that is not quite right : As tested by motor Trend in 1984 a Top of the line Turbo was 2810LBS in the USA.
The SEv6 tested by Motorweek was about 2900lbs -- This is the same weight as the 2litre RS-X in japan if fully loaded.
until the model change over in the middle of 86 :
A Base R-L (1.8 carb) was 2150 lbs (solid rear axle)
A base model RX-E Coupe (1.8 litre EFI) was 2250 lbs
An RX-G coupe (1.8 sohc turbo) was 2400lbs
at least according to their sales brochures
A Base model Coupe GL in the states was in the 2300lbs mark with mechanical timing control and Solid Axle.
It was about 2450 with Electronic Timing introduced midway through 1985 production which also made independent rear standard on the coupe along with using a heavier duty transmission.
S12's and S13's have the same basic unibody and frame rail (also nearly the same as an s110) and they are all floppier than a wet noodle, including the missing chunk on one of the frame rails.
Brakes were bad sure, the s12 turbo took 115ft to stop from 60 but it also had narrower tires than the S13 which did the same stop in 107ft, 7 years later with ABS. But how do these numbers realistically stand up ?
A Z06 C7 vette stops from 60 in 92feet. For the average driver, that difference is marginal at best, especially here in the states where people drive things like Ford F350's that take 220+feet to stop.
in the USA a base FC was nearly 2700lbs, and competed with the base model 300zx, also around 2700lbs, the top of the line turbos of both with all options being above 3200lbs.

Its not fanboyism, by todays standards, all of these cars are terrible and are beaten by the Camrys 90 year old women buy.
Also OP is way over paying if he goes after the CL ad one. My running SEV6 with mint interior was $1400 and it just had new calipers, pads, and rotors put on by the dealership. With a blown CA20 you are basically buying a shell which is about 500 scrap price.
