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.

Jimmy installed an '05-spec 3.6 with the X51 Carrera Power Kit, taking option 1 and building the interface himself.
Leading evidence: 'Install '05-spec 3' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Install '05-spec 3' (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.

Sorry to hear about your motor. Do you know what it was that failed?
I'm not sure you can swap in a later 3.6 but it can be rebuilt into a 3.6 by Flat Six Innovations.

Charlie, sorry to hear about the engine! Having faced this choice myself, I found that installing a 3.6 in place of the 3.4 is quite an involved task, as the engine's interface to the instrument panel and throttle is completely different.
The 3.6 uses a data bus, while the 3.4 has an 'old fashioned' wiring harness--so the tech will either have to fashion an interface between the existing controls and the ECU, or replace much of the guts of the instrument cluster and throttle. Either choice is so sophisticated and tedious that a few very good factory techs I know were doubtful that it could be done at all. Almost needless to say, I certainly didn't want to approach the task myself, even though I've done almost all my own maintenance on Porsches and others for over 30 years.
That said--it can be done, and was on my car by Jimmy Hays, a Porsche Gold Meister tech, current PCNA tech rep for the southern US, and all-around Great American. Jimmy installed an '05-spec 3.6 with the X51 Carrera Power Kit, taking option 1 and building the interface himself.
The results, especially on the track, are eye-popping; only downside is that choosing the X51 will mean that--if you decide to go racing--you won't be in Spec 996, but in GTB where there are usually few folks to play with.
So, 300 ponies out of the 3.4 sure isn't anything to sneeze at--but if you can find a tech with the brains and the guts to take on the 3.6 mod, you will have gone from driving a very strong car to driving an incredible one.
