What is the exhaust port spacing on the D-series and B-series engines? I have a flange for one of the two, that is about 3-3/8" center-center, and need to know which one it is.

Thanks!

 

Nevermind. I dug up some old CAD files and figured out it was a B-series.

OMG, I'm such an idiot.

I did in fact use a Honda B-series flange for my Kia manifold. But Turbopimp gave me the information I was after to begin with, in port spacing:

D-Series: 85mm - 85mm - 85mm
B-Series: 90mm - 80mm - 90mm

Kia flange: 86mm - 86mm - 86mm

So I should have built my Kia header with a D-series flange. I would have been .5mm off on the inner ports and 1.5mm off on the outer ports, which isn't even the thickness of the piping. Instead I had to make nasty gap welds and didn't know any better. Oh, well, live and learn.
