hello all,

I have a question, tried searching and found nothing so please bare with me cause I know this might be an easy question, but I need help.

I plan on switching headers soon, the person im switching with has a vtec engine and I do not. Will these headers fit on my B18 engine? His header does not have an o2 sensor but I know my header does, so hes going to drill a bung so that way it would have my old o2 sensor. Is this ok? or would it affect performance having this welded in, i assume?

 

You're going to have to be more specific on WHICH model B18 you have.

 

And welding in an 02 bung is not a big deal, people do that all the time with aftermarket systems to incorporate a Wideband.

 

what kind of engine is the vtec engine that they are on?

 

I have a b18b1 mines a 2001 GS, and i think his is a 97 ls vtec.

 

The B-series heads are all the same bolt pattern off the head. That part of the manifold with bolt up with no problems.

The part you will be concerned with is the collector. The length differs from car-to-car. i.e. the length of the collector on the 98 Integra GS 2-door is different from a 2001 Type-R.

 

It sounds as if your friend has a '94-'99 GS-R header, in which case it will be too short to fit your exhaust without modifying the B-pipe.

thats usually the only problem when coming to buying different headers.

This car has a full skunk2 catback system. does this make a difference, so it wouldnt be short?

 

Is the cat-back from an LS or from a '94-99 GS-R?

its a skunk2 catback '94-01 GS/LS/RS

 

It will be too short to work with the '94-'99 GS-R header.

 

not that i dont trust you, but can anyone else confirm that it wont fit?

one thing ive discovered is that a b16 header wil not fit on an ls integra.

 

1994-2001 RS GS LS / 97-01 Type R
2000-2001 GSR
^-- For these models, the header all the way to the catback exhaust is interchangeable.

1994-1999 GSR's a pipe is a bit too short as shown in the picture and what everyone has posted.
