Hello.
I've found a replacement engine for my blown 2.5. It has done 151K kilometres or around 100K miles. It is affordable at around $2000k and is in the country. The car was running at the time of impact.

Would you consider this past the rebuild date for track use (trackdays)? Or would you just run it till it blows?

My other option is to have my engine sleeved to 2.9l and completely overhauled for the price of around 6-7 engines like this one.

The third option is to get a more expensive , lower mileage used engine from abroad, import it and pray it is OK:

Thoughts?
