I bought my 87 crx-si from a member on here and he said the engine was rebuilt and I believe it was but who ever rebuilt it didn't pay attention or it had a slight knock and at least it made it home before it through a rod threw the block. but the transmission shifts like butter and the dc sports header is brand new and according to the guy I bought it from it has a new clutch kit in it. i'd say the head is still good but I am not 100 percent sure I have gathered all my parts to swap in a b20v so I have no need for any of the d16a1 parts would like to sell as a package deal. just pm me thanks hope my post did not break any rules it is the d16a1 brown top 86-87 engine the dc sports header will fit any d series Honda engine
