like the topic says.

when i bought my swap, the header and the secondary pipe does not have the O2 sensor. it doesn't even have a location for the O2. also i've heard gsr's have the O2 mounted on the cat. true? what are my solutions and alternatives? TIA


* edit * can i drill into my header and thread it for the o2?

The 99-00 Si exhaust manifold and downpipe probably won't fit a GSR engine without some work. The B18 deck height is slightly taller than the B16, so the manifold won't line up correctly. Probably not worth the effort.

TwistedSI

Yeah, I don't think it will work and if it does it won't be right. Like yobtah said, probably not worth the effort. Go spend a couple hundred bucks on the right header.

cool, thanks for the replies fellas

ciRcuitJerk

it will work but you need to take it to a muffler shop to have it modified

gubo22

Anything is possible.
i'm modding the lower portion of a twin cam header for my sohc right now
its about 2inches too long.
cut and weld.

YES IT WILL WORK.... I have a b18c1 in my hatch and im using a 00si oem header.
all you have to do is take it to a muffler shop for the exhaust piping. gsr oem header is shorter and doesnt have the O2 bung, while the b16a2 header is a little longer and has the hole for the O2 sensor.

00 civic si header and b18c1 motor, fits like a glove

GripFactoR

jdm b18c + stock si b16 header + thermal exhaust for CX hatch = no cutting or welding... true bolt on.

dantastic

if anything, u could always get a 02 sensor bung welded on

Formula 1

nope your won't be able to get it on

GDM Z28

it will work fine. i bought a gsr header and put it on my b18b that was in my hatch and i didnt have to do any exhaust modifacation, it just bolted up. then i took it off and my friend with a 1st gen integ with a b16 put it on and it fit fine. but he had to go to a muffler shop.

***, thanks for the trust. if it fit a b20. then a b18 would def. clear the bottom end..

DA_CHEESE!

OMIGOD, talk about misinformation! YES it will fit! I have a gsr header on my b20.

Are you retarted son?? He's talking about using a dohc header on a sohc motor. I guess all of you guys who love your so called "DOHC" Vtec motors must not know what you are talking about. Only Saturns have two cams!

funny how everyone says it "fits like a glove" when my JDM 2 (b16a) stock header won't fit my LS/VTEC. Had to use a gsr header. I used a 99 civic si cat cause it has a place for a O2, gonna have a test pipe with bung made soon.....

Formula 1

ok no b16 header will fit a b18b/c/c5 ....u can get it on but it doesn't fit right the header will be huggin the oil pan....cuz of the difference is deck height and stroke...if you guys like that then do it i would say buy the right header for the engine and make the exhaust fit

IMO i would rather fit a cat and exhaust up to a header that is made for the engine that get a header that doesn't fit properly and try to mate it up with the cat and exhaust

1994 civic hb
b18c1 + 1993 gsr header + tanabe rm = bolt on no weld
and yes the si does fit too one of my friend has it on his hatchcrap

WOULD GSR HEADERS FIT A LS

Formula 1

gsr headers shoudl fit a ls on the height but i dunno bout the bolts on the flange and such

Mr Hammond

:sigh: you guys and damn deck height ****. How many people here have actually tried it before? I'll be not many. How many people here even know the differnce in deck height from a B16B/18B,C block vs B16/17A? I'll be again not many.

Just for reference they all have the same flange and bolt pattern design. The only differnece is length. You can either get a custom length cat or modify the exhaust. The hole "oh but it will not clear the oil pan" is just plain untrue.

I think everyone here should go to a junkyard, buy a 99-00 Si exhaust manfiold and go put it on a LS/GSR/CTR/ITR block just to see for yourself.

P.S. I Hearsay.

Formula 1

i but the dc sports 4-1 00 si header on my jdm 94 gsr and it won't clear the pan properly thats a fact

and btw the difference in deck height is about 6-8mm

dunkd

b16 header on 95 gsr... bolts right up, u can't use the stock gsr header b/c its too short.

a stock b16 header on a gsr will "touch" the oil pan... my friend has this... not hard but it does touch ever so lightly.
