993 Turbo Head Stud? Superseded part number

[jamesjedi]

Hi,

I see that the 993 Turbo head studs have been superseded by a new part number.

The old number looks like - 993.101.170.51. It looks to have been changed to 993.101.170.53. Is it the same?

I think the stud ending in 51 was used on the RSR.

Thanks to anyone who knows.

Check your lengths because longer, less expensive ones that are identical are used on the water cooled turbos.

The .51 was used in all 993 RS/Cup/RSR/TT/GT2/GT2Evo

supersession just means a new supplier of the same spec part

Thanks everyone for the replies. Hopefully the new supplier make it as well as the old supplier.

I was thinking of using them on a 3.0 L.
