First gens came with a d16..............I assume you have a civic because you have a d16. From what I hear, you might need a new driverside motormount , an si rearmount, axles and other b series part. That is if you have a civic. The b20 has the same mounts as a b18.
Dammit :facepalm: why do I always forget that >.< my bad. Idk about first gens. My mistake.First gens came with a d16..............
