I highly doubt it. My 83GSL with a 13bt in it was 2600 with it guted behind the seats and me in the car. I'm230 so the car was 2360. I'd like to hear from some1 else who has actually weighed their car. And I have a Momo Corse seat so that's lighter too...

There is some Norweigen chap who has their car down to like 1600lbs (or something), with an insain roll cage in it. I found it on google once. It is a FB to die for. The roll cage has to be really heavy, it is very elaborate. The car has fiberglass hood and front fenders formed as 1 if I rember corectly. It has lexan windows everwhere. I have no doubt that you could get any Rx-7 down to 2000lbs with out replacing any boddy panels.
You just have to really gut the sucker.

as you will be able to tell everything interior was left on, I have a 12a NA as oppose to a 13 B with all the turbo stuff which can quickly add up a hundred or so. So 2000# i can see that no problem

Mine weighed in at 2450 with a big stereo and full carpet and stock interior. and about 1/2 tank of gas. Now my engine is out and my turbo is coming this week so then ill weigh it after i get the turboed engine back in
My 1979 GTU road racer currently weighs 2080 pounds; I have had it down lighter in the past. It has a very heavy, very rigid cage in it, and it has a G-Force GF-5R transmission that weighs 50 pounds more than the Mazda transmission. Naturally aspirated engines are much lighter than turbo engines; I have a peripheral port engine.
The first few hundred pounds are cheap and easy to remove from a first gen, then it starts getting very labor intensive and very expensive. At the stage I am at now, it is now costing about $50 a pound to replace a part with a lighter one. I have 'glass front fenders, nose, hood, rear fenders, and lexan windows. Ever time I do a lightening/modifying project, I have carefully saved each scrap of material removed and weighed it, and compared it with the replacement race part.

2750 on a 1985 GSL-SE

My ITA car weights 2325 lbs with a 200 pound driver, minimum allowed weight is 2280 wet. My EP car used (may it RIP) to weight 2150 with same driver, minimum allowed weight is 2050 with stock transmission. The car I'm currently building will have all the lightening tricks available and I hope it comes in at 2100 with me at 175. Going drycell battery and will try no alternator as well.

The 84-85 GSL-SE is the heaviest of the RX-7's, while any GS is probably the lightest without the sunroof. The GS curbed at about 2360lb while the GSL-SE was close to 2500, in stock form. Any modification will affect the weight in some way. Directfreak's car is a GSL-SE with full interior, full roll cage, heavy ford 8.8 rear end, and all the parts for the turbo, which in themselves are heavy. 2700lb for a car like that is pretty good IMO. 2200lb seems to be the easy number to get to. Just strip anything heavy you can off the car. Its getting past that that is the hard part.
