GTSBoy Posted October 7, 2013 Share Posted October 7, 2013 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.

0zhiph0p Posted October 7, 2013 Author Share Posted October 7, 2013 Sweet so it will be ok till I get power fc and tune, does anyone have a happy snap of where this little sucker is located or will a search on the forum be easy enough?

XRATED Posted October 7, 2013 Share Posted October 7, 2013 ...seriously, have a look into a nistune. half the money of a PFC. Link to comment https://www.sau.com.au/forums/topic/432929-modifying-gtr/page/2/#findComment-7054837 Share on other sites More sharing options...
GTSBoy Posted October 7, 2013 Share Posted October 7, 2013 If you couldn't google up a howto on pulling that restrictor in less time that it takes to post your last question, then I'd be extremely surprised.

0zhiph0p Posted October 8, 2013 Author Share Posted October 8, 2013 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 Link to comment https://www.sau.com.au/forums/topic/432929-modifying-gtr/page/2/#findComment-7055990 Share on other sites More sharing options...
portaz Posted October 8, 2013 Share Posted October 8, 2013 It usually has a coloured band around it but most are already removed what does you boost gauge go up to?

Blackkers Posted October 8, 2013 Share Posted October 8, 2013 I can't tell you how pleased I am with a Nistune ECU.

Count Grantleyish Posted October 9, 2013 Share Posted October 9, 2013 What does the boost gauge read? Should be .7kg/mm from memory (been a while since I've had a gtr).

0zhiph0p Posted October 9, 2013 Author Share Posted October 9, 2013 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 Link to comment https://www.sau.com.au/forums/topic/432929-modifying-gtr/page/2/#findComment-7057742 Share on other sites More sharing options...
Manuel Kasko Posted October 9, 2013 Share Posted October 9, 2013 Hmm could be a loose earth or even dirty AFM Is there any particular mods like a vent to atmo BOV Link to comment https://www.sau.com.au/forums/topic/432929-modifying-gtr/page/2/#findComment-7057907 Share on other sites More sharing options...
0zhiph0p Posted October 9, 2013 Author Share Posted October 9, 2013 Nah just stock bov, could it be a fuel pump related problem on its way out not pumping properly, although while driving its fine Link to comment https://www.sau.com.au/forums/topic/432929-modifying-gtr/page/2/#findComment-7057985 Share on other sites More sharing options...

sleptema Posted October 10, 2013 Share Posted October 10, 2013 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?

0zhiph0p Posted October 10, 2013 Author Share Posted October 10, 2013 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 Link to comment https://www.sau.com.au/forums/topic/432929-modifying-gtr/page/2/#findComment-7058751 Share on other sites More sharing options...
Anfanee Posted October 10, 2013 Share Posted October 10, 2013 Sounds like you have Partially blocked injectors or your coilpacks are on the way out. Sounds more like Fuel to me though..

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