That's not too hard, just fully modify with turbo.
Run SuperSoft tires, since there is no tire wear in that series.
Run these settings.

The full-race transmission I only altered slightly as it's pretty good, it's already Auto Set at 22. Drop the final drive ratio to 3.600, and drop the 6th gear ratio to .935 so it tops out at about 173mph.
I was turning 1:44 sec laps on Tokyo 246 with this set-up. I also tried it in the Type-R meeting with Medium tires and, by the 3rd lap I was leading by over 10sec.
