I've seen a range from 1000 lbs up to ~1700lbs for our 4-wheel'd versions. Track car vs Street car; Book chassis vs 442 or?; BEC vs CEC, I-4 vs V8. We are a wide focused group.

My street car book chassis with RX-7 donor components (engine, trans, diff, uprights, brakes, wheels, etc....) came in right at 1400lbs. No real effort was made to save Lbs. Heck, I added lbs afterwards just for the hardtop.

As a matter of fact, I wasn't looking for the lightest, fastest thing on the road. If I were serious about that, I'd drop 40 lbs. I enjoyed just building it and now enjoy driving it.

DANG! I had no idea you weighed 500#. You wear your weight well.

Plus 4 McSorley plans as a starting point for the chassis, Toyota AE101 4AGE engine, early Corolla T50 Trans, much modified Miata rear sub frame w/Celica GTS diff. Weighs in at 1,412 lbs with 6 gallons of fuel and all other fluids.

Scuttle is pretty heavy with 18 ga steel skin, floor pan is 16 ga steel. Not much effort to save weight. It's just a street cruiser, not a race car.

Mine is 1294 with about 2 gallons in the tank. Book frame with a 3.0 v6 (all iron), Mitsubishi 5 speed, and toyota rear axle and front spindles/brakes. I don't have a windshield or heater, but didn't really go to any great lengths to keep the weight down.

my deman SR27 is 1346 lbs in running condition with 1/2 tank SR20 DET engine and transmission, Miata rear diff and spindles (only missing mirrors and deflector. I had a fiberglass hood that will be replaced by an aluminium one) I had some weigh saving effort, DBA500 brakes, willwood calipers, aluminium wires, carbon fiber driveshaft, all can bus body control and gauges (aim dash and isis body control unit) light weigt battery, cromoly roll bar and light weight forged mags aluminium flywheel and pulleys


My fathers car (a bono bonate bought here on the forum) its a 7ish looking frame with a unusual suspension point and the engine is sitting wayy back (flywheel is beside the ankle of the driver). it has a 12A rotary with matching transmission. Datsun rear diff with custum rear hubs and triumph front (with heavy cast disc) no weight saving effort really.. and we got to 1376 lbs with a bit less gaz than mine (1/2 tank of a small fuel cell) i was expecting it to be lighter than mine honestly...

My book frame street car with MGB running gear comes in at 1560 lbs. When it came to building the thing, I spared no steel. Also, the MGB running gear is massive. So I have to think this is the upper limit on book frame builds.

I think I've seen numbers somewhere that showed the MGB 4-cyl weighed more than the Rover (nee Buick) 215 V8. I can testify that it's one heavy l'il engine. Tough, simple to work on, fairly reliable... not a bad choice overall... but heavy...
:cheers:

1045pounds on the road with approx. 10litres of fuel in the tank. If I changed my wheels from 17in to 15in then I can save another 50 pounds. Each of my 17in wheel and tyre weighs 50pounds.

My custom mid-engine build using GM LS2, Muncie four speed mated directly to C5 Corvette diff, and all C5 Corvette suspension pieces weighs 2120 lbs in its current configuration. It got as high as 2440 lbs with a turbo, iron block engine, and automatic.
