What parts would be needed? And if the head and block are in good condition (roughly 150 thousand) Would it be a good idea to go ahead and buy it($200) and then have it built up? The way I see it is I can buy the engine since mine is blown, and have it rebuilt(upgraded) for cheaper than fixing my blown engine... What are your ideas about this?

It might be a good idea to get that $200 motor so that between the two motors you can use the parts that are in best condition.

Your blown motor may be OK to rebuild depending on what went wrong to cause it to fail.

You may find out that the cost of rebuilding both motors might turn out to be the same.

There's no guarantee that the $200 motor is in good shape; there may be a crack in the block or a defect in one or more rods; the crank may need regrinding, etc.

Some of the basic things that need to be done for starters is getting theblock boiled and magnefluxed, measuring the cylinders for out-of-round andtaper then determining if the cylinders need only to be honed or bored tothe next oversize. The crank needs to be magneflux and straightened then the journals measured to determine if they need to be reground to the nextundersize. The rods need to be magnefluxed and straightened.

The only thing wrong with my engins is I have a blown head gasket... So the guy said the head needed to be worked on.. Said it would cost about $1500.00. So I was just looking into Some things that I could do with that money....

Do you know of any "Build up kits" that I could look into? And how much does the Average build up cost? All I want is to have an engine ready for turbo.

There are many places that sell KA24 kits. Just do a search on yahoo.com.

The average full rebuild costs anywhere from $2,000 and up; this includes parts and machine work.
