By the way, I asked Ozmo if this will handle a twin turbo LS. Here is the response:
We have static tested the manifold above 50psi, and I am confident it can handle up to 30psi on an engine (heat, vibration etc).
I have done flanges before to run twin ID2000 injectors on a 1500HP LS7 style head application - OZMO RS7 manifold.

Really nice bit of kit, but it won't work in my scenario.
Best of luck with the sale!
