Assuming you leave the last engine upgrade, looking at the upgrade tree the only other single upgrade you could leave is exhaust 3. I tested this and it comes up 0.1 short. Any other option would require removing two upgrades (1 gold and 1 R$). So short of testing every combination, I'm fairly sure 4444344 is the one. It has also been confirmed by this user (https://rr3.fandom.com/wiki/Honda_NSX-R_Championship#comm-311522)
