I had to get my mixing manifold modified, an unmodified inlet would contact the manifold. Unless he changed the design recently, there have been 2 others that have had to do the same. It's not that big a deal, Abe modified it for me.

Yep. I asked Abe and he said there was a minor revision and should have no problem clearing the manifold. I should know more in a couple weeks!

Progressed it a bit today

Slotted the actuator bracket and bent the actuator arm so I could keep the actuator away from the chassis rail and fine tune its position.

Also a few more collector pics

Weekend's working fitting and welding up the downpipe

The Borg Warner turbo turbine V-band isn't a standard v-band design. So I had to modify the eBay purchased one. You cannot source the BW v-band flange or clamp here. The turbo company sold me a Vibrant flange and clamp and that didn't marry up either.

I know it's been a while for this thread, but I want to chime in about my manifold design. I wanted to get the most power pulse scavenging effect from the engine firing order. Notice that the 1-3-4-2 firing order in my manifold occurs in a circular order in the manifold collector. It was a feature I wanted in my manifold, as for the difference in power, I do not know how it compares to the offset firing order in the collector.

My manifold:
_ _ _ _
(2,4)
(1,3)

Others:
_ _ _ _
(1,4)
(2,3)

Yup, I too went circular on purpose.

Really doesn't matter. There is enough back pressure in the turbo manifold to offset any type of flow caused by rifling if the firing order in an open scroll manifold.
