Im sure this has been covered a few times, but last time i built an RB30 i deleted VCT. I want to use it this time. 

I see some people say to just drill and tap into the gallery on the head, and others weld a -3 fitting. Trying to figure out the best way to go. How thick is the aluminium before you get to the gallery? If its thick enough i guess a tapered thread is fine but wasnt sure if a weld on fitting would be better.

Lol nah man not blowing smoke out ur ass. Keep getting sidetracked every time I try to respond haha. So that looks like it goes down just in front of the solenoid does it? Have you had it going yet? Looks good. I like the idea of having a bit more meat there to tap

Its been running for a year, works perfectly. This method over 6mm of aluminium to thread through, just had to buy a new slim tap holder as mine was old and gigantic. This method the oil is directed exactly where the gallery leads to anyway. See picture 2  I aimed the drill hole at the centre of the gallery plug.

Neo doesn't need restrictor so no for mine, but earlier models do need restrictor

Although there are others who have done the conversion who have not used a restrictor. But I think they used a smaller diameter feed line. IMHO because I have tapped off a feed with a restrictor in the circuit above it the pressure would be right but perhaps the volume may be larger, which I figured wouldn't matter because there is restriction in the VCT valve itself.

    • Just planning to have the wiring neat and hide as much as possible.
    • The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.
    • Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
    • You can probably scrub the rust with a toothbrush or something. After you get the rust off flush well with water to neutralize and you will probably want to also use a fuel tank sealer to keep it from rusting again.
    • The sodium citrate solution is designed to buffer the citric acid to keep it from attacking metal quite so much, the guy that came up with that recipe did a ton of testing on how much metal loss occurs over time and it's nothing crazy unless you forget about it for months:
