 I noticed that the Atkins wrap around manifold he sells for the 6 port is a 4 port but I don't know if the bolt pattern is the same, maybe Kathy can comment on that.

The bolt pattern is the same, but I don't see any way to gracefully make the wrong style manifold work properly.  Attached is a pic I took back when I was collecting manifolds.  Clockwise from the top left is the stock turbo manifold, Atkins wrapover, Atkins straight, and Mazdatrix modified 4-port manifold.  The Mazdatrix was modified again later, with better flow, and MUCH better welding, and it's the manifold I'm using currently.

  Looks like the Atkins manifold is made for the third gen engine and he uses it for the six port also.
  Wouldn't it be better to use the third gen side housing at this point? looks like they would put out better power.
