Locost with VVT EFR and MS3x
Here are couple of photos of my Locost 7. Planning to run couple of track days and hillclimbs this year with it.

On my quest to make EFR work as well as the previous Garrett, I used external wastegate which is below the header. That way I can put the boost pressure on both sides of diaphragm, and control boost by bleeding the pressure from top out.
Wastegate dumps into separate exhaust.

No need for an EWG to make the EFR work. Turbosmart makes an EFR-specific twin-port actuator, and the standard wastegate will always flow better than an EWG tacked onto the side of the manifold.

Short but not quite half an inch.
The intake manifold is exactly this one.
