Read evidence and context
Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

An engine with a short life because it was replaced with the 2.7 DFI unit after only 5 years.
Leading evidence: 'Replace engine' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace engine' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
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.

CO2 and other stuff, didn't need to be as big.
As someone else said the non S 987.2 didn't get the DFI engine until the 981.
I would be amazed if the wikipedia page didn't give a nice break down as to why.

I think the answer lies in horsepower outputs and engine design/technology.
Just interesting how they moved from 2.7 to 2.9 to 2.7
That bit is a mystery. It is not like the 2.9 is a stretch of the original 2.7, but a completely new motor, because it did away with the intermediate shaft.
performance car manufacturer's sales departments use HP ratings, displacement numbers and 0-60 times as like garnishes on food to steer them to and/or away from models with lessor profit margins.
That is true, but normally they don’t get a say in whether there is a totally new engine in a model.
An engine with a short life because it was replaced with the 2.7 DFI unit after only 5 years.
I can only assume it shares a lot of its architecture with one of the other engines, but I don’t know which one.
ETA: it seems the 2.9 is actually a variant of the 2.7 DFI motor. It is the MA1.20 in 2.9 variant and MA1.22 in 2.7 variant.
So it seems like the change to DFI was planned early, but maybe wasn’t ready for the 987.2 so they stretched it slightly to get the power target maybe?
