If you go 2.8, you're going to want bigger turbos. Scratch that. If you go 2.8, you're going to want one single larger turbo.

Yuh. It is very rare for a single turbo to throw ceramic into the engine. Quite common on GTRs. As I posted above. Mine did destroy the O2 sensor on the way out though! Plastic compressor is fine with the temperature. It's not some flimsy PE/PET/PP thermoplastic. It's a thermoset resin with reinforcing material in it (a composite, as posted by @Lithium above). The compressor never sees much more than 100°C because it's never boosting very high. If you boost it high enough to make a lot of temperature, then the turbine will depart the scene and stop the party anyway.

Yes, but it's not as easy as pulling a fuse on anything other than an R32. There's a routine you have to do, involving disconnecting a loom plug and bleeding down the preload.

Son, in this country, that is a piece of Gyprock. f**king drywall. FFS! I also like the autocorrect of trailer to tablet. I was reading it and thing, "what the hell drugs is he on?" Then the photo made it clear enough.

As @Duncan said - the bores are most likely to cop it. But anything can and does happen. Rods are cheap. Rods are good. The work to rebuild the motor will be 30x the price of rods. You won't notice it.

Yes.

Hi Tao, It seems that turbine fragments entering the engine is more of a thing with the twins. The theory is that because there is much more of a straight shot from the turbine housing directly at exhaust ports, they seem to cop it where the single turbo cars don't do it so often. It is definitely something that we hear about on GTRs far far more often than the others.

My Neo turbo only went last year. Not 35 years old, to be sure - closer to 25. But still.

What's the difference? I would have said that between the front and rear axle lines, there's no noticeable diff between a GTR and an NA 2-door.

It will be salvageable. It really doesn't matter what is damaged. Opening up a 30+ year old motor for a rebuild immediately means a complete rebuild of the head anyway. Damaged valves just means an opportunity to put in some nice new ones. And in the modern day, why would you not throw at least a nice set of pistons at something. And if you're doing that, why not rods, and ARP fasteners, and so on.

They usually get made by hand as part of any such swap.

Yes, at least 10 years before anyone ever thought of making such a panel. Of course.

Um. No. Since Matt introduced the TIM it has become a lot easier to deal with the consequences of changing K for AFM and injector swaps. Then, tuning is a f**king doddle. No-one needs to know or care how many grams of air are flowing or any other bullshit. Need more fuel in a cell? Add more fuel. Need more timing in a cell. Add more timing. Need to adjust any of the other tables for warm up and so on? No harder than anything else. Sure - it's not an ECU system for starting from scratch on an arbitrary engine. But then.....it was never supposed to be, not recommended for, and almost never used that way. So.... On your engine, in particular, Nistune/Nissan OEM is about as sophisticated and difficult as banging 2 rocks together. Those ECUs are primitive and simple. There is nothing difficult there. I learnt Nistune from scratch, created new maps with extended axes, interpolated/extrapolated the original maps onto them and tuned my RB20 (basically the same ECU as your 26 ECU) all by myself, more than 20 years ago. And that was long before even TIM.

So common, it's a meme.

Note I edited my post, so Sleeper's quote is not the same as what I meant any more.

That's a whole 'nother issue. Nissan ones get dirty and sticky. The coolant heats the wax pellet thingo to close the valve, so it is open when it is cold. And so if there is no coolant it just takes longer to close, because the heat has to soak all the through the inlet manifold.

Because they are annoying and sound like arse with the revs flaring all over the place when they are unlocked.

Not that anyone in most of Oz would notice if there wasn't coolant flow. When I bought my Neo, that whole coolant path was completely blocked with solid crap. I had to dig it out so that I could bleed the cooling system properly, but until I did, I never struggled with idle control. We're not in Idaho.

Yeah. One on the back end of the plenum, on the IACV, and one on the front end of the plenum. They are both plainly visible.

According to the Muse website, totally different material. The originals were that horrible solid foam rubber that was used for a lot of rear spoiler/flap things, like on Mitsu Galan GSRs. Heavy, and with enough compressibility/flex that any paint on them would crack fairly quickly. The Muse ones are just ABS, which is obviously similar to GTR lower front lip, etc etc. ABS is a good choice if you have the ability to tool up for it. The only thing better might be TPU-RIM PUR-RIM or something equivalent. The TPUs PURs were good. Plenty of flexibility (in twisting, bending, etc) but not really in compression. --edit-- Bloody talking bullshit. TPU wasn't a thing back then. I've been afflicted by 3D-printing-itis. I mean PUR. PUR-RIM is Polyurethane- Reaction Injection Moulding, which was all the range back then.

It's a valid thought. There's not exactly that functionality already (when creating a thread) - that's where the OP can use/create any tag they want. We'd have to come up with a way for the user to request their tags get reviewed or something. Otherwise the mods would have to review every new post's tags (for those that have them, anyway). There's kind of that functionality already exists to some extent, post facto of starting the thread, where the OP or any other user could report the post to admins, and request that tags get reviewed. We could do this already, and any user could already have made such a request. To make it a part of the forum proper, it would require an initial and an ongoing education programme, so that people know that it's a thing. OP based tagging/request for review would also require at least some (probably most) of the user base to be told that it's a thing they can do. Both of these things probably wouldn't spread too far and/or get used very much. If it was the standard approach on a lot of different sites, then it might do, because people would be used to it. Prank's approach to this differs from my original thought, by leaning into tagging. Which is fine - it's possibly better than what I originally suggested. In fact, I just went to the R32 GTR wiring diagram thread and added tags, including "Library". That's probably a good way to use tags and the idea of a library. We just have to drag together an (organised!) index of threads or posts that have that tag. I have yet to do any of my own follow up by pursuing worthy threads and posts and reporting/marking/tagging them for the library, such as the @Sydneykid stuff I was talking about, and possibly any amount of @Lithium 's and others' posts. At least if I tag them Library, we'll have a start. Back to @Wazmond's idea as it relates to @PranK's, we might have some sort of a list of tags that are already used to scrape for this library. I'm not entirely sure how that would be presented or used, particularly if it got long. But it's yet another idea! cheers

Yes, a plan for non-action is always my first sort of plan! I'm happy to see what falls out of invision's update. I had been having some thoughts on what to do with this the other day and they all seem to have fled my memory, after various solar panel induced traumas, squeaking suspension sphericals, etc etc, over the last little bit. I'll try and recall what I had in mind and make sure that I put it into print in some form before the Alzheimer's strikes again.

Nah, you failed to pay your washer cover subscription and BMW have revoked your access.

f**kin' yikes! That insulation is the shittest stuff I have ever seen. You need to do an insurance job on that f**ker, pronto. WRT to the washer cover, I would have said that there'd have to be some at a wrecker, then remembered that it's a BMW, and reasoned that every single wrecked one would have been tailgating and so the front end would be trashed.

Yeah, I wasn't giving two f**ks for the ring running around the bore. I was looking at the vertical scratches running up and down across the hatch marks.
