i am ordering my motor today(ya!!!) anyways, i am also ordering a header,itr intake manifold,and ctr cams. my question is will i be able to fit a dc jdm 4-1 header on my car witht the stock cross-member or will i have to modify the cross-member? i am going to get the z-10 cross-member later but i need to know if i can fit the header in my current situation???? thanks guys

 

I had to notch mine to fit a header.

 

another question...what do i do about the 2 o2 sensors on my manifold??? seeing that the header i want only has 1?

 

header will not fit unless you change the lower x-member, z10 much better than the pos PlaceRacing that I have.

On the header, which is a good choice, I had my friendly metal shop put in two bungs about 9 inches downstream from top of header in primaries # 1 & 3, and stuffed an old O2 sensor in the old O2 hole. Works great and NOT expensive. I think that better and prob cheaper than converting to a single O2....
