if your not going to do much engine modification then get the jdm b20a. your tranny will bold up with no problem.

if you diside to go with a h22a then you've got your work cut out for you and I wish you good luck . it will be a great learning experience for you. you'll also need custom motor mounts to fit the h22 in and do some fab. to the firewall as well.

civic and integra b series engines are two entirely different entities. prelude b series engines were actually designed for boost. honda just forgot to add the turbo manifold and the turbo lol.

bottom line. get the jdm b20
