Guest Robbieharley Posted September 23, 2012 Share Posted September 23, 2012 Hi All, I'm new to the forum, this is my first post [COOL][/COOL] I have owned my Supra Twin Turbo for around 4 months. I was traveling down to Exeter and while at traffic lights I noticed lots of smoke coming from under the bonnet; after further inspection it looked like the smoke was coming from the back of the turbo, close to the firewall. I now have no tubro in terms of power :-( My boost guage is showing normal boost behaviour and I can hear the turbo spining up very clearly, all normal however my power at all, just as if I have no turbos at all. I think the turbo's have never worked correctly. I could never feel power in turbo 1 only when up to 3-4 grand when the second turbo came online. Just to add, my gearbox was diagnosed as dead, as my reverse has stopped working and in P and N the car acted as if D is selected. A gearbox speclist diagnosed it as dead. I'm currrently looking on eBay to try and find a replecement. I'm thinking my turbos are gone, however before I open my wallet wide I just wanted your advise if possible. Thanks in advance for your time in reading my rant [GRIN][/GRIN] Cheers Robbie Quote Link to comment Share on other sites More sharing options...

Kaan W Posted September 23, 2012 Share Posted September 23, 2012 Thanks Kaan, when I try to access I get "you do not have permission to access this page" Ah! Basicaly you need to pay up a small fee of £10 to access all the behind the scenes goodies on this forum But the link I sent you leads to a guy called David P (a transmission god on the forum!) and he can rebuild your box to take as much power as you need for a price you cant afford not too!

DodgyRog Posted September 24, 2012 Share Posted September 24, 2012 Welcome to the club Not sure where you are in Avon, but Jody T has good knowledge of these engines and is local, might be worth a Pm to see if he can help you out http://www.mkivsupra.net/vbb/member.php?6039-JODY-T Quote Link to comment Share on other sites More sharing options...
Ian C Posted September 24, 2012 Share Posted September 24, 2012 A few questions: Does the turbo still smoke now? Does it smoke on idle? What colour is the smoke - black, blueish, white? Do you get no boost until 4000rpm or is it a case of no boost at all now? What's the fuel economy like? Is it a UK-spec or Jap-spec Supra? That's your starter for ten -Ian Quote Link to comment Share on other sites More sharing options...

Guest Robbieharley Posted September 25, 2012 Share Posted September 25, 2012 Thanks Ian. Please see below my answers to your questions. Does the turbo still smoke now? - No, its not smoking at all now. Does it smoke on idle? - No as above. What colour is the smoke - black, blueish, white? - When I start her up, I see white smoke for around 10 seconds. When I noticed it under the bonnet, it was black smoke coming from the turbo near the firewall. Do you get no boost until 4000rpm or is it a case of no boost at all now? - the boost gauge seems to be boosting normal, however there is ZERO increase in speed etc. (all mouth and no action) What's the fuel economy like? - Poor. Recently it was decreased quite considerably. Around 30% less MPG for circa 6 weeks. Does this point to something? Is it a UK-spec or Jap-spec Supra? - Its a Jap-spec. Any help would be much appreciated Quote Link to comment Share on other sites More sharing options...
JODY T Posted September 26, 2012 Share Posted September 26, 2012 (edited) PMed back As I said I bet ur torque converter/gearbox is goosed and the smoke was prob from the bell housing as something shat itself! I put a bet on it that the engine is fine. U know the box Is less than optimal so replace it with another torque converter. Fix the obvious problem first, don't over complicate it Edited September 26, 2012 by Pixelfill removed the swearing (see edit history) Quote Link to comment Share on other sites More sharing options...
