It's a TP dual plane low rise EFI and I just need some confirmation on the correct way to hook up my heater hoses. Does it go heater to water pump, water pump to manifold, manifold...

What I'm wondering is if I run a torquepower dual plane low rise and a quad throttle body, can I fit it under the bonnet? Coz I absolutely do not want it sticking out, that's not the look I'm...

    Intake Manifold

    Hey guys, I'm just wondering whether or not you can chuck the black VE upper manifold onto a VZ without any problems? Looks cooler wouldn't mind the switch up! Doesn't seem like it would make much a difference providing all the bolt holes line up etc!

    Remove inlet manifold or work under it?

    Coils, plugs, and inlet manifold gasket replacement...easier to to remove the whole intake manifold to do the work, or prop it up with blocks enough to get access? Time isn't really an issue, if it only has to be done once.
