Hey Folks,

I recently installed Torcoils 17Ts ( https://torcoils.com/de/products/td...bmw-335i-335is-335xi-e90-e91-e92-n54-b30-3.0l ) only after a few pulls, car started smoking. As per attached log my boost dropped und wgdc sky rocked above 6k. I suspect that my inlet/s collapsed and forced the turbos to overspin.



I did not dropped my downpipes yet but will do soon. I assume that at least one shaft seal is blown or even the rotary lost it's integrity.



I am not sure what to do šŸ˜” Do you think VIV 17T cartridges ( https://vivautoparts.com/products/t...i-3-0l-n54b30-oem-size?variant=42086719291567 ) do match my turbo housing? Would a rebuild kit be the way (of course only if compressor wheel and turbine are still intact) to go or do I need new turbos?


Log


Thanks

Tobias

Rear turbine is oily. I found the rear inlet popped of the snout and bended against the firewall. The inlet was squished partially and I can imagine that it collapsed in under pressure conditions.

Root cause is possible and cannot blamed to turbo manufacturer in my opinion. I will ask Torcoils if they sell cartridges solely. Or do you think VIV ones will match as they are most likely all the same

Question is if I need to replace both cartridges as the front turbo is dry but I do not want to do the labor twice 😭
