Hi Guys

Im doing an engine conversion in my car from an Rb25det to an Rb26dett. As per the mechanic the main thing i would require are for the conversion are

Rb26dett engine

GTR ECU

R33 GTR Engine loom

RB26dett rwd sump or rb25det modified sump

R33 GTR Chassic Wiring loom

I agree on the first 4 thing that would be needed but what i dont understand is why in the world would he need a chassic wiring loom. I have done some research on the internet and have called up XSpeed in WA and they have confirmed that I do NOT need the chassic loom because the only thing im changin is the engine so the ECU and Harness is all i would require towards electronics since ecu and loom connect to the engine and is essential for the running.

Can anyone else shed some light on this. Im sorta stuck in the middle where i want to question the mechanic on this but all i get is that he def needs it for the conversion. Im iffy on cross questioning him on this topic but can any let me know if for sure that the car will start and run as per normal if I decide not to get the chassic loom.

Your help asap will be good

You do not need the chassis wiring loom. The conversion can be easily made by simply modifying the RB26 loom with the necessary body loom plugs from the RB25 loom to make it a 'plug'n'play' loom. I have modified several RB25 looms to suit both R32s and a cefiro. I can only guess the mechanic is chasing the chassis loom to make it easier for him to understand the factory wiring. If he has a wiring diagram for the engine loom and pinouts he should be able to wire it up correctly. Its actually not that difficult as Nissan retained a large amount of similarity between the Rb20/25/26 engine management systems.

If I had the time I would offer to modify the RB26 loom for you but unfortunately I don't have any spare time for the next couple of months.

Hope this helps.

Cheers

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
