The engine block cracked

First a disclaimer: I have no experience with the Honda S2000. But in other cars I have been-there-done-that. Any Honda is a well engineered car, including engine and for it to have a cracked block this soon, 7 or 8 years and 88k miles is rare. Unless neglected and allowed to overheat badly. I am not suggesting you did neglect maintenance and ordinary fluid checks.. or did you? That being said, get a rebuilt crate engine or the used and don't re-use same heads. They (the heads) were stressed along with block.

Replacing the block will still require all the gaskets, rings and bearings. I would look at a low mileage used engine only if there were service records available. If no service records, I would build an engine using a new block and the existing head (provided it was checked at a reputable machine shop).

I bought a crate motor from Japan for a car I had and had no problems. just make sure its the exact same one your replacing! I actually had them come pick it back up and send back the first one I got, it wasn't the same as my old one. So make sure its exact. but other than the shipping delay it ran great and I had no problems.

Crate engine would be great, but are they still available for the discontinued S2000? Will it be compatible if ordered from Japan?
