Car smoking after 17t install

[tobi01]

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 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?

Thanks

Tobias

Why not contact Torcoils directly? On social media, they're touting their products as good. But these ignition coils burn out, the upgraded oil cooler is extremely poorly finished... Now it's the turbos that are smoking.

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

I sincerely doubt that crushing the inlet will blow the turbo... I also don't know if VIV cartridges are identical to Torcoil's... But again: why don't you order cartridges from Torcoil? Tomorrow, if my Hydras blow, I'll contact Hydra... I'm not going to try to install VIV, RB, or CTS cartridges... You understand my reasoning

I asked because at least the shop do not offer the cartridges separately. I wrote them an email and wait for the reply.
