got coil packs changed over from a mechanic, got the car back and the tacho is going crazy! mechanic says it is the instrument cluster/needs to be changed over with a new set (i have another set so it doesnt worry me) but i just wanted to know wtf it could be?

even when the car is just on but not started it goes past redline all the way it can go and back again, its like there is some kind of electric current making it go crazy?

it clearly doesnt work at all and its jumping all over the place, thank god i drive an auto.

any help would be great thanks!

I know this isn't the exact same problem as you but with my old gemini when I changed it over to electronic ignition it sent the after market tacho crazy. The ignition book mentioned it needed some form stabalizer kit for to give proper tacho reading. Maybe talk to an auto elec.

also another thing that could be related (no idea i dont know anything about car electronics) is my front left door speaker isnt working? i have pioneer splits hooked up to an amp. im hoping its just a loose wire or something.

hey mate,

the speaker not working wud be another totally unrelated problem.check your wiring,if the other channel on the amp is still working fine then your amp should be fine (hopfully) so it should just be a wiring isue.also check the connections on the back of the speakers (inside the doors).

      R34DE as in R34 with an RB25DE? So did you get this? Or you planning to?  I'm not really sure what you're saying.

      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)
