Compressor housing???

[jasjamz]

It's a garrett M11. Stamped numbers read: 409722-5 M. What turbo does this go to. I know it old but was wondering if it will fit a 63 or 66 mm turbo. Thanks.

Although I do not know what turbo that cover came on stock, I can tell you, that most stock OEM Garrett turbos had very small compressor wheels in them from the start. The chances of a 63 or 66mm compressor wheel fitting without being touched are very slim. Generally, the cover has to be machined out to accept the larger compressor wheels. The stock 86-87 TBO-348 turbos compressor cover can be machined out to accept a 66mm inducer compressor wheel and that's it. No way of identifying what turbo that came on with the numbers given. You might try contacting either PTE or Limit Engineering for further ID help tho.
