ballsoutracing Posted August 20, 2003 Share Posted August 20, 2003 Can anyone help? I have had and loved my 94 tt for a year now, and have always enjoyed the pleasent whizz of the turbos, I thought that was normal. Recently the whizz has become harsher and louder. It starts at about 2,000 revs and continues to the cut out, you can only really hear it at low speeds and high gears bringing the turbos in slowly. The car seems to boost ok and there is no smoke out the exhaust . There are no engine mods to mention. Wot could it be, is no1 turbo on its way out? Any advice would be greatly appreciated as I am lossing sleep over my baby:( Link to comment Share on other sites More sharing options...
Keith C Posted August 20, 2003 Share Posted August 20, 2003 Is it a J-spec car? It sounds like a hose leaking to me. Link to comment Share on other sites More sharing options...
ballsoutracing Posted August 20, 2003 Author Share Posted August 20, 2003 Its a J spec Gz Auto. Thought it might be a pipe or valve, how do you know witch one though. Thanks for the response. Link to comment Share on other sites More sharing options...
Keith C Posted August 20, 2003 Share Posted August 20, 2003 Unfortunately, by the incredibly boring and laborious task of visual inspection of each one... Link to comment Share on other sites More sharing options...
Marco Posted August 20, 2003 Share Posted August 20, 2003 I had the same whistle! But it got louder and louder! One of my hoses was leaking (small hole), but when I had them all replaced, the whistle stayed. So basically the turbo's were knackered and had to be replaced. (they still seemed to boost OK-ish) I hope for you its just something with the hoses, otherwise it might be really expensive. Link to comment Share on other sites More sharing options...
FaithStalker Posted August 20, 2003 Share Posted August 20, 2003 if they boost ok - why bother replacing them? Link to comment Share on other sites More sharing options...
ballsoutracing Posted August 21, 2003 Author Share Posted August 21, 2003 The turbos are boosting well and the car has only 43,000 miles on it (if they are to be believed), they look like new so I really hope they arn't the way out:( How much is a second hand set, or can they be re-conditioned, wot would the cost be.

ad500 Posted August 21, 2003 Share Posted August 21, 2003 Originally posted by ballsoutracing How much is a second hand set, or can they be re-conditioned, wot would the cost be. I was told this week there about £800 each(on an exchange basis) from Toyota, this could vary abit of course. For that price your probably not too far away from getting hybrids. If you can source a second hand set you would imagine they would be less than this but TBH its waiting for a set to come up. Try JPS, Option etc to see if someones upgraded recently and left their old set. I don't know whether id trust a 2nd hand set without having them reconditioned, thats only my opinion. Ive remember hearing the figure £500 for reconditioning turbos and cant for the life of me remember whether thats each or both. Maybe someone will clarify that bit, alternatively just ask the garages when you call. Link to comment Share on other sites More sharing options...
Ian C Posted August 21, 2003 Share Posted August 21, 2003 I've got a low mileage set of j-spec turbos sat clean and bagged up if you get desperate, less than £800 each as well -Ian Link to comment Share on other sites More sharing options...
Steve W Posted August 21, 2003 Share Posted August 21, 2003 ....less than £800 each as well .... UNLESS Toyota can't get 'em for a while... in which case they're a LEEKLE bit dearer ? ! ? EH ! Link to comment Share on other sites More sharing options...
ballsoutracing Posted August 22, 2003 Author Share Posted August 22, 2003 So do good turbos make no noise, are do they all whine a bit. Oh can get a second hand set for £450. Link to comment Share on other sites More sharing options...

No they will make a noise, like a silent whistle. BUT mine were almost deafening, so loud! Not pleasant Link to comment Share on other sites More sharing options...
ballsoutracing Posted August 22, 2003 Author Share Posted August 22, 2003 They are not that bad, you can only hear it in high gears, boosting gradually, with the window open. They still sound quite fit, just louder than I have noticed before. The other thing is there is no whizzing when reving the engine from under the hood. Swaping between Super and Premium unleaded couldn't have any thing to do with it could it? Surley not! Link to comment Share on other sites More sharing options...
Steve W Posted August 23, 2003 Share Posted August 23, 2003 .....like a silent whistle..... ? ? ? NOW, I'm not one to "pick nits", but, WHAT the HELL is THAT ! ? Is that like a DRY PUDDLE or LIGHT BLACK or DARK WHITE ? ? ? ....only jossin', know what you mean really.... a 'background' whistle just enough to let you know when they're startin' to "TRY".

Nic Posted August 25, 2003 Share Posted August 25, 2003 Do you have an external blow off valve fitted? It could be this leaking under boost. Link to comment Share on other sites More sharing options...
