i have an opportunity to get my hands on a dc sport header that came off a civic si (b16) for dirt firkin cheap. i will be purchasing this header regardless of it's compatability(for resale). what i want to know is: will this header fit on my integra LS' B18B? i know that intake manifolds are completly different, and the exhaust ports and mounts match, but i don't see that the header is listed anywhere as universal.
please help

not sure on the flange, but the header may have clearence problems with the oil pan. b16 blocks are shorter than b18 blocks.

 

I don't think it will fit. The B16 header is quite a bit shorter.

 

yeah if you're not sure, just check the Part # off of DC's website, but im pretty sure the header is a little shorter than the b18 header

 

A header for a b18 will fit a b16, but it won't work the other way around. Like the other guy said, you'll run into clearance problems because the b16 is shorter than the b18.

 

which dc header? there are 2 for the B16
this one 4-1 header

or the 4-2-1

it's the one piece 4-2-1

 

it will bolt up to the block but i think the flange is different and the Si header might be shorter so you would have to extend you exhaust
