I've got a friend willing to give me a DC header for next to nothing. It came off of a GSR. I was told that a header that fits one B-series engine will fit just about any other B-series engine, but when I was checking out a DC Sports website I saw that there were different part numbers for the GSR and Type R. Anyone have any ideas on what the differences would be?

 

gsr header is shorter thats about it and it doesnt have a o2 sensor in it

 

It might be a DC JDM 4-1 header which will fit on either a gsr or itr.

 

It might be JDM, but I don't know. Is there any way to tell? All I know is its 4-1, its ceramic, and its got an outer diameter of 2.25" and an inner diameter of 2".

 

Well it's not a JDM DC Header since the collector isnt 2.5''. What b-series motor are you trying to put it on?

 

Here's what I was planning on doing. My friend sold this to me for $150 bucks. It's in excellent condition. If it'll give me some extra horses on a B18C5 then I'll put it onto my Type R. If not, I have an 88 Civic Hatch that will be getting a B18A soon and it'll go onto that.

 

some might get a few extra horses but not nearly as much as what other headers can give (mugen, spoon, comptech, toda, JDMITR, Hytech etc.) Im also not sure but i dont think that vtec b series header bolt patterns are not the same as b series non vtec, but like i said im not sure on that.

 

I was told that all B-series motors have the same bolt pattern, although I do not know this for a fact. I'd like to ask your opinion. Since I have to buy an exhaust and high flow cat anyway, should I look for another header while I'm at it?

 

Go with a Spoon or a Toda header for your itr. If you don't want to spend that much money just stick with the basic JDM 4-1 itr header and put a heat shield over it to keep that stock look. I would recommend the DC JDM header, but the ground clearance sucks.
