Turbos Not Working On My Gtr 32

The car is a completely standard 1990 GTR 32, standard boost, standard airbox and exhaust as well.

It was ok when I left home this morning. When I was on the way back home on freeway, suddenly a strange sound came out from engine bay, then the engine lost power and felt like a NA engine.

I tried to push it hard, the REV went up slowly and didn't feel the turbo power, the boost guage never went past zero, a winding sound came out from engine bay and the sound became stronger when the REV was higher.

When I got home, the car was idling as normal, no smoke came out from the exhaust, but still no turbo power.

Can anyone tell me are the turbos gone or is the engine problem? I didn't feel either of turbos is working. Is that expensive to fix? I hope it is not a serious problem.............................

Any help will be appreciated in deep.

The turbo is most liekly blown. When the turbo blows, it doens't have to blow smoke. I have one here without a rear wheel that didn't leak a drop of smoke.

Could be expensive if the ceramic dust went back up into your engine taking the engine with it.

If not, you're up for a set of turbos, plus the labour

What where you doing when the noise " suddenly " started ( fullboost or just crusing ).

Sounds something like what happened to me, when i left home one day the car was running fine and the further i got the less boost i had till i had none at all and same as you i thought i'd blowin a turbo but the day i drove the car and it had boost again and again the longer i drove it the less boost i had til it was all gone, turns out it was the compiance cat that came with the car had stuffed up changed it and had no more probs. :P

So how do I know the turbo is blown or not? I don't feel the turbo power at all, I thought if one of them is blown, the other one is still working.........can anyone give me the answer?

And what is the reason why the boost guage never goes past zero?

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
