Turbo compressor nut failure

Quick background on the car 94 6 bolt awd and I am running a ported 16g with the 20g wheel. Was rebuilt by diesel components last year, although I wasn't the one who paid to have it rebuilt. The guy I bought the car from had it rebuilt and never installed. I installed the turbo along with a fmic and a few other upgrades over the winter. Friday night I had the car running good after having some boost leak issues and idle surge problems.

Drove the car for most of the weekend and on Monday I was on my way home when some guy in a mustang comes up behind me revving his engine at me and what not. He comes up along side of me after leaving a light and I hit it in second and had absolutely nothing, no power like it was running N/A. Get home and take the intake pipe off and the nut on the compressor wheel is gone and the wheel itself is crooked and wedged against the compressor housing. Looked for the nut and it wasn't in the intake pipe, maybe it made it past the fins?? The fins themselves don't look beat up and only have small chips where it looks like it hit the nut a few times.

My question is if i can find the nut and it is not completely destroyed, would it be worth trying to put it back together or is it something where the turbo probably needs to be re-balanced or possible now have bad bearings and is not worth rebuilding again. ( the guy paid some $700.00) to have it rebuilt and at that amount id rather put it towards a new turbo. I am going to go home tonight and mess around with it some more, first to try and find the nut haha and go from there.

Anyone ever experience this??

Re: Turbo compressor nut failure

I'd guess the nut is somewhere in the intercooler piping, or maybe even in your intercooler. Rebuild would be a must here in my book, no reason to chance it and risk losing a motor too.

Yeah thats my guess, i was reading a lot about it happening to other people and they say that some red locktite should be on there. I didn't see any trace of that on mine, but i'm not sure that's a must either. oh well it's a shame it happened i suppose it's time for the bigger turbo i wanted haha.

Sorry to hear about your nut.

LOL

I had to. I would do what goodhart said. Sounds like your fins got all boogered up in the process.

Re: Turbo compressor nut failure

Yeah i may try and spin it up if i find the nut with an air chuck and compressor and see what happens but more than likely ill be looking for a new replacement.

Thanks for the concern with my nut!

Full rebuild or new turbo. Find the compressor nut to avoid it going in the motor.

Re: Turbo compressor nut failure

Yeah it is much worse than i thought it was. I did find the nut however, it was stuck inside the filter so thats good.
