76-79 - Jekyll & Hyde turbo kick, with a waste Gate spring set at 0.8 bars
76-79 - 3-spoke leather steering wheel
78-79 - 3.3 liter, intercooler, more power and larger fuel head than 86-89s
78-79 - heavier than the 76-77 but lighter than the 86-89’s
78-79 - leather dash
79 - only year Porsche won Le Mans with a RSR Group 5, 935 (homologated
930)
79 - last year of the true “930” VIN
78-79 - only 2 years Porsche built a Turbo with a Intercooler but no Catalytic
Converter. After 1979 the turbo did not pass US NITSA emissions.
78-83 - are a bit more torquier then other years.

Just to add a little bit of fun reality to the above
:
1) All years utilized the same turbocharger (the horrendous, 3K 3LDZ) and ignition system (same fuel system, too, except for the later Lambda fuel head that does not affect acceleration), so they all have the same, shiity, "Jekyll/Hyde" throttle response in shiity, stock trim.
2) Where do you get the "more power" than later numbers figure? Nothing about the 78-79s would indicate superior power over the later models, and in fact, the thermal reactors, and accompanying atrocious turbocharger plumbing (much improved in later years) would indicate inferior engine performance.
3) The non-Lambda fuel head of the earlier years is not bigger - the metal fuel lines to the injectors are, but the smaller lines on the later years have been dyno proven to not choke fuel supply. That fuel head is made of cast iron (susceptible to rust, both inside and out), whereas the Lambda head is cast aluminum, and the iron head uses a metal diaphragm that is known to become dempled in the event of fuel pressure spikes, where the rubber alloy diaphragm in the Lambda head does not dimple (it can degrade over time, however, and would need to be replaced - much easier to re-seal, in that event, than the metal version).
The cast iron head flows a little more fuel in stock form, but the Lambda head can be modified to outflow the iron head, regardless of mods done to the iron version (dyno proven).
4) 78-79 did not have cats, but they did have thermal reactors - which do you think is more of a performance and engine longevity detriment, and which is easier for an owner to change if he/she/it feels like it?
5) Not so, about the "true 930 VIN" - the later 80s vins have the "930" designation in about the middle of the number sequence, and the "0" is replace with an "X" - an "X" is far cooler than a "0".
6) Where do you get the "more torquier" idea? The build details say otherwise (especially the already mentioned turbocharger plumbing).
