hey ppls

wheres the boost restrictor in a 33 gtr ? i just wana see if its still there. From my searching i think im looking for a pipe with a yellow ring around it.. ? and its meant to be near the strut / pcm valve thingy ?

cause ya i dont see anything in that area or anywhere that looks like a boost solenoid (like a gtst one im assuming).

i can see 2 pipes with yellow rings but there going into the fuel stuff so i dont think its them.

ive attached a pic :)

thanks

Just wondering what you mean by boost restrictor? Also wondering what that "PCM valve" is. I thought that valve was the factory boost control solenoid. The reason I ask is because I am not running it anymore and it seems like my 26 is overboosting. It will easily boost past 14 psi and I dont know where it would stop since I have been taking it easy since i noticed it. Just wondering if there is any connection or if one or both of my wastegates is just messed up. Not trying to thread jack just trying to get some info. Any help would be great.

im not 100% either but there meant to run a stock solenoid to control the boost. and i think theres a little restrictor thingy in one of the pipes.

Go to your boost control solenoid - the cylinder laying on its side with the gold band and mount near your drivers side strut tower. Pull back the protective cover on the pipe going towards the front of the car attached to the top of the boost control solenoid.

If you feel down that pipe about 50mm you should feel a hard section near the yellow painted ring. There's the restrictor.

Cheers

      Looking for parts for 2003 V35. Specifically a working OEM stereo and passenger side window motor.

      Thanks to @V35_Paul there is an oem stereo available on gumtree, but the fascia is slightly different. It has a flip up screen as opposed to my pop up screen. Am I able to disconnect the radio/cd player from the fascia to use it on mine?

      Lets play a game - What is causing my oil consumption?

      By Dose Pipe Sutututu · Posted

      Had to google what a quart is lol.. so rough as guts a litre. That's a bit excessive, also what oil weight are you running? The whole steam cleaning idea isn't too far fetched either. Maybe as you suggested, turn off the WMI (assuming your Kebabtech pulls timing, boost, etc.) and run it for a bit and see if there are any noticeable changes in spark plug colouring.

      Is this pressure plate warped? And do I need a new one?

      By joshuaho96 · Posted

      Pretty simple question. I was about to put the transmission back in and thought I pretty much had it lined up when I noticed it seems like the pressure plate isn't flat. I was pretty careful when undoing the bolts both during initial disassembly for cleaning and when torquing them up for installation so this is pretty discouraging. I'm not sure if I accidentally bumped the pressure plate with the input shaft and bent it somehow or if it just showed up this way. Is it possible that there's just something obvious I'm not doing correctly? I'm pretty sure I was extremely careful to make sure the friction discs were seated correctly in the hub, everything lined up, flywheel torqued according to sequence, the little springs all sitting correctly in their seats, etc.  What's the play here? Do I jump straight to a new pressure plate?

      OK. I can see that being the case. But if you live in the land of "only switching between 4.08, 4.11, 4.36" like most Skyliners, then you never encounter it. Now I perhaps understand why the crownwheel is thicker on some of the smaller numerical ratio diffs. The two stubs being the same (unequal) lengths and just swapped side to side between the different cases is a new one to me. I'm hating Nissan R200s more than ever now.

      RB gearbox options

      Reason I say this is I have seen broken ones, in drift, drag and even behind a stock Z. I do appreciate most of the time its the synchro's that go.   Trouble with quoting HP is it doesn't really say how strong the box is.  I've not seen many CD00X box's make it past a mid 9(150mph) I have seen about a stock R33 RB25 box's run a 9 too, they all go boom at some point though.   Another clue is they make gearsets for CD00X box's too, wouldn't be a market if they didn't break or have a limit people are going past.   I totally agree it is a strong box, just have to weigh up the true total cost of the conversion vs rebuilding with a good gearset.
