as the title says its a turbonetics 850 turbo, with less than 5000kms on it, and currently only 18psi...

it only seems to blow blue smoke if I start it with in 0-20 minutes of turning it off, while everything is still warm,, if its been sitting for an hour or two or over night it doesn't, and don't think its blowing any on normal driving or under boost, does this sound like turbo seal?? I'm thinking its turbo seal because when its cold then the exhaust is'nt hot enough to burn off what little oil has leaked out straight away, and maybe just burnds it off slowly as it warms up without me noticing, ???

if it was valve stems leaking I would expect it to smoke in the morning and after an hour or two when cold as well ??

You need to check your oil drain setup if it was doing that from the date you installed it. Also check to ensure your engine is not overfilled with oil.

Else check turbo for back n forward and side to side shaft play. Excessive play mean worn bearings (and seals) due to oil starvation or contamination. If that is the case ring up your supplier for support and repairs.

thanks Stao, no wasn't like that from install, just started, and engine isn't overfill..

to check shaft play, is it as simple as pulling off the pipe off the front of the turbo that goes to the intercooler, and check for shaft play in there, or is it turbo out job ?

wouldn't have thought oil starvation, its got a Jun oil pump which sits at 4 bar even at idle ( well 4 on the standard oil pressure gauge, not sure if thats bar ) but you agree its likely to be turbo rather than engine ?

Well the restrictor is on stock oil feeding line. If its not drilled out then that might be a problem. Also is this the Ceramic BB units? If the wheels and shafts are in re-useable condition it shouldn't be too expansive to repair, other wise it could be very costly.

Its best to speak/email to your supplier or manufacture for support, they should be able to assist you on repair.

thanks again

Its a GTK-850 ( ceramic BB ?? ) I'll have to find out from the engine builder if he drilled out the oil feed.. I take it from what you are saying the standard size feed line is inadequate for this turbo ? it was running 24psi @ 760hp at the motor..

I'll have to find out where it was purchased,, I bought this setup immediately after it was finished, now to sort out the gremlins

cheers

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
