Extrude Honing is somewhat expensive and the flat top is already somewhat oversized for most Miatas

It would be nice to get more info out of Skunk2 and Project-G (I believe there black NA is bing used) on the upcoming manifold being produced, but everyone is being pretty tight lipped.

Just as a data point my 01 would run like Emilio described when cold for about the first 1-2 miles. It might be different OEM tunes to play here.

I'm running a Skunk2 Ultra Street with the flange cut off and a new one welded on. It would be very easy for Skunk2 to release something similar. Performance gains over a stock NA8 manifold where massive.

Prefer Madjak's iteration.

Also because it's easier to see what's going on with his. We don't know much about the Junk2 unit, so i don't know if i want it yet. I do know i want his setup, though.

What's the holdup? He has laid the necessary groundwork.

I want whatever works best and doesn't cost a boatload. Oh reliable too.

Time is the holdup. And that i need a clutch first because my obscenely powerful 110whp car has overwhelmed my clutch.

Took 3 pulls on stock manifold.  Removed the VTCS butterflies and the shaft, used JB to close up the holes, and smoothed them up.  Took 3 pulls.  No change in peak hp, no change in plot shape, nothing.
