How much does your S30 weigh NOW.

Recommended Posts

Gents-

My 260 (late '74 model) seems to be a little on the porky side, too (2810 lbs w/o me)....but it doesn't surprise me, considering the way she's currently fitted out (weekday DD, weekend play-racer):

- iron-head SBC w/ TH350, mini-starter, aluminum water pump, aluminum intake, block hugger headers

- Autopower roll bar

- full interior, w/ Honda Prelude seats (fairly lightweight)

- street wheels & tires

- steel flares

- half-tank gas

- bumpers removed (saved 90 lbs!)

 

I drop 70 lbs immediately when putting on the race wheels.

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.

Mine is 2,300 without me in it. It's an inter cooled L28ET swap in a stripped interior (with sheet metal dash instead of factory one) 1973 Z.

 

My 72 with a 2.8 NA, most interior removed, roll bar with backstays, all glass still in, gutted dash just scaled at 2254.

Last time I had mine on scales it was about 1983 lbs without driver, and with a couple gallons of gas, it had the full dash, but no interior plastics, all sound deadening removed, the seats replaced with Kirky aluminum shells, no side glass, rear glass replaced with plexy, and no lights.

 

It has no lights now, just brackets to hold some switches and gauges, the harness has been removed, and I ground off many of the now useless brackets for holding stock interior stuff. I need to get it on the scales again eventually to corner balance it.

 

This is where I have to get....vintage rules allow me 1950lbs so I have 300 to go.  I may have to PM you for some help moving into your neighborhood.

I've kept track of the weight of my '77 280Z.  In stock form with the L28, 5-spd, R200, MSA type 1 ground effects kit, and 3/4 tank of gas it weighed 2,800 lbs - evenly split front and rear.  Same set-up after the LS1/T56 conversion it weighed 2830 lbs - 1,400 on the nose and 1,430 on the tail.  After doing the full interior - dynamite, leather, house carpet, front and rear sway bars, 4-pt roll bar and a 7 speaker 500 watt sound system the car porked up to an even 3,000 lbs - 1,440 on the nose and 1,560 on the tail.  These weights were all taken on the same certified truck scale.  During the conversion I had corner weights taken and they totalled up to the same front and rear as the truck scale.

My 73 weights 2506 weighted on the scale at US 13 dragway and the DOT truck scale nearby. Both with a half tank of fuel, both weights within 10lbs of eachother. Other weight was 2516.

 

L28ET swap, T5 trans, R200 Rear 15"aluminum wheels Stock interior, aluminum radiator, intercooler, exhaust also does have a muffler on it (pretty dang heavy one), agm group 24 battery.

 

Stock body no mods or flares etc, no cage or roll bar.  I wish I had weighed it right when I bought it.

Just picked up a 11/70 240 bare chassis - has front suspension/steering rack/column/wheel & rear suspension/r180 diff - 14" steel wheels with tires - nothing else.

No doors, hood, hatch, interior or any lights or wiring.

 

1085 lbs.

 

I am thinking of transferring everything from my 260 race car to this chassis to trim down my bulky 2350 lbs.

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, 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.
