djhatton Posted January 27, 2005 Share Posted January 27, 2005 g'day g'day peeps just took the gtr for a blat tonight and just after wasting this kinda hot chick in an xr8, i heard a funny sort of "pfwoosh" noise when i grabbed third and punched the clutch out/acc in. this resulted in like 2psi of boost pressure and no urge whatsoever (...and the falcodore was still munched muahahaa). now, instantly i've thought "hmm must've popped an intercooler hose" but i couldn't really see anything abnormal after a quick inspection. i'll have to confirm this when its not dark, but what other causes could it be? what does throwing a ceramic turbine wheel sound like? fortunately i've never had to experience that... any other ideas? also, am i likely to get detonation/leaning-out if i run the sucker like this till i can get it sorted-out (if i can't do it in my driveway). cheers d Link to comment https://www.sau.com.au/forums/topic/62772-gtr-problems-sigh/ Share on other sites More sharing options...
NXTIME Posted January 27, 2005 Share Posted January 27, 2005 Is the car now running extremely rich and idling rougher? Link to comment https://www.sau.com.au/forums/topic/62772-gtr-problems-sigh/#findComment-1182848 Share on other sites More sharing options...
Nismo32R Posted January 27, 2005 Share Posted January 27, 2005 somehow i managed to snap the rear ceramic turbine wheel on the day of 2004 QLD Drag Combat (i remember it was 45 degree). it drove like a non turbo vehicle. well...actually worse than any NA car. there was no power at all....if you are in the same stiuation....i guess it's your turbo(s).

Skyrine-Dave Posted January 27, 2005 Share Posted January 27, 2005 my bet is a cooler hose somewhere... check the all... check for holes to!, not just a pipe hanging loose Link to comment https://www.sau.com.au/forums/topic/62772-gtr-problems-sigh/#findComment-1182907 Share on other sites More sharing options...
FATGTS-R Posted January 27, 2005 Share Posted January 27, 2005 As above, start at the inlet mainifold gasket and work your way back. I had a similar prob and it was a blown inlet manifold gasket.

Hiroshima Screamer Posted January 27, 2005 Share Posted January 27, 2005 could be any which one of your hoses ... make sure you check all of them . Link to comment https://www.sau.com.au/forums/topic/62772-gtr-problems-sigh/#findComment-1182951 Share on other sites More sharing options...
Amaru Posted January 27, 2005 Share Posted January 27, 2005 If it idles like crap and blows black smoke id say its a hose. If it idles ok then id say youve popped the turbo (does it blow any smoke out the rear when you should be coming onto boost?). When mine let go it didnt make any bad noises, just when I came on throttle again there was no power and white smoke belching out the back (oil burning).

666DAN Posted January 28, 2005 Share Posted January 28, 2005 "pfwoosh" noise I think a blown hose too....I had the same thing happen under WOT, the noise actually made me jump as it was quite loud and sounded like some sort of cool weapon It brought my car to an abrupt stop as it stalled...it was a confusing few seconds as I didn't know what the hell was going on...loud noises, heavy steering etc etc. Check to see if it's actually a tear in the side of a hose maybe....

Duncan Posted January 28, 2005 Share Posted January 28, 2005 yeah normally blown off cooler hose will have you stall...and if you stick with it you could always set the car on fire like skylinegeoff did I suspect turbo....

djhatton Posted January 29, 2005 Author Share Posted January 29, 2005 cheers for the responses fellas the update, after closer inspection and a bit of driving is that its probably not the turbines. it still makes boost (up to about 4-5psi). it takes an age to get to that sort of boost pressure (above 5k) and its making a hissing sort of sound (like air escaping from somewhere) when i'm moving through the revrange. the sound its putting out is quite loud and increases as revs increase. now, it could very well be a bit of silicone hose but i went over it last night and, while i had the sucker on axle stands and attacked every nook and cranny with prying eyes and leadlights, could be wrong. but generally, all the hoses and clamps seem to be just fine. i've also discovered that the previous owner plumbed in some hks piping with a pair of the original/series1 sequential bovs, AS WELL as the factory suckers down low in the guard plumbed back behind the afms. are 4x bov's commonplace from these crazy japanese people!!!?? seems illogical to me! the symptoms. car seems to drive just as smoothly. idle hangs around the 1k mark like it usually does and it still possesses a "bit" of poke. tracking down the problem is gonna be a pain. it doesn't blow a heap of smoke as far as i can tell (no more than usual cos the jap rechip is obviously very very rich anyway). no odd white smoke from the turbos as far as i can tell either. is burnt oil a surefire sign of a stuffed turbine wheel? and how did skylinegeoff burn his line!!???!? by god i surely don't want that to happen! i've owned the thing for like 3 weeks!!!! cheers again. david Link to comment https://www.sau.com.au/forums/topic/62772-gtr-problems-sigh/#findComment-1185086 Share on other sites More sharing options...
Jago Posted January 29, 2005 Share Posted January 29, 2005 4 BOV's!?!?!? WTF? I've heard of 4 before, but it was damn stupid and i didn't really believe it. But yea, i guess they must be uhh, really, cautious about, uhh, backblow etc ?? If you have checked everything else, then (this might sound stupid, but worth a try), check the BOV's themselves, perhaps one of them "carked it", and somehow got "stuck open", or is just really "loose". Not entirely sure if that's possible, but worth checking i guess Link to comment https://www.sau.com.au/forums/topic/62772-gtr-problems-sigh/#findComment-1185205 Share on other sites More sharing options...

ferni Posted January 30, 2005 Share Posted January 30, 2005 Maybe 2 of them aren't actually in use? and they just didn't take them off? Link to comment https://www.sau.com.au/forums/topic/62772-gtr-problems-sigh/#findComment-1187005 Share on other sites More sharing options...
GTR-Ben Posted January 31, 2005 Share Posted January 31, 2005 I have had a similar problem, had 4 BOVs hooked up on one of our cars.. 2 stock, 2 HKS crappers. The car just didn't have the pull, and there was a leaking sound. We first blocked up the 2 stock ones, nope didn't fix it. Then we blocked up the 2 HKS BOV's.. and it was like a new car. Went from doing high 13's to doing high 11's Could quite possibly be the HKS ones..
