i came accross a dc 421 one piece header and it said it was for a b16, 99 civic si... well it also said it can fit some other b- series engines but may require fabrication... well i was wondering if they will fit my 93 integra ls b18, with no or just slight modifications, and what needs to be done to them? here is the pn HHC5504 .

thanks

 

it will bolt up to the head and fit... the flange on the end of the downpipe may be angled the wrong way to bolt up to the cat though.. that would most likely be the only modification you would have to do..

 

also, as mentioned in this thread

I am not sure that it works the other way around though, yes, a b18 header would fit on a b16 head because the bolt pattern, etc is the same. However, b16s are shorter than b18s when measured from header bolts down to the bottom of the oil pan. So, a b18 header works fine on a b16 (leaves a little bit of room under the oil pan), but a b16 header will often hit the oil pan on a b18 because the bend in the header occurs too early.</TD></TR></TABLE>

 

k thanks... damit... it was a hella good price too, like 175 for almost new dc headers!!! ahhh
