How many miles on your N54 aftermarket twins?

This thread is for people with aftermarket twin turbos (VTT, RB, Hexon, etc) to post how many miles they have on their current setups. Or if you had aftermarket twins and they failed, please post here as well.

It seems like everyone recommends to replace failing stock turbos with aftermarket ones, and say that they'll last longer than stock, but I've seen zero proof of this. In fact, it seems that the opposite is true.

So for anyone with aftermarket turbos (still working or failed), please post the following information:

- Turbo manufacturer
- Model
- Current mileage on the turbos
- Date of install
- Boost levels, other mods, etc.

Thanks!

Head over to n54 tech and there's more than a few who have had RB's fail under 2k miles and get stuck with the install and uninstall cost and end up loosing a couple grand because of it.

They have 10k after rebuild or they had to be rebuilt after 10k?

Bought them used. Sent them to Rob for a full rebuild and VSR balancing. I have since put over 10k miles on them.

Now when you say smoking, you mean coming from the exhaust correct?
