External VCT

[rbs30]

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.

I did mine differently.Used a long jobbing drill, removed some of the deck for access. This way plenty of meat for the thread to grip

The external feed line is neat and tidy.

apparently I am blowing smoke out of my arse, rbs30 started the post then lost interest.

Hope it helps somebody out there

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.

Nice. I like it. I work in a machine shop so I could just mill that section of the deck away. I like the idea of 6mm of thread. Did you tap it 1/8 bsp same as the oil sender? Did you get that hose made at a hydraulics place?

[Rusty Nuts]

1/16 NPT male-AN4  Turbosmart fitting used loctite to seal. Yes got the hose from ENZED  can't remember how much but was less than $30.

Sweet as. Thanks for the info. Did you run a restrictor anywhere in that setup?

[Rusty Nuts]

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

[rbs30]

Cheers man

[Rusty Nuts]

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.
