Ok, Heres my problem.

Today (Boxing Day) I started my car and took off fairly hard bringing first gear up to about 6000, I then proceeded to change to 2nd hoping for that nice wheel spin can be achieved from this. Alas I was not greeted with wheel spin but a great loss of power like bad turbo lag instead.

Now to my problem, ever since this every time I get the revs to 3000 in any gear from 2nd up, the revs suddenly jump to 4500 and then back to 3000.

There is no jolt when this happens, just an over revving laggy engine.

Also there is now a slight ticking noise coming from under the left hand side of the bonnet when the car is idling.

I am thinking that it could possibly be a blown turbo gasket? But it has all happened so suddenly after me being stupid and not allowing my car to warm up correctly.

Could this be the cause, What are everyones thoughts?

BTW my car is stock except a 3in cat back.

Any help is greatly appreciated as I am fairly new to the world of turbo cars, and my mechanical knowledge of cars in general isn't exactly in depth, so go easy on a newby

Ticking sound from the around the turbo certainly sounds like a blown turbo gasket, I had similar problem a while back.

If it is, its not an expensive fix.

Poke your head in the pasenger side of the engine, you may be able to see the problem.

Dont go flogging it, cause if its the gasket you dont want more pieces of the gasket breaking off and flowing through the various parts of your engine.

Thanks mate. What exactly am i looking for with a blown gasket. As I said I am a complete newby to the world of turbos, but I am doing my best to learn about them.

I know where the turbo is located but what exactly would the blown gasket look like?

Any help is greatly appreciated, as none of the mechanics in my area that I would trust to work on my car are open due to the holidays.

Thanks in advance.

Sounds like it could be a slipping clutch to me?

Trying to decipher your problem as a couple of the other guys have stated it does sound like it could be your cluth that is the problem.

But just to clarify something for you you say it feels like and over-revving LAGGY engine

Over-revving does indicate slipping clutch ( you can check this by loading the engine in a higher gear at relatively lower speeds) caution though be careful not to do to much damage

Lag is the lack of REV's or "pick up" when you accelerate theoritically opposite ends of the spectrum.

but anyway good luck.

thanks for all the replies everybody (and for the definition of laggy).

Sorry for the late reply computer problems, it never ends!

As it turns out the clutch was the problem, took it to autosport and they had it diagnosed about 2 seconds after getting into the car.

Anyway, it is now replaced with a heavy duty item and is going better than when I first bought it. It is even creating up to 10 psi boost (only could get 7 before new clutch).

So in summary thanks for the help, and these forums have now become my official home away from home. Such a wealth of valuable information!

cheers

      Rv37 400r questions

      By sonicii · Posted

      No idea about the remote start part. If the V37 nav is anything like other Nissan JDM vehicles, you can't get the factory Japanese nav working in australia, a card from a different car almost certainly won't work, those cards are usually matched to the serial number of the DCU.  You could be possibly swap out the components from a AuDM Q50 to get it working, but if this is a new model (2021+) 400R, then you will lose the newer features like ACP/AA.  That said, if you have ACP/AA, just use google maps.. I assume a band expander would be required to get the local radio stations, but don't forget the Japanese FM band is narrower than ours, so you still might not be able to receive all Australian stations. I can't see any reason the tyre pressure sensors won't work here, there is the sensor unit inside the rim and the receiver nearby in the wheel well.  I have never had to change the batteries on my 2015 Q50, so I assume they last quite a while.  A straight battery change shouldn't need them to be re-registered as they are the same unit, that should only be required if you replace a sensor with a new one.   Word of warning, if you ever go into the 'secret' diagnostics mode on the main screen, DO NOT EVER do a 'reset' in this menu, it will erase all of your model specific data in the DCU and you will need a trip to a dealer to re-program it all, which would be particularly painful being an import.  This applies to the AuDM Q50 too.

      There is a known issue with the mix door motor on the Q50 which causes these symptoms, not sure if it is common on the Y51 though.

      Rv37 400r questions

      By elir32 · Posted

      Hey guys. I have a 400R on its way to Australia from Japan currently and have a few questions I’m hoping others may be able to help with.   Wondering if anyone here has had any luck getting the Sat nav unit to work in Australia!? Assuming the Stereo is as simple as a band expanded and tv won’t work?  Seeing as they’re based off a Q50 which is Aus delivered is there any way to link that system to the nav? Nav modules and head unit are different part numbers and appear slightly different at the rear with plug ins etc. can I put my xtrail sd card into the rv37 and will that convert the maps or update to Australian? Has anyone got any advice here?     also has anyone fitted the factory remote start and Security system once it’s landed in Australia? I put an enquirey to Nissan Japan in via a third party, and they suggested it needs a Nissan Japan dealers device to setup and couldn’t guarantee if one here could do it or not. They can supply and I can physically fit it but to setup I would need a dealers device. Any information here would be appreciated also. I’ve seen one here with it fitted already prior to leaving Japan at a dealer/inporter, so clearly passes compliance and works when fitted Japan and doesn’t need changing here.      also, does the tyre inflation sensors work here? Does anything change with them when the vehicle arrives? Where are they actually situated? I’ve read they have batteries and they need to changing at times and seems like resetting involves the nav system?    any help here would be appreciated and any other aust specific information to help would be great. Looking forward to see what the current generation skyline is like and eager to see how many of the gadgets can be utilised here.  Thanks in advance

      Do need to take it with a pinch of salt. One of the adapter failures, they clearly had setup issues with the flywheel.  One of the slipping ones I spoke to and it was pretty clear the throwout was riding, rather than fix, just swapped to a new clutch.    These clutches are being put in anything from 5k offroad 4x4 beaters, GR yaris, 500hp commodores to 1200hp barra monsters. Bound to be some issues in some of them when they are not a simple bolt in affair due to the changes in height.    There is a lot going on in this picture and unless I did the job myself no way to tell what really happened.
