Hi, im a first time owner of a GTR, been lurking the forums for awhile, looking at builds etc but now i finally have my r32 gtr that ive always looked forward to owning. Ive been having a problem with the car stalling on deceleration to a stop here and there (started occuring 3 days after i owned it, drove fine before), ive looked into it on the forums about similar issues, and originally thought its due to having a atmospheric BOV but after having a look, it turns out mine was stock. So second conclusion i came to was it mustve been blocked off somewhere (probably at the BOV) to achieve the flutter.. or a more "whoosh" sound, so i woke up today and drove to my mates which is a 40min drive, to use his tools and try get to the bottom of it.... surprisingly drove fine the entire way there... and back. Anyways, so i assumed it wouldve been blocked off at the bov so jacked the car up, took the bumper off.... bolt under indicators was a PITA to get to, indicator didnt wanna budge, but after getting the bumper off and getting to the BOV i found out it wasnt blocked there, so decided to try follow some of the hoses back up, and next to the exhaust side i found 3 hoses that were blocked off with nuts.....(Prob was smarter if i had a look through the bay before i pulled bumper off but yeh..) I have a feeling it might be the hoses that recirculates the vented air back after the AFM and before the turbo but im not 100% sure so i took a photo and hopefully some1 here might be able to verify that that is the hose so i can sort this issue out.

Ive ordered few bits here and there for the car, waiting on them to arrive so wanted to figure out this problem asap so when everything gets here i can bring it to my mechanic and save some time. Ive attached 2 photos of the hoses that are blocked off and hopefully som1 wud be able to help me out and verify what they are? Sorry for noob question =P

It can be worrying when you first see that they connect to nothing with a bolt in the end. Don't worry.

You may also find plugs not connected, again don't panic.

These hoses have been blocked off on purpose. Likely by a mechanic and with a good reason.

Some you find wont have bolts and act as breathers.

Hopefully some one can name them for your from the pics.

Top pic appears on the ABS sides so I don't see how that can relate to the OEM bovs.

Charcoal cannisters etc... are normally blocked off.

You may also find a small number of hoses if you look for them on the plenum side. near the fuse box.

It's good to find the source and then label them with white pen. what they are for. (Eg: Diff or sump)

Especially if the engine's been built and/or aftermarket bolt ons.

Generally just needs the end to be raised pointing up to let gravity work.

@Sinista32 oh ok, cheers for that, i was hoping it would be related so i can conclude that it was those lines blocking the bov from recirculating the air back in. Ive read up on where its meant to circulate and its so far been mentioned after the AFM and before the turbos so where i found the hoses looks like it was roughly in that area, i think one of the hoses i saw i managed to trace it back to the intake so thats where my theory came from. Thanks for the input, appreciate it and the tip =) hopefully som1 would be able to clarify for me

      Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?

      See if you can thermal epoxy a heatsink or two onto it?

      The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.

      And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R

      So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
