You can find ads for engines on ebay, not private sellers either. There are ads from companies. An H22 for around 2k and shipping like 500 dollars. Good engine for a Prelude. Only problem, don't know if they fit in a 3rd gen. You can always call companies and ask. Companies can really give you straight advice and know a lot. Yeah, they maybe trying to sell you an engine, but they want to sell you the right one, they don't want any complaints.
