Assuming a specific gravity of between .69 and .75 (i've seen different numbers in the brief lookup that i did) for gasoline. That would mean a full gas tank (15.9 gal) weights right at 100 pounds. So a full tank would put you closer to honda's number, 2866 lbs.
Sounds right on. My 92 Si with JDM swap was 2750 without me in it with quite a bit of gas though. Full interior also.
Also...I doubt you could run a [email protected] with 180whp. 14.3s are usually at around 97-99mph. I'd say more along the lines of 14.5. I did run a [email protected] once though. Ever since the hesitation my top end is DEADDDD.
I've weighed my car once at a truck weighing scale when no one is around on weekends. The scales are still hooked up and free. The digital readout on the screen said my lude with me in it and a half tank of gas was 1360 kg ~ 2992 lbs. That sounds fairly heavy compared to your weights. It was a full interior with a 12" sub.
