mechanic experience. A highly specialized shop will be far more expensive than a local independent mechanic.
* Scope of the rebuild: A simple rebuild might just involve replacing rings, bearings, and gaskets. A complete rebuild will involve disassembling the entire engine, inspecting every component, and replacing or machining anything that's worn. Performance upgrades (camshaft, pistons, etc.) will also dramatically increase cost.
Therefore, it's impossible to give a precise number. However, you can expect a range:
* A "budget" rebuild: Focusing on essential parts and possibly using some used components in good condition, might start around $3,000 - $5,000. This will likely require significant effort finding parts and a mechanic willing to work with a less-than-perfect parts inventory.
* A more standard rebuild with new or quality remanufactured parts: Expect to pay $6,000 - $12,000 or more.
* A high-performance rebuild with upgraded components: Costs could easily exceed $15,000 or more.
Before committing to any work, get at least three quotes from reputable engine rebuilders. Be very clear about the scope of the work you want done, the type of parts you prefer, and what you expect to be included in the price. Don't be afraid to ask questions and compare estimates carefully. Written quotes are always a good idea.
