tube80z Posted February 21, 2014 Share Posted February 21, 2014 1970 240Z, SUs, light flywheel (weighed 369 lbs.), 4-speed, R200, full cage. No interior, 25 lbs. battery, very light wheels/tires/brakes (13 inch). 0.125" lexan windshield, FG door skin, one-piece FG nose Weight with 3 gallons of gas was 1850. I had probably another 100 to 125 lbs. that could have been removed. Keep in mind this is an autox car and not a track car. It's very easy to add weight in wheels, tires, and brakes. Changing to 15 inch wheels and tires added 75 lbs. Cary Quote Link to comment Share on other sites More sharing options...
richie2619 Posted February 21, 2014 Share Posted February 21, 2014 According to my JTR manual, my 78 weighs 2750lbs. With the LT1 eng, Tremec TKO 3550 trans and Lakewood, steel bell housing, I added about 80lbs to the car. (Aluminum heads, intake and radiator). Pretty fair trade-off, since I added an additional 250 hp over the factory eng! Quote Link to comment Share on other sites More sharing options...
roger280zx Posted February 21, 2014 Share Posted February 21, 2014 Cary, I'm assuming you have composite body panels other than the gnose and door skins. Or is the where some that other 100+ pounds will come from? Quote Link to comment Share on other sites More sharing options...
Jon 74 260Z Posted February 21, 2014 Share Posted February 21, 2014 light flywheel (weighed 369 lbs.), You have a flywheel that weighs the better part of 400 lbs???? Quote Link to comment Share on other sites More sharing options...
tube80z Posted February 22, 2014 Share Posted February 22, 2014 You have a flywheel that weighs the better part of 400 lbs???? That was the complete engine. Quote Link to comment Share on other sites More sharing options...
tube80z Posted February 22, 2014 Share Posted February 22, 2014 Cary, I'm assuming you have composite body panels other than the gnose and door skins. Or is the where some that other 100+ pounds will come from? One-piece nose, full doors, and rear hatch were all FG on the car. The rest of weight was lighter components. Rear diff changed from an R200 to an alloy Ford 8.8, steel driveshaft changed to an aluminum one. And so on and so on. I helped a friend put together another 71 240Z that was 1840. It used many of the same parts but had a Rebello KA24 and an R180 rear end. Very fast but very peaky. Quite a few of my friends are laughing at me when I told them I'm going to have a sub 1900 lbs. LS powered autox car. Cary Quote Link to comment Share on other sites More sharing options...

tube80z Posted February 22, 2014 Share Posted February 22, 2014 Is that with safety equipment for racing? This was an autox and hillclimb car. It had a 8 point cage, belts, window net, and 5 lbs. fire extinguisher. Quote Link to comment Share on other sites More sharing options...

repenttokyo Posted February 8, 2018 Share Posted February 8, 2018 2250 lbs. 78 280Z with full interior, race header, no bumpers. TTT coilovers and assorted suspension gear, 15-inch Rota wheels. Quote Link to comment Share on other sites More sharing options...
rturbo 930 Posted February 8, 2018 Share Posted February 8, 2018 That doesn't seem right. A 78 280Z with no bumpers that is otherwise mostly stock should weigh about 400lbs more than that. Quote Link to comment Share on other sites More sharing options...
repenttokyo Posted February 8, 2018 Share Posted February 8, 2018 (edited) People keep telling me that, but that's the weight I pulled off the NASCAR scales at New Hampshire Motor Speedway at one of my track events last year. The same scale gives me an accurate weight on my CTS-V, too. Edited February 8, 2018 by repenttokyo Quote Link to comment Share on other sites More sharing options...
rturbo 930 Posted February 8, 2018 Share Posted February 8, 2018 Honestly, the first thing my mind goes to is that the VIN is from a 78, and somehow made its way onto a 240Z body. If the scale is accurate, and the car is as you described, there's just no way it should weight what it does. That would be a good number for even a 240Z. There was someone here a while back with a car in the reverse situation. Early 240Z VIN, reshelled with a later 280Z. Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted February 8, 2018 Share Posted February 8, 2018 (edited) My '78 with mostly stock components, L28ET and BW T-5 transmission, full interior, full 3" exhaust and no bumpers or spare tire was 2600 lbs.

Gollum Posted March 4, 2019 Share Posted March 4, 2019 I feel like we've got three or so of these threads rolling around, but this one at least has semi-recent postings. I only trust the scale +/- 20lbs, but my last weigh in was 2280. 1975 280Z Gutted doors (no glass, factory bracing still) No interior other than OEM seats No dash No spare No bumpers MSA Type 1 fiberglass air dam L28ET (no oil cooler) S130 5 speed, I think an '81 R200 diff 3" exhaust, no cat, straight through muffler No AC No HVAC/Blower/anything Hey, I still have wipers! I have another 100lbs easy to remove too, I think. Going to replace the rear glass with plastic eventually, and my whole front end is still steel. Will replace hood eventually, and since I deleted the HVAC I need to get a smooth cowl panel, and might save a few ounces there. I'm also running a common group 53 lead acid battery, so there's 15-20lbs of weight savings there if I wanted to spend the money. Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted March 5, 2019 Share Posted March 5, 2019 On 12/16/2011 at 3:04 PM, BluDestiny said: I know this is for S30;s, but I weighed my s130 base model coupe that I've been working on and it came in at 2470. Specs: Full 20 gal tank, all fluids no Sound deadening, no spare tire or tools completely stripped save for the dash, center console and 2 sparco tec seats (40lbs for the pair) No AC lines in the bay( still have under the dash stuff) No power windows, or power steering s13 coilovers, s13 alum radiator. 6-2-1 headers w/o cat and shaved n42 intake No front bumper( have a fiberglass Gnose on) I didn't have my whale tail on, but it cant be more than 30 lbs. I had an SR20 Swap done on my 280zx by Touge Factory in Chicago about 2 years ago. They put the car on a scale when they were done (they got the car without an engine in it) and it was at 2460lbs. All the same things as above apply, except I had some roller steelies on the car, it did have a front bumper since my Gnose was obliterated by a brick on I-10, and I did have my whale tail on.
