Weight obsession - part weights on S13

[Def]

I made the mistake of throwing my car on a local set of scales, and now I'm weight obsessed again. It came out to 2550 lbs with a half tank of gas, 1.75x0.095" roll bar, no interior from rear seats back, but full stock interior from there forward. No sound deadening. Bumper beams frt and rear, SR with no AC, lots of chassis bracing. Cheap fiberglass hood is the only thing to save weight, but I imagine my splitter/wing offsets that. Weight balance was 53.7/47.3 frt and rear.

So I've got some ideas of ways to lose weight, but I'd like to at least get an idea of the magnitude of weight loss possible. I cannot find reliable weights for these components, so if any S chassis gurus that really know the car inside and out(like Russ) would chime in with at least a ballpark, I'd appreciate it.

Components(all S13 hatch):

-HVAC blower motor(looks heavy, never taken it out)

-HVAC control flap/heater core box(I'd like to keep my heat, but if I can simplify the flaps with some cables I'd look into it to save some weight)

-hatch rear glass

-rear quarter windows

-rear bumper bar(stock)
