Matt B Posted July 10, 2004 Share Posted July 10, 2004 All, I need some advice please...?? I got my car back from Dude on Thursday after having a FMIC amongst other things fitted. Anyway when driving I was not getting anything above 0.5bar boost and so I checked hoses as per Dude's advice and sure enough one had come off. I've since replaced the hose and made sure it was secure. Went off down the road hit 1.2bar.... Great I thought, however the next time I tried I had no boost at all (Won't go above 0) I checked the hoses again but can't see any loose ones. All seem secure. The worst thing is the car is smoking all the time once warm. Does not happen when cold but once warmed up I get big puffs of Blue smoke on lift off and when accelerating, even on tick over it smokes a bit. So I wondering if my blowers have gone or what else it could be??? Any advice is greatly appreciated as I'm very concerned.... Link to comment Share on other sites More sharing options...
michael Posted July 10, 2004 Share Posted July 10, 2004 Originally posted by Matt B Any advice is greatly appreciated as I'm very concerned.... Have you taken it back to Dude? That would be my first step if it worked OK prior to it going in, I'm sure he'll be happy to take a look over everything. What "other things" did you have fitted at the same time? It's not something as trivial as fuel cut as a result of mods is it? Link to comment Share on other sites More sharing options...
TRD3000GT Posted July 10, 2004 Share Posted July 10, 2004 oh dear mate, Sounds like turbos to me. Link to comment Share on other sites More sharing options...
osso Posted July 10, 2004 Share Posted July 10, 2004 Sure its nothing simple like a huge boost leak with the newly fitted FMIC? Link to comment Share on other sites More sharing options...

Matt B Posted July 10, 2004 Author Share Posted July 10, 2004 Cheers guys, I've spoken to Dude a couple of times so I know what I'm looking for now. I'm gonna take out the drivers lamp to check the hidden clamps. I was just a little spooked by all the smoke as well. Did not think the hose being off would cause smoke??? I just don't wanna have to drive all the way back to Dude cos it's like over 100 miles from where I'm staying at the mo. Link to comment Share on other sites More sharing options...

Matt B Posted July 11, 2004 Author Share Posted July 11, 2004 Bad news I'm afraid.... I've had the drivers headlight out and the battery. All hoses are secure and have been re-tightened... I can't even drive it really at the moment as it's smoking really badly. People were flashing me earlier after I took it out to check... Really can't understand what's happened??? Everything else looks and seems fine... Link to comment Share on other sites More sharing options...

MONKEYmark Posted July 11, 2004 Share Posted July 11, 2004 you not done a piston in have you. i was in a mini convoy with mate in his skyline other mate in uk spec supra me in mine and a escort cossie and mr2. mate in skyline shoots off at high speed other mate in uk supra gives chase and going round a sharp bend at high speed a big cloud of white smoke starts coming out of supra, i thought he had blown a turbo but in the end it was a piston. you you have many safety and cooling mods??

Matt B Posted July 11, 2004 Author Share Posted July 11, 2004 Originally posted by MONKEYmark you you have many safety and cooling mods?? Not sure exactly what you mean mate? I'm running a S-AFC to control fueling so that should be fine and a AVC-R to monitor and control boost. Also got a restrictor ring to limit it to 1.2 bar. Cooling was standard J-spec until the FMIC was put on... The smoke coming out is deffinately Blue Cheers. Link to comment Share on other sites More sharing options...
dude Posted July 11, 2004 Share Posted July 11, 2004 Matt give me a bell when you get up , what boost did you say you hit when you put the clips on ???, blue smoke is not good Dude:flame Dev Link to comment Share on other sites More sharing options...
Matt B Posted July 11, 2004 Author Share Posted July 11, 2004 Well it looks like my turbos have given up the good fight and I'm left with a 0 boost smoke machine.... Link to comment Share on other sites More sharing options...
osso Posted July 11, 2004 Share Posted July 11, 2004 I am finding that hard to believe, you said you boosted fine to 1.2 bar, then the second time you only had 0 bar.. didnt you feel the car being hesitant? or see a cloud of smoke the second time round when you got 0 bar?

Matt B Posted July 11, 2004 Author Share Posted July 11, 2004 I did not notice any smoke but there may have been. I was watching the boost gauge... I still live in hope but with all the smoke it does not sound good. Link to comment Share on other sites More sharing options...

Suprash Posted July 12, 2004 Share Posted July 12, 2004 Matt, what other work did you have along with FMIC. Blue smoke means your burning oils somewhere, and is most probably where you have blown your turbo seals. To be honest mate I wouldnt drive it until you have had it checked over as if your burning oil you could be in danger of using oil your oil and seizing your engine. My turbos blew after going FMIC, and walbro/FSE, and I had blown turbo seals, which would have pretty much dumped all the oil within 30 miles. Feel for ya man Link to comment Share on other sites More sharing options...
michael Posted July 12, 2004 Share Posted July 12, 2004 Is this a case of the turbo seals being a little worn anyway but still holding until specific flow enhancing mods are added and backpressure reduced thus causing them to open more than previously?

Suprash Posted July 12, 2004 Share Posted July 12, 2004 Whow knows mate, your now diving into the realms of serious mechanics. What do you mean by "specific flow enhancing mods" ???? And "backpressure reduced" ??? Are you sayig this happens when say going FMIC or Walbro/FSE ???? Link to comment Share on other sites More sharing options...
michael Posted July 12, 2004 Share Posted July 12, 2004 I don't know if something like an FMIC will have the same effect but I suspect the turbos on my car were in need of replacement shortly after I bought it. At the time it has a standard exhaust with CATs and I got no smoke, no oil loss. I added the NuR and decats which reduced the back pressure - apparently this then had the effect of failing to keep the turbo oil seals tight (CW helped diagnose this in an old thread - he suggested stuffing scouring pads up the exhaust to get the backpressure back and test for smoke). Just wondering if the FMIC has helped to highlight the issue further? Link to comment Share on other sites More sharing options...
Suprash Posted July 12, 2004 Share Posted July 12, 2004 mmmmmm, some good points dude, but your asking the wrong guy, anything about getting stoned Im ya man, back pressure and stuff, who knows............ Hopefully someone will elaborate on this Link to comment Share on other sites More sharing options...
Roy Posted July 12, 2004 Share Posted July 12, 2004 matt - i feel for you mate. as you know, i thought mine had recently gone too but it turned out not to be the turbos but something else (just exactly what is another question) ... Link to comment Share on other sites More sharing options...
SirCharlesworth Posted July 12, 2004 Share Posted July 12, 2004 I know i'm an outsider of the supra world but this thought did cross my mind as a cause: You said originally that a bad hose was causing you to only be able to make .5 bar,(now i'm assuming here it was a boost hose) because of this, i'm pretty sure that the turbos would be running 100% all of the time to try and make the desired boost (wastegate actuator would never recieve enough pressure to open the wastegate) so if you were throttling it hard, then the turbos would have been running way over the top, which caused seal failure. Just an idea, i'm probably way out but it's worth a thought! Charlie Link to comment Share on other sites More sharing options...
osso Posted July 12, 2004 Share Posted July 12, 2004 The hose was probably one of the pipes from the pressure lines that controls the actuators which open up the valves to start the 2nd turbo spinning.. Link to comment Share on other sites More sharing options...
