Ow, yesterday my plugs were running a bit crap after my mate had borrowed the GTR, so I took it for a run up Mt beachmont, set the boost to limit at 1.2 bar as usual, and part way up the hill

*BANG* the loudest what i thought was a backfire went off, but came from the front, the car was still runnning good, but as soon as i slowed down enough to use the 3-4rpm range it started running very rough so i assumed my plugs were just fowled a little more, anyway got home and discovered the pipe that takes air from the turbos and feeds it to the intercool had blown itself open! about a 270 degress split around it, the material reenforcement the only then that stopped it seperating further, anyway check the boost controller after and the highest i got it too was 1.19 bar, i have been up to 1.28 before.

crazy stuff, fortuantally the boys at nizzpro had one lying around i could swap it with, then some petrol and a toothbrush to attack the plugs it like new again...

The day i tuned the car to 30psi i did not give a bit untill that night, first time i floored it i heard this massive bang sounded like it came from the front and the back and under the car, then the car started running like crap.

It blew 2 intercooler hoses off (one off the turbo and one on the other side of the car near the intercooler) and broke 2 hose clamps.

Scared the shit out of me. i seriously thought i blew the engine up lol

I've done that on 14 pounds lol. About a week after my FMIC went on, those cheap shitty hose clamps snapped and blew the alloy pipe out of the silcon joiner. Scared the shit outa me, thought i cracked the block or head or something haha.

haha who did you lend it to?

I'll give him the bash next time your over or i'm over

andrew del was driving it

i always lend my GTR out, while i have no license it keeps it being used

yeah i have had tons of pipes blow off, the stock clamps are crap, i replaced them with some huge non worm style ones, about $5 ea but worth it, if you do them up too tight they crush the thin metal tho

    • So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?
    • I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
    • Stop looking at the garage floor, and turn the radio up a bit louder if there's any strange noises...
    • No. Turbo shuffle and surge/flutter are not the same thing. Specifically, on a GTR, turbo shuffle has a definite meaning. On a GTR, the twin turbos are assumed to be the same thing and to operate the same way, exactly. In reality, they do not. Their exhaust sides are fed and exhaust a little differently, to each other. Their inlet sides are fed and exhausted a little differently, to each other. Consequently, when they are "working" they are often at slightly different points on the compressor map compared to each other. What this means, particularly when coming on boost, is that one of them will spool up and start producing extra flow compared to the other, which will put back pressure on that other compressor, which will push the operating point on that other compressor up (vertically). This will generally result in it bumping up against the surge line on the map, but even if it doesn't, it upsets the compressor and you get this surging shuffle back and forth between them That is "turbo shuffle" on a GTR. It is related to other flutter effects heard on other turbo systems, but it is a particular feature of the somewhat crappy outlet piping arrangement on RB26s. There are plenty of mods that have been attempted with varying levels of success. People have ground out and/or welded more material into the twin turbo pipe to try to prevent it. Extending the divider inside it works, removing material doesn't. There are aftermarket replacement twin turbo pipes available, and these exist pretty mush purely because of this shuffle problem.
    • You can temporarily* use lock collars to keep it in place until you can do the bushes, back the nuts off, slide them in, snug back up. *temporarily is often for ever
