LS1 engine parts selection, anyone using them

[xrtim]

Hi all i'm building a twin turbo LS1, almost finished the manifolds and am looking forward to having a break from fabricating.
I have drawn up a short list of the components I want to fit and would like to know if any one is using them and can give me some feesback

Meziere 300 Series Electric Water Pump
Holley EFI LS Hi-Ram Intake Manifold (does it fit under the clam)
Megasquirt MS3 Pro
Laminova oil cooler
