So I'm getting frustrated with people delcaring that the Si is a 6th gen when the 06/07 civics are 8th gen. Just because Honda of America didn't market an Si during certain generations doesn't mean that the new Si isn't still an 8th gen civic. If you walked into a parts store and told them you needed a timing belt for a 6th gen civic Si, guess what: you'd get one for a B16 and not a K20! And yes, I specified Honda of America here...in Canada, they marketed the Civic EX as an Si, thus making a 5th gen (92-95) Si, even though we didn't have that fancy sticker on the american models.
Get over it, it's still an 8th gen Civic Si.
