How much and how long?...

[JLad10687]

How much does a typical engine rebuild cost and how long does it last?

Take the length of the engine, devide it by its hight, times by the square root of the number of years the mechanic has been married then adjust for alcahol consumed during the build.




Iv seen engines stripped and rebuilt in a day, and Iv seen engines that Iv pulled apart for a rebuild 2 years ago that are still sitting in bits in a workshop.



It depends on so many factors its not something you can easily give an answer to, share a little more details about your particular situation and we can be more specific.

Well, I mean my car has 124,000 mi on it. Its an 89 Nissan Maxima SE. I was considering getting it rebuilt just so it doesnt die on me and I can work on getting a project completed.

I was considering getting a 300ZX(I can only find them with 150,000+mi, and having the motor, turbos, and trans rebuilt).

Do not bother to rebuild an engine unless it is showing signs of extreme wear, including serious oil burning, significant blow-by, low compression and/or major internal noises that you are sure are due to worn internal parts.

Rebuilding an engine will not necessarily make the car more reliable, especially if the car has other serious wear and/or rust issues.

Finally, often its just the cylinder heads and valves/guides that are worn, yet the reciprocating assembly is okay. In such a case, rebuilt cylinder head(s) may be all thats required.

As for cost of rebuilding an engine, allow $1500 to $3000 installed. The price difference depends on the amount of parts replaced vs. refurbished.

For example, if valves are not too badly worn, they can be resurfaced and re-used with new guides, at a lower cost than new ones.

A properly rebuilt engine will last as long as the original engine did, often 200k miles or more. The life depends a lot on the type of use and maitenance the car gets.

Agreed with all of the above. Unless you're showing true signs of aging from that engine, it may last much longer.

A good rebuild should last as long as an original assembly. In truth some rebuilders kinda slap them together quickly and aren't too careful about being clean or accurate. They make assumptions on what things should be machined and what things shouldn't.

In general, Jasper engines is an excellent source for engines. At least if you have a problem they have a good nationwide warranty and a good network of authorized service places.
