    I would say that drilling and tapping the intake wouldn't be too difficult on the N54. Get to it!

    They're pretty much all dry setups I believe.

    better to put it in the intake manifold or charge piping?

    oh no- If you're gonna do it, do it right. Direct port injection on each cylinder. Hell, there probably is enough room to make it work from the bottom :sneaky:

    Direct port is the way to do it right. More expensive but well worth it IMO.

    I bought a Evolution Racewerk charge pipe with dual bungs. One for meth one for nitrous.

    If doing a "wet" direct port setup...can the stock fuel system support that and where would one tap it? Or would someone have to run a standalone fuel tank for the this? Only reason I ask is I recall another N54 in South Africa which had a standalone fuel cell in the trunk.

    If I went down this route, I'd like to avoid that if at all possible.

    The only way I have seen direct port done on this platform is with a fuel cell.

    @boosted-M is running a wet setup and tapped into the factory low pressure fuel line. http://www.bimmerboost.com/showthrea...122#post480122

    If you're running Nitrous, I wouldnt ever rely on the stock fuel system.

    Separate fuel cell is the way to go...

    There is plenty of different ways to set that up. But running a separate fuel cell, fuel pump, fuel pressure regulator and lines JUST FOR a wet setup is about as overkill as it gets. We aren't talking a 200shot here. If you wanted to run race fuel, or E85 as the supplemental fuel than its understandable, but thats still alot of $$ to throw down if its not needed. An upraded in tank fuel pump and the fuel line T above should fit most peoples needs. I personally am kicking around the idea of running direct port with methanol as the fuel source, but i have a lot of researching to do.

    they make in tank fuel cell kits that are pretty "PNP".... i mean as PNP as you get doing something like that.

    do it once, do it right.

    Wet kits are overkill for the size shot we can safely run on stock internals anyway. We have seen 700+ hp on the VTT stg3 and FFTEC stuff but aside from the undercover 1series garth has I don't think anyone has attempted anything more than a .40 jet. There is still a ton of power to be found at that level honestly (more than I am comfortable adding without forged internals) so I run a .32 jet and the torque gains alone are massive.

    Anyone have logs showing AFR stability as nitrous hits? I would be afraid of leaning out for a split second.

    Another reason direct port is preferred.

    Well, wet shot really. Direct port is better distribution. I'm really interested to do a direct port wet setup using meth. That would solve the inconsistent meth distribution issue also.

    But you also are ensuring fuel delivery into each cylinder and even say if you have a tune with advanced timing you don't risk the dangers of running lean you do even with a wet shot.

    You could always do this... well, if you have an M motor:

    Thx for posting the link to my thread !i was running a dry setup but when nitrous activated my trims would max out... I run straight e85 and basically use the meth as a supplementary fuel supply to keep my hpfp in check.. That aeromotive fuel line adapter is sweet and took me 20mins to convert from a dry setup to a wet setup! Here is what my car runs without nitrous ( remember this is an XI Model) I hope to get nitrous times soon Click here to enlarge

    The JB4 has a 5V output that can be used to operate a N2O solenoid. The majority of the N2O control is in the JB4 software with all of the programable controls. With the JB4 monitoring AFR, IATs, Boost, etc. i see it as a very safe way to run nitrous. Some of the threads I linked above even talk about what settings people were using in the JB4 interface to control N2O.

    a 5V output is not enough to run a solenoid.
    it also isnt enough to run a standard relay needed for a solenoid.
