jimmy_supra Posted September 30, 2013 Share Posted September 30, 2013 Went out for a drive in the Supra earlier the last one for a while as the tax runs out today. All was well and the turbos were coming online and off as they should. I had just gone up a pretty big hill on a main stretch of road boosting at 1.2bar. Then I reached the top let off and all was still fine until I accelerated again at which point there was no boost. There was no noise no smoke just a sudden lack of power. I pulled over had a good look at all the intercooler pipes and vacuum pipes, they all appear to be fine. There has been a slight whistling noise lately coming from the turbo, could this be related? My only thought at the moment is that the turbo's have given up on me or at least one of them however there was no black smoke or noise to indicate this. Has any one got any ideas? Any help much appreciated Thanks James Quote Link to comment Share on other sites More sharing options...

jimmy_supra Posted September 30, 2013 Author Share Posted September 30, 2013 Yes mate just drives like a Under Powered NA. It's like a boost pipe has come off bit I can't see any evidence to support that. Boost gauge reflects that by only moving to 0 I'm hoping its a pipe but it may be the turbo. However I thought turbos went with a bang usually. Quote Link to comment Share on other sites More sharing options...

Gpro Posted September 30, 2013 Share Posted September 30, 2013 1st turbo blown - my guess Quote Link to comment Share on other sites More sharing options...
jimmy_supra Posted September 30, 2013 Author Share Posted September 30, 2013 After looking at various other threads I'm leaning towards the first turbo being blown. At least it's happened at the end of the summer. I have 6 months to fix it. Any one know some one selling a first turbo? Quote Link to comment Share on other sites More sharing options...
marc_p Posted September 30, 2013 Share Posted September 30, 2013 Is there no boost at all? Put it into TTC and see what happens. Quote Link to comment Share on other sites More sharing options...
jimmy_supra Posted September 30, 2013 Author Share Posted September 30, 2013 No boost at all I can't remember how to put it into TTC also I have got a Apexi AVCR installed so is it possible to do TTC with that connected? Quote Link to comment Share on other sites More sharing options...
jimmy_supra Posted September 30, 2013 Author Share Posted September 30, 2013 Looked in the intercooler and air filter pipe work no sign of oil it's all dry. Quote Link to comment Share on other sites More sharing options...

It's easy enough to do, there is the guide on here somewhere, you can do it with an AVCR. Looked in the intercooler and air filter pipe work no sign of oil it's all dry. This has me doubting that the turbo has gone, you will usually get some sort of sign (Noise, Oil, Smoke), they don't tend to just stop after working perfectly fine. By putting the car in TTC and seeing what happens, it will help with diagnosis. Quote Link to comment Share on other sites More sharing options...
jimmy_supra Posted September 30, 2013 Author Share Posted September 30, 2013 Cheers mate I have found the link for TTC it was saved in my favourites so I'll try it and see what the outcome is. Quote Link to comment Share on other sites More sharing options...

Gpro Posted September 30, 2013 Share Posted September 30, 2013 (edited) TTC is to dignose a problem with the 2nd turbo. TTC aint going to make the 1st turbo work again. A simple solution is take the 1st turbos inlet elbow off and turn the engine on and see if its spins and check the fins. (Most common is the exhaust turbine failure) Edited September 30, 2013 by Gpro (see edit history) Quote Link to comment Share on other sites More sharing options...

jimmy_supra Posted October 1, 2013 Author Share Posted October 1, 2013 Put it into TTC and it's the same. Start to accelerate and there is a noise like the air is being released so I'm thinking the first turbo is definitely broken. The noise I'm guessing is the pressure trying to build and then being released via the easiest path. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted October 1, 2013 Share Posted October 1, 2013 No its probably a hose. Have you checked EVERY hose and clamp between the turbos and the intercooler? A lot of people say yes when they havent, Quote Link to comment Share on other sites More sharing options...

If you can hear it spooling then it must be working. like above check all hoses from turbo to intake. Also if you have the tools just take the 1st turbo intake elbow off and have a look Quote Link to comment Share on other sites More sharing options...
Steve Paine Posted October 1, 2013 Share Posted October 1, 2013 I had a hose on my fmic that kept popping off and that left the car driving like an NA. Sorted that then a pipe on the boost control had a split in it leaving the car over fuelling and running like an NA. Like said above. Check all the pipes. I feared the worse and was pleasantly surprised, but it did take LeeP at SRD to sort it out for me! Quote Link to comment Share on other sites More sharing options...
jimmy_supra Posted October 1, 2013 Author Share Posted October 1, 2013 I have had a look at all the hoses I can see but I will work through them all one by one at the weekend and check them all for splits etc and take it from there. I hope it is just a hose. Here's hoping, I'll update with my findings at the weekend. Quote Link to comment Share on other sites More sharing options...
jimmy_supra Posted October 1, 2013 Author Share Posted October 1, 2013 After checking the hoses I'll try the turbo elbow as I have got the tools. That is if I don't find a damaged or loose hose. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted October 2, 2013 Share Posted October 2, 2013 Look at the IC to TB pipe joint down by the side of the battery. In fact don't just LOOK at the damned thing, remove the pipe to chassis clamp, give it some proper tugging and twisting grief, get a light down there, and you'll probably find one of the rubber hoses is partly blown off. If I had a hundred quid for every "I have checked EVERY HOSE, 10 times" story only to find they have done it wearing evening dress, white gloves and with a morbid fear of getting dirty, and a pipe IS off, I'd be a wealthy man Quote Link to comment Share on other sites More sharing options...
