i was thinking , an rb26 being twin turbo, if one turbo was a bit worn and not spooling as fast or as much psi as the other , could that not cause some sort of unbalanced motor and put extra force on one end of the motor??:whistling:

and if the compression was a bit up and down and even the weight of the pistons,rods,etc was different all that put together could cause a spun bearing couldnt it?? does an rb26 have two boost guages??:mellow:

simple answer? no.

Is glittery oil normal after a fresh engine rebuild. I just rebuilt my motor and im hearing a noise as weel from cylinders 5 and 6. Sounds like more of a top end noise with the stethescope but im curious about the glittery oil during the break in period. Looks like a goldish color.....

Gold is generally a bad sign as it is often the seconf layer of material on bearings... that said it could be numerous things.

Oil analysis is the best bet or change the oil out now and recheck it down the track... there should be minimal shavings in any motor (even after fresh build, as it should have been thoroughly cleaned to start with) its like circulating sand... bad.

Nowadays there is far less run in material in the oil in a first oil change due to better equipment and tolerances being used.

    • I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k . 
    • Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?   
    • Yeah I've spotted this one too, whenever it's lotto superdraw week and I'm browsing car sales dot com for my new ride They must be dreaming, maybe it's worth 150k for the link to Brock?
    • 100% accurate!  We are a pack of know it alls....  But, I bet people go to you when they have a problem! I've been on a bit of a clean up rampage too over the past month!  I've thrown more shit in the bin over the past 2 weeks than I have in the past 3 years combined! Anyway, it's all good fun being different! My wife sometimes does not agree!  
    • ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
