does the Civic Si DC sports Header fit into a 94 GSR?
My friend is selling one that is why i ask.

 

I highly doubt it

 

if its a B series header, it will fit your car, but the problem lies in exhaust length. You'll have to get a longer or shorter cat.

if i remember correctly, the B18C's block is taller than the B16A's, so even if you could correct the length at the muffler shop, the header might not clear the oil pan. you could probably put a B18C's header onto a B16A and clear it but not the other way around.

 

yeah...the B18 block is about 2" taller, I believe. so the B16 header won't clear. The DC header that's made for the B18 barely clears the block.

 

my bad...well, there you go...

 

thanks for the info
