i have a JDM b18 type r motor. and im swaping it into my ek coupe..and i notice that the stock headres wont bolt right to the cat on the civic and i was wondering if a b16a si header will bolt on to the itr motor?

 

The deck height is too tall for the B16 header, so it will not clear the oil pan. But it does bolt up to the head, just won't clear.

 

might be fine my buddy had b16 dc headers and put them on his gsr so they may fit

 

i have a b20/vtec and im using the DC b16 header
its not stock but its kinda the same
