Not a whole lot of information here but the manifold was on display at SEMA in the Greddy "Drift Concept" Supra and was made by Custom Plenum Creations. I've reached out to them about the fitment of the manifold for other B58 vehicles and any updates will be posted here.
Its really amazing to see the level of support the B58 is getting now due to the Supra, it seems there is no loser with a bigger audience. I'll need to check on the manifold flange for the older B58 and compare it to the new one before any guesses could be made regarding the fitment of this manifold on the existing B58 vehicles. It would seem safe to believe the new G29 Z4 and G20 3 series would fit without much or any issues.
