Can Anyone Help A Turbo Newbie?

[Locknut]

Hi guys,

I've tinkered with cars the last 15 years or so but only recently ventured into turbo engines buying a R32 GTST. Taking her for a cruse today the turbo let out an almighty hiss, a large puff of black smoke out the exhaust then the engine died. I tried to start her again and a real nasty strong burning plastic smell flooded the car, on inspection one of my intercooler pipes had come loose on the intake side of the turbo (the clamp broke) Once I put the pipe back together with a spare clamp she started fine, didn't blow any smoke and ran well but was low on boost, sat on around -5 on the factory gauge sitting on 60kph and boosted up to about +5 when I accelerated (standard engine and turbo running 13psi) I pulled the intake and exhaust off the turbo when I got home to check the impellers but both appear ok and no broken bits. Any one shed any light of what may have happened before I sink money into her blindly??

I have found much great info from this Skyline bible so far but could not see any threads similar to this so I apologise in advance if this has been covered before.

Any assistance would be greatly appreciated

split hose or joiner some splits are hard to see and only open under boost

it wouldnt have done any major damage just check for splits and loose joiners

the hiss, puff of smoke and engine dieing are all due to the intercooler pipe coming off. it happened to me when i installed my intercooler. i think the engine dies because the same volume of air is no longer going to the engine and that stuffs up the mixtures. I dont think it would have done any damage as it would mean less air being forced into the engine and thus too much fuel just making it sort of foul? im not too sure but i checked all my connections and after that everything was fine. In regards to your boost, did you notice any change? I didnt on mine, maybe you have another leak somewhere.

cheers

Really appreciate all your help and advice guys, the previous owner didn’t treat her too good so it may be an ideal time to look at putting some new hoses and pipes on her, maybe the wife will cook me dinner again now I don’t need to replace/rebuild the turbo!!
