[Diy_efi] "reading" a turbo (as you might read plugs"

[Jeff Meager]

This is normal of any turbo with a few kms on it.  Some are worse than
others.  It depends on a number of factors. How hard the car is pushed, ie
how hot it gets to.... hot/cold cycles, rich/lean mixtures, but mainly it
seems more to do with turbo design and materials used to cast the
housings.....

This happened to my Mitsubishi TD05 turbo and is starting on the RX-7 S5
turbo now.  It didn't happen to my Nissan T25G turbo, but that only had
40Km's on it....

I recently rebuilt my turbo (with a kit from Turbo City) and it had
similar cracks in the turbine housing.  They were in about the same
place as the pics, around edges and flanges, the thermal stress from
getting very hot and then cooling is probably most concentrated at those
places.
