Yeah I'm leaning on 3076R with .6 housing, merge collector manifold, 260 Tomei cams in/ex, NissTune, 18 psi and all the supporting fuel and intake/exhaust mods.
My mates car just pulled 330rwkW on 18psi with basically that set up on a Neo so it definitely works.
If I could get a 35/40 on song by 3800rpm, I'd just throw one of them on the car straight away, but without serious head work I don't think it'd have a chance of flowing like that.
You got a build thread FineLine? Would be greatly interested to have a read of it and look at your development path.
