I've got a t04e(i think or something near to that) on the side of my RB25.

Last night the turbo just started to whine really loud like a blender with nothing in it. The whine was reasonably high pitched and started when i reached 5000rpm.

The car hits the 13psi it's set to at 4300rpm so when it hits 5000 it's only just making all it's power... but it doesn't have any power at all now.

My Turbo is usually very quiet and i cant hear it at all when on boost. Only the sucking of air and the exhaust so it was noticable straight away that something is a miss.

Any ideas what could be wrong with either the car that's making the turbo whine, or is it the turbo itself?

We checked all the cooler hoses and the intake pipe (mine is metal) is still on.

I've got and ARC cooler.

Thanks guys!

mmm... im thinking it is.

but could something else making it do it ???? (unlikely i know)

BTW anyone know how much a rebuild should cost ?

But then, i can get it 'tinkered' with too while it's off... and get some more out of it, this situation might not be all bad

one other thing.

My RB20 turbo was making a noise.

It turned out to be the gasket between the turbo and the manifold (on the block)

it seems that one of my bolts had fallen off and the heat at that corner started to burn out the gasket and eventially melt it and air was escaping through there and whining it's head off.

turbo was in perfect condition.

But if yours has a lot of thrust play (as in back and forth in to the turbo, not side to side), then you may have issues..

Although, a little play is normal.

If it is a gasket, it will set you back less than $50 for the gaskets and who knows how much to pull the turbo off and replace the gasket.

R31Nismoid, if you have to pull the turbo off, you can do it yourself. I've done a how-to in the Maintenance section, do a search. And since I've also got a T04E, you will probably be able to follow it word for word :(

my car done the same thing today.. sh*t my self.. stupid stocko bov caused it.. took it off and blocked up the whole and its all sweet.. check everything else before you go taking it off and getting it rebuilt.. could be a gasket? or a stuffed bov.. :(.. it was a wheezing noise when boost came on?

mmm... it's gotta come off now..

GRRR... god damit.

benny @ BMT says a bearing. and it's probably hitting the housing (hence the noise) so i could be up for mroe than a standard re-build...

me thinks a bigger housing :(

Have u made sure its not the obviouse though?

wouldnt want to be up for the cost of a rebuild only to find out it was a leaky gasket

make sure it gets proven to you that it is the bearing when the turbo is all off

i recently replaced my turbo with an aftermarket item...it was suprisingly easy to do :S

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)

      Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.

      Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
