hi

my r32 gtr came with no heater hoses and my cd workshop manual doesnt show them.

I can tell the bottom hose at the heater  is the long one but at the motor end does it go to the block inlet or the pipe coming from the thermostat housing :P

thanx

As it happens I'm doing mine at the moment as I have the plenum off and decided to replace all the hoses so I only have to do this once (in theory). The heater hoses actually aren't all that expensive from Nissan (well I didn't think so anyway.

As you've probably seen there are two hoses attached (or should be in your case :D) to pipes that pass through firewall on the passenger side near the ABS actuator. The bottom of these hoses is the 'longest' - it runs behind the engine to the drivers side, angles down near the clutch master and then attches to a fitting at the back of the block above the starter motor. The second hose is actually 2 separate hoses that are joined at a sensor behind the motor near the ignitor box. It pretty much follows the same path as the first hose, but joins to a metal tube arrangement attached to the bottom of the plenum. The metal tube feeds into a fitting near the thermostat housing via another short rubber hose.

After all that I'd say it would be very difficult to replace the hoses without removing the plenum and it all becomes obvious once it is removed.

If you want I can give you the part numbers for the hoses and they're probably around the $100 mark for them all.

ugboot do you have more pics of that 34 in your avatar?

sorry im no help for your question...

hi danh

i have more photos, its my 200mm nitro RC racer tho not a real 34 but it is 4wd 2spd auto makes 1.38hp at 38000 rpm I havnt raced it much since I got my gtr.

Excellent reply thanx

Im having trouble getting the long one onto the block fitting trying to do it from underneath after i moved the starter out of the way.

I bought hoses 1 long + 1 short =$96 and 6 plenum gaskets =$25 so i need the other short hose  plus the sensor(sensor joins the 2 short ones???) 

wasit easy to get the plenum off while in the car???????

I intended removing it but was gunna wait till i got a oil filter relocation kit. and do it all together

Ive got a couple of days wait for a new radiator so i wanna do the hoses and the timing belt while the rad is out but cant afford the filter relocation yet. then off for a run up to brisbane.

There are inlet and and outlet hoses to the heater core at the firewall. One of them is a single long hose, but the other is made up of 2 shorter hoses joined by the sensor. Nissan sells the hoses individually, so there are 3 hoses + the sensor. On top of that there's another short hose near the thermostat (you probably can't even see that one.....if it's there in your car (??).

Plenum was easier to get off than I expected, but still fiddly. The 'secret' is to unbolt the small 'sub' plenum from the main plenum (the 'sub' plenum has the AAC valve attached - in fact it's best remove the AAC valve first). You also need to disconnect the fuel pipes plus a few other small bolts attached to the bottom and side of the plenum - all good fun as it has to be done by feel (ie blind). I also found I needed to use a range of 12mm spanners and small sockets to get the plenum nuts undone.

I'd recommend doing all the hoses, etc after you take the plenum off.

Heater hose PN's:

92410-05U00 - long heater hose

92402-05U00 - hose from engine to sensor

92401-05U00 - hose from sensor to firewall

27724-05U00 - sensor

14055-05U11 - hose at thermostat housing

      @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation.

      If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.
