R32 GT-R Single turbo - Protect wiring harness

Hi,

For the guys that are running single turbos on their cars(whether R's or Non), how do you protect the wiring harness on the passengers side by the turbo?

I have a 9180 which a 4 inch dump, which I will get ceramic coated(exhaust/housing/dump) going in soon. I will be sticking the gold reflective tape on my exhaust side plus on the firewall anyway, but the poor wiring will get burnt to a crisp in no time... Also, will boil the brake fluid with the ABS controller inches away(That's another problem).

All I can see are 2 options:

a) Re-route the loom under the fender(Can you already by extended looms? Wiringspecialties dont sell one)
b) Heat shielding(Reflective tapes + metal surrounds and heat sleeves all around the harness.

Thanks.

Re routed over the strut tower after melting it the first time...

 

Also for longer term keeping heat out of the tower/ABS area, good quality wrap on the dump and also a good turbo beanie. That made a huge difference to secondary underbonnet temps i found.

Those fireproof sleeves are pretty bloody good.  If you can get any other more primary heat shield in there (even just the coating) it should be survivable.  If you want to exercise paranoia, you could slip a thermocouple in there with the loom at the likely hottest spot and see what it gets up to.  If you're comfortable, then leave it like that.  If not comfortable, then you plan to reroute the loom.

Tidiest and most reliable solution is to re-route outside the engine bay.  Get it right away from the heat source.

It's one of those mysteries why the factory routed outside on the right hand, and kept it inside on the left hand side.

Unplug the harness from the big 2 connectors near washer bottle and feed it inside your guard 

yes it fits as I have done mine and my mates cars far more cleaner, uncluttered and protects it from the heat

Which connectors sorry? Please indicate as per pics on this link(Found some reference pics on GTRUK) - https://www.gtr.co.uk/forum/175254-engine-bay-wiring-loom-run.html

Thank you!

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      By 180 wanabe · Posted

      Also had a look at the Nissan JP website looks like the 400r has a slightly shorter ratio than than the regular V37 3.133 VS 2.937 which from a guy who has driven both 3.69 vs 4.11 ratios in the S15 is bugger all. Seems that the AUTO Z runs the same ratio as the 400R but can't find any info as to if its an open or LSD? More often than not the auto LSD is open

      R34 power steering

      Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.

      Skid pans in/around Sydney?

      By Kinks · Posted

      I did a skidpan night at SMSP this week, it was much cheaper than $350. But yeah, you need to slap an LSD in that thing.  I put an OS Giken in the 370Z and it's f**king MARVELOUS even compared to Nissan's viscous LSD. So you're saying it's free now that it's a housing estate? 😂

      Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy

      Do you have an IAT sensor? It's worth checking it to see. You may be suprised how little gap you actually need to flood your engine with hot air. (I tape up my airbox for a reason) :p
