Dude - this is all done .......... lookie here:
Manifold : Manifold Nissan VQ35 -SF - Jenvey Dynamics
If I was interested in looking closer, I suspect this is the pattern for 1Slow's manifold, except that he installed spacers in place of the ITB's and CNC machined a f4rking great plenum for each bank and plonked some 75mm TB's from a Maxima in front of each.
