where abouts are you going to drill for the nozzles?. Any chance of some pics ?.

Sure.
As close to the petrol injectors as my (un)steady hand will dare 
Didn't take any photos of marie's
two thirds of an engine 4pot manifold, but it was straightforward. I think I got a bit close to the gasket sealing ring with one of them. However, I was drilling from the outside which I've learnt is not the best policy. Probably better to grind yourself a flat where you want the outlet from the manifold face side, then drill into it because where you emerge on the "outside" of the manifold isn't as critical.
Start off with a small drill bit (2.5 mm for example) and get a hole drilled then inspect it both sides to make sure the hole will take opening out to the full 5mm without fouling anything. You can always move the hole slightly by aiming the next size up slightly off centre.
I used 2.5mm nozzles on Marie's engine and upped the vapour pressure to 1.1 bar and it was spot on. The vapourisers (aptly named at the moment
) seem to come set at 0.8 bar or less at the moment so they need upping in pressure a bit. Remove the "voltran" name label and use an allen key to screw in the plug a turn or two while watching the pressure.
