R32 GTR... HELP ME!!!!!!!!!!!

Power stearing GONE. Driving along, heard some funny missing noise, sounded like i was in a WRX for a second, then it was all good again. Pull up, realise there is no power stearing. Remove the shattered belt remains.

Keep driving for a bit without power steering, suddenly, no more spool! AT ALL!!!!!

Nothing, turbos are NOT spooling! Engine sounds fine, cooler pipes seem in tact.

Just got car off defect, now this...

You guys go right ahead and write back, I'm going to go cry somewhere... :Bang:

F#@KING PIECE OF S#&T NISSAN F#@KING SKY_F#@kING_LINE... I hate it! I hate it!!!! :)

I don't know but I don't believe in coincidence. Could the ecu detect the power steering loss

and go into a limp home mode?

Thanx sooo much for writing back.

I was hoping the same thing. Two things that back our theory up

#no sh#t loads of smoke

#drives really well with no strange noises... just plain doesn't get over zero on boost gauge and feels like this is the case.

doesn't reset after turning car off tho... maybe i have to fix power steer first...

how would it achieve such a limit? just like a rev limit, but using the air passing thru the AFM to say stop right there buster

:: EDIT

i didnt quite see you mention GTR.. so my response to your no spooling of maybe your exhaust wheel went down your pipe would seem to be quite wrong since you have TWO turbos and its unlikely they both went..

pardon me.. ill be on my way..

shaun.

OK OK, now this has elevated status to critical.

Replaced the power steering pumps belt today and power steering is back better than ever....

NO TURBO'S!!! NONE. Car is very drivable, sounds a little weird when it would normally be boosting, but besides that, drives pretty normal.

Am going over to reset ECU now... been checking for signs of leak from cooler piping... nothin'

Am a nervous kid. :)

Reset the ECU. No change.

It's like the turbos aren't even there. They make no attempt to spool. There is no noise at all from them. There is possibly more noise going on under the tappet cover than normal. Thats the only difference in noise.

HELP HELP!

Some of you guys must have some idea...

i had a similar problem, no spool after a back fire. found out the new cooler i had fitted on the left hand side the cooler pipe had blown of but the pipe was still inside the hose so was hard to locate boost leak. it worked out that there was no bead welded onto cooler pipe to stop hose clamp slipping of. my car lost all boost and also sounded like a wrx just before the hose came off completly. before this problem was detected i had the induction piping to turbo of to check that turbo was still spinning when engine was idleing, which it was because i thought i had blown exhaust wheel off!! hope this helps you.

This may seem silly but are you actually driving the car?

My car won't boost without load, so free revving it on the spot won't go over 0 psi.... this is my first turbo car and when it happened to me I freaked out too heh.

Good luck, I hope this it :)

Haha, yes. I noticed it while driving.

Although boost doesn't go much over 0psi with no load, you can normally here the turbos, but at the moment NOTHING.

I was thinking maybe actuators were stuck open, so tryed to drive it up and down the street a bit on varying loads to maybe unstick them (foolish plan I know). It would be strange they would both go at once.

I reckon its gotta be that too hey. Just be screwed if I can find it.

I was certain it was the top pipe off the inlet of the turbos. cause I had just taken it off to attend to the power steering pump. So when it went, I was like, I know EXACTLY what that is... then I pulled over, and its fine....

I guess I should just go check ALL of the pipe work... it would be weird if one blew off besides the one I was messing with....

yeah, thats the thing. I was actually taking it for a test drive with the belt off, to see if it was ok to drive with out power steering. so when it went, the belt was already out of the car, i wasn't going nuts... everything was normal.

I have just checked the pipes again... its hopeless.... nothing...

thanx heaps for the ideas guys... i'm just useless.... *crys*

Don't know how hard it is on the Gtr but you may have to take the dump pipe/s off to see if you still have exhaust wheels on the end of your turbos.

You would think you would hear a boost leak if some of the plumbing got taken out by the belt but if everything looks right then I'd be thinking turbos.

yeah, i was thinking it might be somewhere there as i can't see anything wrong with the actual intercooler piping...

but i couldn't get to the bov pipework... its on the passenger side down low isn't it? i can't even work out where the bov is...

how do i get to it to check it?? looks like i'll have to take off the front bar...

On a related note, what should one replace the hoses to the BOVs, actuators, etc with? Silicon hose, braided lines (bit OTT?), or just go with new stock jobbies? I'm tempted by the silicon hose as there seems to be a lot of it around at the moment.

Would have to be a pretty big leak for it to make 0psi on full load.. and you would certainly hear it.

I have had intercooler pipe leaks on GTR's before, even small ones made a large sound but I only lost a small amount of boost. The turbo's just worked harder. :(

You would also be very unlucky for both turbo's to fail at the same time.. very!

You must have a whole intercooler pipe off.. I would take the front bar off and have a really good look.

      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

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
