E63 AMG M157 Turbos?

Who makes the stock turbos on the M157 engine, are they Garret turbos or Borg Warner from factory? I remember reading on the weistec site something about Garrett and tried searching around, but any answers would be appreciated. Also, what size are they?

There is no exact designation on them in terms of an aftermarket unit but they sit between GT20 and GT22

How long do you expect these turbos to last with AMS tune only?

Our tune will not shorten the life of the turbos at all.

Looks like this thread's been left over with.

It should be manufactured by Honeywell for Garret

Regarding the size and SPEC....not so sure........There is aftermarket mod kit for the blades and spool wheels.....like from MAMBA, which not so compromised.
