I would like to agree with you that, 2m45.43s MIGHT(Not) be legitimate for a 171 Civic,
I did this map with a 399 P1, for 2m27.87s, which put my next challenge at 2m26.67s. Yes, go ahead and call me suck. That is a less than 20 seconds lead with 4 laps, meaning my 399 P1 is faster than the civic for 5 seconds each map, doesn't sound anywhere near legit.
However, since I by chance had a nearly stock Civic in my garage, I took it out and tried it. With performance level of 176, the fastest I have achieved was 2m58.xx seconds., which I did have some flaws, adding them up may give me another 3, 4 seconds faster time, yet, it is still around 8 seconds slower than the 2m45.43s speedlist record, makes it 2-3 seconds slower each lap. That doesn't sound too bad I assume, since I still have a lot of details along the run to be perfected.
If it is not by using glitch/cheat, that is one hell of a record to be done, makes me wonder since when does everybody become so competitive.
If it is done by glitch that make you use a upgraded car without telling the correct performance index, I would like to assume the car would have the PI of at least 230.
