Turbo failure?

Hey guys i have an R32 GTR and i have no boost anymore. Not long ago the car just stopped making any boost. I was on boost at the time. There was no loud noise, and now the car runs smoothly and fine it just never comes onto boost (always below 0 on the boost guage)... Before this happened i think it may have been an intermittant problem...

I have checked out the stock recirculation valves and even if i block them both off there is no change. I thought perhaps they were leaking and continously recirculating. I also looked over the whole wastegate actuator setup, from where the vaccum signal is picked up off the intake to the turbo, to the boost solinoid and back across to the actuators themselves. It all functions properly and smoothly..So now im dreading the fact it could be a turbo failure.

Basically i want some ppl to tell me wat happened when they're gtr's had a turbo failure. Was there any noise? How did the car run after? Was it running like mine is?

Thanks heaps,

Deren

When mine let go I was giving it a hit up a hill, backed off at the top of the hill, then back on the throttle going down the hill. The only difference was going up the hill I had boost, coming down the hill I didnt. It didnt make any noise, nothing, just no more boost... checked my rearvision mirror and saw the dreaded smoke screen as well and knew a turbo had failed.

If you have checked everything and theres no leaks etc, then I would be leaning towards turbo failure. Remove the intake pipes and see if any have substantial amounts of oil in them.

Thanks for that, I will check that. The thing is its not blowing any smoke... I plan on getting it diagnosed by someone. Not qualified yet :wassup:

      High temp brake fluid?

      By Murray_Calavera · Posted

      Just checking, when we are talking about high temp fluid, are we all referring to DOT 5.1? I haven't had any issues with changing it every 2-3 years.

      Yeah that is still true AFAIK.....good brake fluid should be changed annually because it absorbs water faster which is more often than most mechanics would do it. There are cheap tools that check water% in brake fluid if you all scientific about it. I for sure would (do) run good brake fluid in anything that even casually saw the track like Murray said; avoiding the risk of "exciting" fade is worth it

      Well, back in the day..... "race" fluids, which were essentially only really "high temp" fluids, used to absorb water more readily. So they really needed to be changed more often anyway. The coincidence of that being directly necessary along with it being what racers would do as a matter of course was just fine.

      Does the high temp fluid degrade any different over time compared to normal one? That's one thing I've always been wondering. Because a track car is going to get the fluid flushed probably way more often than every two years and will see less kilometers driven. I would think the requirements are different. I'm running Motul RBF 600 in mine. Was recommended by my mechanic before a trackday and I've stuck with it since. Hasn't seen the track since but I've kept buying and using it for servicing anyway.

      The brakes are all stock bar some DBA slotted discs and the EBC pads and braided lines. The car has brake ducts as standard but they're kinda pointed in the general direction of the brakes rather than really getting at the heat source. I guess I should hit it with an infra red thermometer after a session and see what they're at.  100%! Its just a curiosity more than anything. As I said, high temp brake fluid was such a track day rage back in the day. From people I speak to at the track and threads on here everybody has their own take on it but I'm not gonna scoff at spending a few more bucks.    OH, a quick side question - would you use brake fluid from an opened container even if the lid has been on? Eg, if you have a bottle that you opened last time you flushed, it's been tightly closed, is it still good?
