Application determines longevity.
Nikasil can last 200K+ under the right conditions but will the rings.
The ridiculous rod length to stroke ratio of the 3.2 creates excessive side loads on the piston. This causes rings to wear more quickly vs say 911SC . I would be amazed to hear that a 3.2 with 120K would be stingy with oil.
Now my Tundra with 350K doesn't use oil but an air-cooled 3.2 with 120K....I'm skeptical.
