Blown R33 Turbo

[wagsR33]

guys i was in full throttle into 3rd when i herd a massive bang and lost almost all power...

when i put my foot down it chockes and will only jump a little while it goes up the vacum line on my boost gauge (which it does exeptionally fast) as soon as it hit boost it just goes no where.

clearly i am thinking the turbo is blown since there is no flutter and will not show and boost on the gauge as well as heaps of smoke comming out of the exause

but why wont it idle properly or drive properly or even go over 2000rpm before chocking. i thought if i blew the turbo it would drive as a non turbo would??

most likely yoiu have blown a turbo. And it will run like crap. Some cases it would run like a non turbo. other cases it would feel like no matter how hard u try the car wont move much at all.

pull off the intake pipe leading to the turbo (rubber) and have a look at the comp wheel

when i blew my turbo in my 200sx there was a whole heap of white smoke coming from the exhaust.

The reason it may not idle properly is most likely due to the Oil from your turbo going through the motor and fouling your plugs...

As far as not going over 2000rpm without 'choking', I don't know what you exactly mean by 'choking' though could be in safe mod which I doubt so I would say it is just way to rich and getting bugger all spark.

Take it to a workshop mate. There are plenty of them in sydney and won't cost much to get them to have a look and diagnose whats wrong.

well have you checked that any of your cooler piping hasn't blown off or developed a large leak on one of the joins? Also what colour is the smoke? If its black its fuel, white is water, blue is oil.

good thing i checked the cooler piping before ordering a new turbo!! the cooler piping just under the airbox had blown where it meets the stock piping but only to the side and not entirely off so it was still running but terribly and not boosting. i reconnected the pipping and the idoling returned to normal and the black smoke stopped after a few seconds. i took it for a drive and its boosting but ht ecar is sluggish and miss fireing. i am guessing this is because the spark plugs are in ruins after flooding the engine so much and so many times????? so i will buy a new set of them and see she returns to her boosting best

i've had both these problems, i have blown cooler pipes off (when i just bought my rb20 silvia) the guys hadn't put them on poperly this makes the car choke and stall when trying to move it. This afternoon, the turbo actually blew and i knew it was going to at some point as i was an idiot, i had no boost controll running for the turbo (usually watched the gauge) and no bov running. Was going to put on a bov n attach a bleed type boost controller but now i can't! ahh but yes ur problem is definatly a blown turbo, i'd say the exhaust wheel is blown bad luck, hame!
