I have a RB25 Series 1 in my nissan 240sx and since this forum has helped me on more than a few occations thought I would post up my problem. I am trying to start my car for the first time since last fall and changing the headgasket, injectors, Power FC, and a few other odds and ends since then. Here is the latest from todays work:

I got the MAF recognized by the Power FC. (my dumbass had a SAFC last year and didnt hook the orn/blue wire back up to the ecu harness) And I figured out the 5volt issue (some harness wasnt plugged in by the fusebox under the hood)

But the car still isnt firing up. So if anyone with a Power FC has things for me to check on that let me know. I have Deatcshwerks 740cc injectors so I have the injectors set at 50% and 0.00ms on the latency right now. I did a sensor check and nothing is highlighted black now but what sensor "dots" should be lit up? Also when I am cranking the injectors duty cycle goes from .5% to .1% if I crank for more than 5seconds or so.

      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)

      Why are you so adamant on going M12? Why not follow Brad (GTSBoy) suggestion. You're talking moving from a 1/8" size, to a 1/2" effectively. 4 times bigger. Why skip the commonly available sizes in between? The bigger you go, the more likely you are to strip the threads out at a later date, as guaranteed, someone will put a huge spanner on the M12 and really tighten it up, and you're only in thin wall, so not a lot of threads to engage!

      Hi. Yeah thanks. Car is already at tuners and it staying there to resolve "many" issues they do not like. So it is in a good hands. Getting a good tune on that Nistune ECU too so the car would be good. Just needs a little tune up and love.

      Probably gonna remove manifold and turbo. I’m not sure if I can get M12 x 1.5 air tight. Could use high temp Loctite 246 or something similar, but I don’t know. Maybe it’s just best to remove everything again and weld an 1/8NPT on there instead.
