Nitrous port positions Quite pleased with this purchase. A nice fabricated inlet manifold complete with fuel rails and all the fittings. I'll be able to fit my 72lb/hr injectors to this one as well. It's 3" taller than the stock LS1/6 plastic inlet, but should still fit under my hood with the large scoop on it.
It takes a 105mm throttle body too.
One thing I need to consider is where to put the nitrous ports - or whether it even matters?
Either spraying directly down behind the injectors in the runners, or I am considering whether it would work if I put them in the sides of the plenum (arrowed), squirting directly above the bellmouths inside. I can't decide at the moment. The plenum is made of 3mm sheet, so I could just drill and tap it for the nozzles. Otherwise it means making and welding some bosses to the runners at the right angle to fit them to.
I'd like to decide before I get to the point of fitting it, just so I don't have to take it off again at a later date...

Thanks Brandon. It's being fitted to the LQ9 motor that's going in my 2nd gen Camaro over the winter. 
I'll see about making some bosses up and welding them on.
As for the make of the manifold, dunno. It's off eBay and is Chinese made. But it appears well made except a few unfinished edges. Jig built and seems to fit ok. It's complete with fuel rails and all of the AN fittings and cross over lines too. So I'm pleased with it for the price I paid. As for flow, who knows. But it looks like it should work pretty darn well.

I'll probably be after a wet, direct port set up in a few months, I'll get the motor built and running first....
But whatever, you're currently top of the vendors list.
Are you good shipping to the UK? Kit less a bottle I expect.
