If I remember correctly, late 03+ cars use a clip at that joint, earlier cars use hose clamps.

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.

The EFI system will be different, as will the ECU module. There are different engine control aspects with a manual vs an automatic, sudden off-throttle, for instance, the engine w/automatic will have a different provision for this vs....
But "core", short block, will be the same.
You mean long block. Short block is without the heads and long block is with it.
If you check on car-part.com, it doesn't ask the type of trnasmission. If it mattered, it would ask.
It is the same engine. Porsche consolidated replacement engines in 2000. Only option for 2001 and earlier is e-gas vs. non-egas. There is a TSB which covers what does and does not get plugged for vac lines. Manual trans tie wrap the wiring for the ATF switch-over cooling valve. BTDT
Pic of housing Txhokie mentioned (MT housing swapped for core return). Second pic is old Tip housing transferred to shiny new factory replacement. You will just need to swap your MT housing to the new engine. Very simple, only a couple of bolts.
The cooling elbow posted is a year change, not related to transmission. If I remember correctly, late 03+ cars use a clip at that joint, earlier cars use hose clamps.
Alternator pulley (decoupling on manual cars) some engine mapping and a vacuum line are all I recall to be different between the two motors.
I have everything to replace over to the new engine. I mainly just need the block but I like the idea of having a extra block, to be sent to ln, and a set of heads. I'm a parts hoarder lol
