as far as i know the only reason to plug your EBC into the top of your wastegate is that it will put pressure on the valve which will effectively double your boost pressure..handy if you run out of spring pressure but want more boost....Do you want that??

In this diagram, which would be COM port and NC? I'm assuming left is COM, centre is NO and right is NC?

I want to get mine sorted and have just fitted a hypergate 45 with my power fc boost control kit.

A little searching turns up threads like these

 

The other thing you can do is think about what COM, NC and NO actually mean.  COM means common, and suggests that that is the port that will connect to either of the other 2 ports depending on whether the solenoid is powered or not.  NC means normally closed, and suggest that the port is connected to nothing when the solenoid is unpowered.  NO is normally open and suggests that when the solenoid is unpowered that it will connect through to the COM port. Power the solenoid and the status of NC and No with respect to COM will flip.

You can even prove this to yourself by blowing though the various ports of the valve and seeing what happens when it's powered and unpowered.  You can then work out for yourself which of the 3 ports (which on MAC valves are labeled 1,2 & 3) are actually COM, NC and NO.

The picture in your OP actually shows you which numbered ports to use on a 3 port MAC valve without even needing to know whether they are COM, NC or NO.

    • Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.
    • Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.
    • Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?
    • 1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
