I'm thinking about putting an RB26 in my crown vic
you may have to massage the firewall a bit to make it fit

ey for when I buy my first car sometime in the future, should I buy a b-series civic or a honda crx?
ultimately I think that comes down to how much you're willing to spend. A b-series will generally be cheaper and easier to find even in stock form, whereas a crx is gonna be more expensive and way harder to find unmolested and if buy one pre-modded you may end up spending more money undoing mods that a previous owner did improperly, or ones you just don't like (of course the same could be said for a pre-modded b-series).
personally I'd go with a crx just because they seem like more fun to own.
