hi there, i am in the process of installing a rb25det in my nissan cefiro, my car is auto and unfortunately the engine i got is manual,,, apparently the loom is different with respect to the t.p.s,, can anyone tell me if there is a way to physically wire in that portion of the t.p.s into the loom? or maybe if there is a part of the loom that just have to plug into the manual engine's loom?

i know from the R31 the TPS has something like five connections

switch for idle/full throttle (auto/manual)

variable resistor from idle to full (auto only)

even though I had a manual loom, the wires were there for an auto TPS

the three TPS wires for auto in the wiring loom goes via the ECU to the transmission to the auto trans computer. ie the ECU itself doesn't even use the TPS auto variable resistor

if it is anything similar to the R33 you might notice the same thing. i know that ECUs are auto/manual but this is mainly mapping changes for load and injection cut off

visit www.gweeds.net as this guy transplanted an RB25 into a VL turbo and rewired the entire loom! hes got wiring diagrams on the site also but i couldn't get it working last time i visited

i would split the cefiro loom where these wires go to the A/T and put these into the RB25 loom

good luck!

      What should I do next to hold the head on

      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)
