Just to double-check, is this plastic design chosen for economical purpose as well? IIRC, a brand new VR38 lower intake manifold runs for around $500. I wonder if a group buy would help cope with the development costs.
Also, assuming we'll be using the standard VQ37 gasket for the manifold to meet with the head and VR38 gasket for the intake plenum. Are there benefits to using a thermal gasket?
