The point of it is that Nissan Japan sold the GTR within the existing "Gentlemen's Agreement" that said no manufacturer would release a car with more than 205kW (or 206, or 207 or 208, depending on who you listen to). The restrictor was put in the boost control system to set the boost to a level that would stay pretty much within the gentlemen's agreement, but was trivial to remove and make GTRs close to unbeatable on the street (which was one of their highly desirable aims, of course).

The ECU will happily run the engine with that much boost, but it wil be richer and more retarded than if it was tuned properly. Rich and Retarded is a little safer on the engine. Well, the richer part certainly is. Retarded can be less safe sometimes. But I digress. Yes, for 15 years after the release of the R32 GTR people would simply pull that restrictor out and just drive it round. No problem.

So I think I took the right line off and looked in the hose and can't see anything, how far down will it be? I'll upload a pic maybe to make sure I have the right hose. Maybe previous owner already removed it

The boost gauge just goes to the top 7+

On a side note/question I started my car this arvo after being parked for 1 hour maybe and it just stalled then I started it again and the idle was

Real rough like it was going to stall but I kept the revs up a bit, this has also happened once before any ideas what it may be?

Once driving its fine both times have been on startup

Hmm could be a loose earth or even dirty AFM

Is there any particular mods like a vent to atmo BOV

The only way a bov would effect the car on idle would be a seriously rooted spring, and the problem would a hell of a lot more noticeable during boost, in for form of no boost.

Did the splutter only happen after stalling? Or does it just randomly happen on startup?

Yer it is randomly on startup, it stalled then when I started it again it spluttered a bit and started dropping revs but I gave some aceleration to bring the revs up for a couple of seconds then it was ok held fine on idle

factory bovs are slightly open at idle due to the manifold vacuum acting on them,(and don't leak under boost) so I would assume some after market bovs could be the same.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
