What all would I need in order to come out with a successful crvtec transplant into the EG civic hatchback?

 

do a search, this has been asked/posted about a million times. check out:

It's the same as any other b-series swap into an EG, except your b20 intake manifold might be too tall to clear your hood so you'll have to use an LS manifold. also, the b20 tranny will not work, use any other 5-speed b-series hydro tranny.

 

There's also a compression ratio difference between the b20b and the b20z.
