G'day I've got a R32 GTR and have been getting smoke coming up through the rubber boot under my leather one on my gear shifter.

it doesn't smell like oil and am a little worried about where its coming from, has any one had a similar problem?

it only appears when doing anything above 70k/h

I've noticed this with my 25 box, seemed to be after sitting on 100kmh down the highway for a while.. never figured it out.

First time I saw it I thought there was wiring on fire but it didn't smell like burning insulation or even oil, my only guess is it was steam coming from condensation in the box (it is open to atmosphere after all).

Yeah same with my 25 box!! i freaked when i saw it as i was bring the car back to TAS from Brissy! but doesnt smell like anything at all, so I think also, that logically, it would be some kind of condensation

I've had this problem myself when i had my 33 i thought it was a problem with wiring as well lol.

Talked to my mechanic about it and he has seen the same problem before it turns out its the rubber boot around the gear shift, mainly happens in 5th gear as thats the biggest stretch for it.

We ordered a new boot from Nissan for like $20 and it never happened again, and yeh it was like a white smoke but didnt smell like gear oil at all but was def coming from the gearbox.

Cheers.

Yep same with my 32 GTR.... Only notice it on the highway. The gearbox does have two breather pipes (i assume one is the transfer case). I've been thinking about extending the lines into the airbox to just burn it, or back past (ie downwind) of the shifter location to see if that stops it coming inside.

That sounds like a plan cheers for the tips

Yeah well my 25 box only has one breather so you're probably assuming correctly ;)

Guess I'll get myself a new boot too.

OH! cheers! rubber boot right down at the base of the shifter you mean?? when i first experienced the white smoke i was gonna cold bail out of the car thinkin she was gonna blow!! hahaha

There's two boots;

1. Gearbox to shifter

2. Body to shifter (over the top of #1)

On mine 1 is broken, and 2 is loose, so i've put a cable tie around the top of 2. Might as well made sure they're both in tact and airtight.

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      This might be true if you live in NZ but I can't see how this could be true for us locals here.  I've found the customer support for Haltech to be absolutely amazing. I've turned up to Haltech and spent entire days with their tech support guys, they've even helped me with wiring dramas that had nothing to do with their products.  They have the best customer support of any company I've dealt with, I can't imagine how my experiences with them could possibly be any better.

      If you want to do a single throttle body conversion easily, you won't need to pull anything apart. Take the linkage from your throttle off the linkage controlling the ITBs. Now open the ITBs wide open, and lock the linkages in said position. Now add a single throttle body onto the front of your inlet plenum. No it's not ideal for the last nth of a kw, but it'll be a lot better than what you're already trying to do...   PS, ITBs can be so damn hard to tune from, because roughly 20% movement in a throttle body equates to a change in roughly 80% of its flow (Hence power). When you add up the flow limitations of those small throttle bodys, it is a LOT higher than that of a single large throttle. Hence, TPS is very very sensitive with them, and you do a LOT of work with sensor fusion, and some Maths behind the scenes to make those blends nice, and be smooth.

      Yep, when Haltech purchased Adaptronic, and all of the Adaptronic staff, including Andy went with it, it took Haltech to the next level. Haltech wanted Adaptronic as they wanted things like Andy's fuel models, and some other IP, AND they wanted Andy too as he is brilliant! Andy has spoken about the incompatibilities between the old 1500 stuff vs Nexxus, and it totally makes sense. It's not JUST software that is different, there is huge changes in the underlying hardware too. It's why Haltech has had soooo many changes in the last couple of years, in terms of Hardware, and Software, and why it has become so damn Amazing. Why do you think guys like Rob Dahm with his quad rotor, went from running Adaptronic's to running Haltechs? Andy. Pretty much, Haltech these days, is Adaptronic, but with more funds behind it, and more staff, and hence Andy's visions, and visions of other people that he helps shape their great visions, into amazing new products. All the new Nexxus gear, whole new software for it, new and better dashboards, the apps that will run on headunits and NOT be slow to respond! I understand people being burnt in the past, but if you're ragging on a company, about products and issues from many years ago, it's more a reflection on yourself, not looking or keeping up with new stuff. In which case, those people should be going back to PowerFC and Nistunes as the ECU's to rave on about...

      Right, but I thought the problem has been for a while now that even if you know manifold pressure + throttle position you still have non-linearity and aliasing issues vs actual engine load? One way I can see things simplifying is going DBW, then all air going into the engine is represented by the throttle position. As opposed to a random bimetallic strip vaguely linked to engine temperature opening and closing a shutter or some random power steering air valve suddenly allowing a bunch of bypass air. But the same throttle position/RPM at ~atmospheric MAP in different gears is not guaranteed to be same engine load? Honestly, ITBs are of such dubious value IMO. I don't know why these things are hyped up so much. The main benefit as far as I can tell is you reduce the likelihood of cross-cylinder EGR scavenging with significant cam overlap at idle. I would absolutely run speed density and be done with it if not for this fairly esoteric control problem.

      Alarm/immobiliser recomendations for an R33

      By PotatoCake · Posted

      Hah dont worry, my adult brain has this conversation every single day. Dont waste your money, invest more of it into shares, pay down the mortgage. Then the bedtime insta doom scrolling begins and after being bombarded with gtr's my mind is set: im definitely getting one! I have the current model mx5 as the weekender, but i just miss my boost and literally like your username, the sututu's that come with it. I remember with my 2nd supra, as it had twins and vvti, they used to spool real early, like 1,500rpm so you could just be a spooly boy all day long. Some people say they get over it after a while, not me tho.
