hey all... ive been putting off doing this since i got the 260, i need to fix a leek problem i have sumwhere around the rear turbo... im hoping its the turbo to dump gasket... just dont wona have to pull HEAPS of stuff out.... is there any way to ultimatly locate the drama b4 pulling it apart... i know its to do with the rear turbo, its that usual thudding/puffing sound.

i got my 100k done at a reputable workshop here in adelaide. and they said its the turbo to manifold gasket... how would they tell by looking?? or is this a yeah he wont know its just the dump.... 1 hrs work $900 thanx for coming?? ill pull the heat sheilds off thursday and go from there

im guesing if it is that turbo-manifold gasket i just need a 33 gtr one?? and ill need to do both at the same time yes?

thanx :P

get yourself a short length of garden hose and hold one end to your ear while the car is running. move the other end around the area you 'suspect' the leak to be and you'll be able to hear it clearly ;)

i remember your car sounding a little tractor like off boost, what's it sound like on boost? any loud banshee-like squealing?

do you have a boost guage fitted? if you do, what happens to the reading when you're on boost etc

just realised you're on msn... will continue there :P

I spoke with a couple of friends at AJD regarding your exhaust leak issue, and the new wasn't good!

From a labour perspective, it seems that getting to the rear turbo means pretty much removing the front one.

However, removing the intake & shielding should help reveal the source of the leak - they will squeal like crazy on the intake side of the turbine, from memory your car sounded more like a head/manifold leak (i.e. a tractor)

Keep us posted Adam...

Mine went that way. I bought another turbo but when I pulled it down it was broken manifold studs. Bugger of a job but got studs out without taking head off.

If you do find broken studs, a fairly common RB issue, look in local Yellow Pages under nut/bolt suppliers and ask if they know of a mobile stud fixer. I was lucky one lives here on Tamborine and it was $100 to get four removed.

alrity... well tomorrow im gna rip it all apart and have a good look... im kinda thinking its exhaust to turbo gasket... theres no hi pitches squeel... it still hits resnobal boost :S so is there any thing really to sugest other wise? guess no1 can tell till i look :)

ben, thanx for that bit of info, im hoping its not bolts or sum hard to get gasket lol...

      How do you go about diagnosing ecu's that don't have data logging, is it more experience at that point and just trying out things that you think will fix the issue?

      Stock O2 are basically useless beyond anything at stoich. Any misfire will also be seen as lean. The stock O2 also read a collective exhaust gas volume, not each cylinder. Sputtering and missing means not each cycle is firing, and some are. Which means even if rich, as shit, on cylinders as they miss, they'll read lean, but the cylinders that did fire will read rich, and combined, well, they can read anything from rich to lean.   Start with the basics before even going looking at sensor values.   Edit: I say the above, and that's coming from the guy with a few thousand dollars worth of scan tools sitting right beside me right now that I use frequently for my job.

      I just finished up a manual swap and I have a 1999 S2 AWD automatic in my garage, depending on where you are located. I'm in the the midwest of the US.

      R33 GTR N1 REO on an r32 ?

      I’ve heard it can be done, you need to redrill the holes where they bolt to the chassis and apart from that they are the same. I’ve never done it or know anyone personally that has, it’s just something I’ve heard

      If it's reading full rich prior to a misfire that gives one directional hint, if it's already reading lean, etc. If it's reading pretty cleanly stoichiometric then suddenly drops out from a misfire that suggests it's not air mass estimation that's the problem. Could be ignition, could be something more subtle. Could be the CAS has decided to start dropping out at random or the drive pin is worn leading to excessive lash and trigger errors. LTFT can tell you the same but it's slower to react and if this is a recent issue it might not have stabilized. STFT stuck in one direction vs fluctuating back and forth can be used instead but I like to read O2 voltages anyways and interpret directly. If the O2 voltages make no sense in general or are super slow to react it could also be a failing O2 sensor. There's no real error correction for failing O2 sensors in these cars.
