510 Weight notes
(by Mike Spreadbury and compiled
e-mails from the 510 list)
|Here is a bunch of data that I have collected over the
years talking about various weights of 510s...
510 weights are pretty funny. The FIA papers for the 510 four-door sedan state that the car weighs 1907lbs. (FIA recognition number 1493). Another set of FIA papers (5397) state that the 1800SSS version of the 510 (four-door) weighs 1929 lbs. According to the March, 68 Road & Track road test for a four-door sedan they state that the vehicle weight is 2130lbs. The "bible" (Hot to Modify Datsun 510 610 240Z Engines & Chassis) says that a stock two-door weighs 2042 pounds "less spare tire, jack, wheel covers, outside mirror and carpeting."
Which is correct? Well, I too have had many different weights with my 510. Let me explain, When I first weighed the car (the 2210 pound weight) it was with an empty tank, no spare tire, or jack but with the VG30 with the stock ZX 5-speed. This car was stock in every other respect. No big wheels, no big brakes, no big differential, no roll cage, just a totally stock two-door with a V6. This weight was done at a local truck scale.
Last summer, before the turbo engine or roll cage was installed, the car weighed 2342 pounds. This was with the big brakes, R200 diff, big 16" wheels, and Recaro seats. This weight was also done after the double a-arm modification was done. This weight was done with Steve Epperly's corner weights and is considered very accurate.
Last fall I weighed the car, with the new full roll cage, and the turbo engine, and ¾ tank of gas and it weighed 2440 pounds. This weight was measured at a truck scale in Eugene.
So, what is an accurate weight? Great question. Consider the differences in brakes, wheels, differentials, rollbars/roll cages when you decide on the final numbers. Note: VG30ET complete weighs 392lbs. Anyone want to share their 510 weights for comparison?

That's 95lbs for those of you unwilling to do the math.... My car, empty trunk, full tank, L20b, 200sx trans, exactly 2100 lbs. Probably 20 lbs of thick battery cable from front to rear. 2 door. Oh yeah, Panasports also.

Let's see, add a VG30, tyhat's 1971#, then subtract for the fiberglass stuff and add aluminum wheels instead of the steel I had on when I weighed it and I bet I can get to 1900#.
From Ted Hedman; For the weight conscious Bluebirds out there- Several years ago I had my car weighed on a set of Ruggles race car scales. It was a '72 2 door with L20b (DGV carb and stock manifolding), 2" exhaust, 200SX 5 speed, stock interior w/ rubber mats, 4 speaker stereo w/ 100W amp, Turn 6 F&R anti-sway bars, 13x6 Enkies with 205/60-13 tires, empty trunk (except for battery) and a ¼ tank of gas. The car weighed 2205 lbs without driver.
The following weghts are listed in my '72 510 Factory Shop Manual for USA/Canada Models:
My guesses on where the extra weight was in my car versus the standard 2-door 4 speed weight of 2050?
factory 2 door 2050 lbs (with spare tire?) my car (theoretical) 2192.5 lbs my car (actual) 2205 lbs (w/o spare!) difference +12.5 lbs, uncertainty +/-25 lbs?
From Dennis Hale; Michael brought up the subject of car weights SO here's mine: Pinkie weighs 1868 lbs with 75 lbs of ballast, JFZ brakes, plastic nose and plastic windows, 1800cc engine, R190 Diff, Roll cage, 3 gallons of gas, 13 X 7 wheels. The Bluebird weighs 2150 lbs with the 215 V-8, Muncie trans, plastic nose and windows, stock brakes, R180 Diff, rollcage, 13 X 10 wheels, and 3 gallons of gas. Unfortunately this car is classified with 1500 lb Lotus based stuff, like that is its' only problem....
From Mike Masson: We have a truckstop on I5 South in Everett WA with 2 State certified scales next to each other so you can get front to rear weight as well as overall weight. I weighed my LZ2.2 72 2door with 280ZX 5spd, 280ZX coilover struts and brakes, R160 LSD Legacy diff, aluminum finned drums in back, Sentra SER Seats front and rear, but otherwise stripped interior (no carpet or floor mats) and now for the #'s.... 1200lbs Front 940lbs Rear 2140lbs Total

Dave Carroll wrote; While I was doing my VG swap, I dug out
the digital scales and weighed the motor coming out of the car(L18SSS), the motor going
into the car(VG30E), and a bunch of stuff that was laying around the shop. Keep in mind
the differences in engine accessories on some of these.
