^ There's a couple of vendors on this site, as well as members that have fabbed up exhaust manifolds.
I'm running an Absurdflow design and totally love it. TurboTim is the guy behind Absurdflow. There are quite a few other members using his exhaust manifolds.

Very true I was thinking more along the lines of a eclipse 2.0t manifold but the best part is if I get it for next to nothing and it doesn't work..no harm no fowl I just wasted a couple hours,right? I'm not in any way saying it will work just weighing my options for manifolds...

Seeing if the port spacing lines up is free.
Better yet, here it is from my 2G (DSM) mani:
Ports are almost exactly 2" across. Maybe another 32nd or so. Space between ports is approximately 1 and 9/16". Ports are about 1 and 3/16" tall.
So in order to shut this topic up as everyone wants to, someone measure a BP mani and lets us know that its totaly different.

Google works better from a different computer...or I suck at searching.
Anyway, here is a jpg of the BP flange:
https://www.miataturbo.net/forum/att...ust-flange.jpg
The ports are 1.89, which will work OK with the DSM ports. The BP ports are 1.18, which also works well to the 1 and 3/16 of the DSM ports. Some matching with a die grinder and you are in business there. The diagram seems to indicate a port sapcing of about 3" on-center, where the DSM is right around 2.5" I am not sure I am reading that right though.
I will check bolt holes, but my guess is that it will fit well with some slotted holes and port-matching.
