Cool So I weighed my FB tonight...
In the middle of a *ahem* "sporting drive" I happened upon an easy way to hit the truckstop on I-5 by my house, so I figured what the hell. Stock 1983 RX-7 GSL with power windows/mirrors, cruise, A/C, glass sunroof, and full emissions intact with a full tank of fuel (minus about a gallon from the station to the scale) and the spare, jack, etc still inside.

2,650 Lbs.

Considering I weigh about 235 at the moment that's not bad! So 2,415 for an all-stock, fully-loaded FB, with a full tank. Figure I run it at about 1/3 tank in the autocross, plus no roof/spare/jack/spare oil/etc. Gas weighs 6.15Lbs/gallon, so take out 60Lbs of gas, and maybe 25Lbs for the roof/spare/etc and it's maybe 2,565Lbs when I autocross.

I'll re-weigh it as I take stuff out (A/C, emissions, exhaust, interior stuffs). I'd like to get it around 215Lbs out to bring it to 2,200 without me and under 2,500 with me. So figure the A/C stuff weighs quite a bit, same with the smog pump and the factory exhaust manifold. Also relocating the battery and replacing it with a lighter one, also going to a lighter interior insulation and seats. Should be doable, right?
