Fixed it, sorry!
The manifold looks like a much cheaper way to go than a Greddy IM, with potentially more tunability because you can change the stacks... does that even matter though with forced induction? I know on bikes changing the stacks makes a huge diff with how the bike breathes.
And do they make a high-port version for the S13 head? I'd imagine it'd be easier to fit that huge plenum/throttle body/4" 90* elbow on a S13 head than the S14 head
What kind of gains do you see on the dyno (and in what rpm range)? It seems like that design would have all 4 cylinders breathing evenly (so no lean condition on #4 like some manifolds), and give you a nice kick in the middle and top like SR's need... so someone could stay with small duration cams (to help spool up a big turbo) and yet throw that mani on and get a nice top end. <== *speculation/curiousity*
And the all-mighty factor... how much $$$?
