Nic Posted August 27, 2005 Share Posted August 27, 2005 Are you positive it is the turbo and not something else making the noise? If you rev the engine whilst parked is the noise coming from the turbo? Quote Link to comment Share on other sites More sharing options...
ADD Posted August 27, 2005 Author Share Posted August 27, 2005 you cant hear it when you just reving the engine, it happens from about 1800rpm untill about 3000rpm but when you boot it, the noise goes away! (when travelling that is) Quote Link to comment Share on other sites More sharing options...
Branners Posted August 27, 2005 Share Posted August 27, 2005 import or UK spec? The import turbos tend not to whine before they go as they simply disintegrate, the UK specs whine when the blades start to fall apart. BPU will certainly kill the turbos if they are on the way out.

Branners Posted August 27, 2005 Share Posted August 27, 2005 they arent known for doing the death whine, as the exhaust side of the turbo is made from ceramic it tends to just shatter when it fails and disappears out the exhaust (or gets trapped by the cat if you still have one). There have been problems with the manifold gasket leaking slightly and causing a whine. Certainly if you go BPU then it will show if the turbos have a problem as the extra boost will kill them pretty much straight away. Whoever is doing your BPU work can probably check the turbos and manifold gasket while they are at it. JB Quote Link to comment Share on other sites More sharing options...
ADD Posted August 27, 2005 Author Share Posted August 27, 2005 how much are we talking for new turbos? Quote Link to comment Share on other sites More sharing options...
Nic Posted August 27, 2005 Share Posted August 27, 2005 how much are we talking for new turbos? They are not cheap from Toyota there, quite a bit cheaper here from memory but still not exactly cheap, if you need a price let me know. A set of second hand ones would be cheaper but then there is always a risk of them going too, other alternative is get yours rebuilt with new internals or speak to TerryS/Migster about the BL budget single kit they do.

ADD Posted August 27, 2005 Author Share Posted August 27, 2005 i have just had a look in the bay and im getting quite a bit of oil splat from the pipe joining on to my dump valve (standard one) on the turbo side, also it does whine when idling! bollox!

Branners Posted August 27, 2005 Share Posted August 27, 2005 small amount of oil in that pipe is normally okay I think. If the whine is there when idling then its not going to be the turbos as they wont spin up without some load on the engine. Sounds like its a gasket somewhere.

ADD Posted August 27, 2005 Author Share Posted August 27, 2005 ok branners thank you for your advice, i shall get it all checked! Quote Link to comment Share on other sites More sharing options...
ADD Posted August 27, 2005 Author Share Posted August 27, 2005 branners, if i did have problems wiv the turbos and all i was doing was full decat/fcd/spark plugs/restrictor ring, would it finish them off? Quote Link to comment Share on other sites More sharing options...
Clarkey Posted August 27, 2005 Share Posted August 27, 2005 branners, if i did have problems wiv the turbos and all i was doing was full decat/fcd/spark plugs/restrictor ring, would it finish them off? Afraid so mate! Going from 11.5psi to 17.5psi ... your turbo's will have a cardiac arrest. It sounds like you want more performance .. as your going BPU so if it is your turbo's ... Forget hybrids .. go single turbo. Quote Link to comment Share on other sites More sharing options...

Clarkey Posted August 27, 2005 Share Posted August 27, 2005 how much we talking clarkey? I think it would depend on what mod's you've already got. My car was already BPU .. exhaust, midpipe, downpipe, FCD, Walbro .. I'd already got those.. and £4k got me .. BL Budget Single, 550cc injectors (cleaned & flowtested), S-AFC2, S-ITC, replacement SMIC (mine was fecked), turbo blanket, AEM WB 02 AFR Gauge. Hybrids .. including fitting are £1800 .. but you still need the supporting mods for it. Uprated injectors, fueling computer (EManage or SAFC/S-ITC), a decent IC. I worked it out on an excel sheet .. and the costs of Hybrids v Single T61. The single was £600 more. That £600 is worth every penny!! There is a thread on here Simple choice really ....

Clarkey Posted August 27, 2005 Share Posted August 27, 2005 That's what credit card's are for ! lol ... either way mate - it's going to cost you money. But get it 100% diagnosed .. if it is turbo's first. You never know - might be something really simple. Quote Link to comment Share on other sites More sharing options...
ADD Posted August 27, 2005 Author Share Posted August 27, 2005 thats very true, il get it checked on monday! Quote Link to comment Share on other sites More sharing options...
Branners Posted August 27, 2005 Share Posted August 27, 2005 branners, if i did have problems wiv the turbos and all i was doing was full decat/fcd/spark plugs/restrictor ring, would it finish them off? on higher mileage cars a decat and exhaust is enough to reduce the back pressure against the turbos and so can lead to a bit of smoke, people have put the cats back in and the smoke goes away. The reduction in back pressure and the additional boost will show up any faults in the car. I have a single turbo on my UK spec as my stock turbos failed around 10,000 miles after going BPU, but the car does have 130,000 miles on it.

tucky40 Posted August 29, 2005 Share Posted August 29, 2005 Guy's and gals, i've just bought a jspec TT and its my first turbo car.....I've got to admit the turbos make alot of noise. Should healthy turbos be making any noise at all?? Its a real pronounced hollow woosh not sure if I'd call it a whine Quote Link to comment Share on other sites More sharing options...
Jake Posted August 29, 2005 Share Posted August 29, 2005 A sort of whistling type noise is perfectly normal from the first turbo. Quote Link to comment Share on other sites More sharing options...
Kopite Posted August 29, 2005 Share Posted August 29, 2005 has anyone ever had a 1st turbo blow? Quote Link to comment Share on other sites More sharing options...
Branners Posted August 29, 2005 Share Posted August 29, 2005 yes, first turbos have been known to go. Normally due to a lack of care on the car while in Japan. First import I saw with blown turbos had lost both of them. It was a stock car running stock boost... JB Quote Link to comment Share on other sites More sharing options...
