The 965 has standard many of the mild upgrades that are performed on the 930 such as the K27-7200 turbo, larger intercooler, and greater boost level. The transaxle should also be considered as it is a 5spd with lower gearing than the 930 4spd.
Typical upgrades for the 965 would be deleting the cats and adding a more free flowing exhaust system and changing out the K27-7200 turbo to a K27S, K27HFS, or some non-K27 brand that can be adapted to fit.
The ignition system on the 965 is also superior to the 930. Electronic controls can be modified.
The fuel systems on the late 930 and 965 3.3L engines are very similar with the WUR being more complicated along with the Lambda system computer or turbo control unit. These are often deleted and optioned with the modified fuel head and adjustable WUR such as the 930.
Basically anything that is done to a 965 can be done to a 930 as the engine platforms are identical. Apparently Porsche had a lot of 930 engines left over in 1990.
