These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

12 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

We have tested two engine for a year and a half all track use not a minutes problem with them. Some of you will be racing against these motors this year. There is no problem with exspansion, this is done ever day with Subaru WRX, Porsche 951 2.5L & 3.0L turbo, Honda, Ferrari just to name a few.

That is excellent to know that there is another option outside of Jake on the East coast if Jake takes 8-9 months to rebuild an engine..

POST 12Original post

Quotes source post: 8407881

This is interesting. How are those test cars running? Have you had many takers yet? Any advantages/disadvantages to running cast iron versus lokasil/nikasil? Assuming one would reuse their existing "in spec" (or new) factory pistons, what is the cost for your ring pack on a 3.4L? 3.6L? Can you also do bigger bores? Edit: I think I may have found my answer in the link below regarding iron vs. aluminum and nikasil. Thanks Charles! https://rennlist.com/forums/996-foru...000-miles.html
