Suggestion · Original poster
to set aside some $ for a few months, and either i'll have the 7g for a used 2.5 installed, or maybe find a clean S, 7g would go a long way towards a S, or save for another few months and just go 3.4 swap and be done

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.

ok i'll bite,
since i'm buying a new engine anyway
is the 3.4 swap as easy as pelican parts makes it sound?
because, it's looking like the price difference from a 2.5 to a 3.4 is only a few grand, and since i'm throwing grands around anyway might as well go bigger, right? Reasonable thinking?
so i'm curious
plan is... to set aside some $ for a few months, and either i'll have the 7g for a used 2.5 installed, or maybe find a clean S, 7g would go a long way towards a S, or save for another few months and just go 3.4 swap and be done
crazy? blown Porsche engines tend to do that to a man :dance::dance::dance:
The 3.4 is our least favorite M96 engine displacement. Definitely the most problematic of the engine family. We see twice as many of them as all other engines in regard to internal problems.
Its always been this way. The 3.4 has historically had the most issues. Its the only engine that has an equal amount of IMS/Cracked Heads/ Cylinder failures.
Yesterday we received 5 failure calls, all but one of them were from 3.4 base engines... 5 calls in one day is a new record, puts us at 7 for the week which also tied the record, but we still have today to go.
The 3.2S engine from 2000 is one of the best IMHO, Dual Row IMS bearing, late IMS drive chain and larger capillaries inside the cylinder heads make it show up less here than all other Boxster engines combined. It also has the most substantial cylinder walls and they very, very seldom ever have cylinder issues.
This comes from trend data collected and first hand experience supported by years of research.
Good enough for me! NO 3.4, look for a clean 2000 S instead
What were the issues with the newer S's? Found a nice 550 spyder at a good price I'm seriously considering....
Regarding 2000 3.2s Jake's opinion/data was echoed by a Porsche service tech that I talked to a number of years ago. He mentioned that he had seen coolant/cracked head issues though. He referred to the 2000 as "a good year"
I please to see a dual row IMS bearing when I pulled it.
