01 · Start with the evidence
Aftermarket claims and factory references stay separate. The directories below connect those records to people, materials, documented builds and reviewed social sources.
Dossier 01
Every entry names its seller, links to the listing it came from, and carries the date the price was read. 106,534 carry a dated price. Nothing is inferred: where a seller does not state a material or a fitment, the field stays empty rather than being filled with a guess.

Transcribed from 38 Porsche parts catalogues covering every generation from the 356 to the 991, plus the 914, 924, 928, 944, 968, 986 and Carrera GT. 47 of them have additionally been read line by line against the drawing they belong to.

141 competition manufacturers, 204 firms that will make a part to a drawing, 59 used-parts sources. Searched in 63 languages, because a Japanese specialist and a Polish restorer do not advertise in English.
435sources in 62 countries

97 official sites checked for the services and parts they actually publish. Each account keeps its Instagram source, website relationship, review date, and any limits in the evidence.

12,603 parts state what they are made of, split by grade rather than by family — Ti-6Al-4V apart from Ti-6242, prepreg apart from wet lay-up, because the difference is the reason to buy one.

13 documented builds — forum threads and owner build records — preserve their source trail; 2 site-built specifications name every position and leave unsupported catalogue gaps explicitly empty.

One verified reference, shown with the drawing and the questions still open.
This is the 993 Turbo engine carrier. It is a structural part, it was read in the factory parts catalogue rather than copied from a listing. The reviewed record does not establish a compatible aftermarket replacement; that is a limit of our research, not proof that none exists. Read the reference and its evidence →
Factory material and weight remain unknown in this record. Before comparing an alternative, establish the application and the missing specifications.Follow the worked example →
03 · Field note
Catalogue and factory claims come from manufacturers or Porsche publications. Real-world outcomes need a different evidence trail: documented engine threads stay separate from site-built specifications, while broader owner experience belongs in theforum.

Counts on this page are computed from the data at build time, not written by hand, so they cannot drift away from what the site actually holds.
