2 or 3 isn't exactly a grand number in the scheme of things. You can MAKE anything work with the time and money, but the point is that it IS NOT a direct swappable b-series engine. You have to do your homework and usually talk with someone that has spent more time and effort along with throwing money at a problem to find a solution unless you plan on doing it yourself.

Again, get a B20A if you have an older prelude and need an engine. Otherwise, have fun lightening your wallet.
