My turbo is broke it appears (makes a funny noise and no boost pressure apparent) and I've had car only a short while. I forgot to change air filter when I bought and it turns out to be filthy. Whether this is the cause or not I am told by a turbo reconditioner that it is a possible cause.

Nissan here in Rotorua (NZ) don't have any experience of this model and are suggesting an engine out in order to remove situation which will prove drastic to my finances.

Has anyone here got any idea of an easier way of removing the turbo for inspection purposes?

it should be possible to remove it without taking it out of the car.

the high pitched whistle.. have you had it re-cornfirmed by someone that it IS the turbo ?

some cheap intercoolers give you that " china whistle "

just saw the comment about no boost pressure.. could be split hose?

remove the pipe inlet and have a look with a mirror if necessary, removval of the rear dump will do thesame.

problem is access to bolts at front on turbo is proving impossible in order to remove it

no high pitched whistle but an impotent sounding arrrr type sound and no pressure

problem developed over weekend I was up Mt Ruapehu and it was sounding rough on mountain road when I backed off the accelerator

got back to Rotorua and it packed up on Sunday

also the car refused to start at end of day up on the mountain and I had to roll all the way back down to Ohakune

17 km's downhill all the way

I'm wondering if trouble with turbos convinced Nissan to go NA back in '04

Hmmn.. I'm still unconvinced it's a turbo failure, pretty unusual in a new car like this - Like suggested before, first thing would be to pull inlet & exhaust off it and have a good look at it, spin it if you can. Does it blow any smoke under boost or when cold? I'm sure you can remove it with the engine in car. Even in my 300zx TT which if anyone has ever owned one, you can't even SEE the turbos under the engine bay, are possible to remove with the engine in place. Fair enough it's easier sometimes to drag the engine to give yourself more room, but maybe source a service manual for the M35 and read the Nissan procedure.

Anyone know what sort of snail these V6 engines use?

Does your car blow any smole at all after it warms up? Black smoke you will need only a tune up. If white smoke then the turbo is buggered. Wgen you step on it does it give a black puff of smokes at the back of the car?

If your car is stock standard it is very unlikely for the turbo to be shagged. Also check the manifols whether there are any signs og oil seeping on the manifols itselfs.

If all else fails get it into a worskshop that is familiar with nissan engine.

No smoke at all that I can see

The air filter was filthy and may have been OEM

I'm told by turbo experts here that this is a possible cause of turbo failure

That little Jap girl's voice in my car seems to pick up on an emptying fuel tank (and so does the screen) so why not cry out for more air?

So far I have paid $NZ 600 to have a $30 air filter replaced that I could do myself. Better than forking out 5 grand unnecessarily though.

It drove me back to Auckland alright yesterday and the gas consumption is improved (9.6 km's/l, 500 km's on less than 3/4 of a tank) but that may be down to my just having to lay off the thrills.

I will seek out some experts here this week and maybe Nissan Japan and keep you posted.

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
