Hi All

Two months ago i purchased a 1999 S2 RS Four S

When my car comes on boost and holds boost (keep foot planted) the turbo has a whine to it, as the revs build engine noise takes over and you cant hear it. It is most obvious at 2500-3000 RPM under acceleration. Is this a normal sound?? can anyone suggest where to take it in Adelaide to get an expert opinion as i want to find the problem (if it has one) before my 3 month warranty runs out.

Any advice would be appreciated

Ps Car is completely stock 90,000km

If you want to take it to a workshop, then there are plenty that provide professional opinions - ATS, BoostWorx, APE, Turbo Tune etc.

Another option is post on the SA section, there are plenty of SA Stag owners that can lend you their ears (and other body parts...) if needed.

Hey guys, I've taken a very short video that hopefully demonstrates the kind of whining noise being discussed here. Our RS4 "S" has a similar whine noise ever since day one when we picked it up, I was once concerned with the sound as well until I discovered this thread. Further comments are appreciated.

Cheers guys.

(video might take a few moments to appear on youtube's server as its only new tonight)

had my s1 for about 5yrs always had a spool whine but when i put a ces split front dump on passengers go wtf it sounds like a jet taking off (wish it would go like one),way louder.

lol, i get that comment heaps and i've yet to do the dump, i think its the intake side that makes the noise tho

just to clear some things up, series 2 c34's run neo motor and turbo, the neo turbo has a larger rear housing compared to an r33 rb25 turbo, the compressor (inlet) wheel is also nylon on neo turbos to reduce spool time

i would say that its the nylon wheel that makes them sound different to previous rb's

the noise in that video is f**k all . get some more tea bags for your stock air box . was funny the other night pulled the air box out of mates u 13 sss blue bird and the whole inside of the box on turbo side of air filter was lined with teabags . like 6 0r 7 all shaped to fit

That sound's nought more than the turbo just starting to think about doing some magic with your engine's volumetric efficiency.

:P

You'll find that it is more pronounced with an SS dump - the OEM cast iron absorbs more db.

When i got may S2 Stagea with 85000km had some turbo whine, i didnt care as i got it cheap so i didnt mind if i needed to put a turbo on it. I have had plenty of turbo cars before and family races turbo cars. The whine was not really that bad was the same as a old VL turbo my old man use to race back in the 90's

After a month of owning it i wanted the change the timming belt and just service every thing on the car as i use it to tow my race car and need it reliable, i have read on the forums before its common the turbo gaskets leak so i changed it, when i took it out there was a very small hair line crack in the turbo gasket. Since that day i have no more whine at all, did nothing else to the car but timming belt turbo gaskets and oil filters, i even reused the air filter as it was so clean when i bought it.

Just somthing you could check if you have any concerns with turbo whine.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated. Rb25det s1 walbro255 fuel pump nismo fpr holset hx35 turbo fmic 3" exhaust freddy intake manifold q45tb q45 maf   Re: s1 RB25det flooding at start up Fri Apr 12, 2013 5:07 am No, I didn't. I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
