On my old GXL, I took out the AC, PS, emissions, cold start, most of the undercarpet mats, jack and spare. I replaced the dual exhaust with a single, installed an aluminum flywheel, race seats, aluminum hood and light wheels. I sold it to a friend, who put it on a dump scale which showed 2420lbs with a 1/4 tank.
BTW, the stock exhaust is HEAVY!! Stock catback was 70lbs. The JIC single we put on was 18lbs. (It was a little loud, though.) :D

granted i havent stripped anything but with the LS2/T56 combo i weighed in at 2800 lbs on the money with gas and full interior,, I was always wondering what rotarys were weighing in at and what was capable. glad i came across this thread so far good info guys

ooops meant LS1 not LS2

continuing this old thread. i weighed my car recently and it was 2920lbs O.O . S4 TII, power windows, sunroof, full interior, a/c, p/s. spare tire removed, 18in wheels (275 35 18 rear), 4inch down pipe, 2.5 rb dual exhaust. big borg warner turbo. full tank of gas. my car is a fatty..
the funny thing is i had an almost perfect 50/50 weight distribution with the back weighing 40lbs more! im assuming a half tank is a perfect 50/50 =D

the lightest FC i've ever seen was 2350lbs with cage, this car had everything, front halfed, FC door skins, CF hood, CF hatch, lexan, 15" 9lb rims, you name it.

my car is currently at 1200kg (2650lbs) with full tank and half cage.

I got to put my car on some scales recently, and since I'm staring at my data page on my pin-board...

91 Vert: 2966

The minus:
Airbag system removal (airbag/computer/battery)
No A/C (evaporator still in dash)
Lightened steel flywheel
Cobra Imola driver's seat
Several interior panels removed
Coilover suspension
Spare tire removed

The plus:
Rollbar with single diagonal
BBS RGII 17*8/9 245/255
Mazdatrix triangulated strut bar.

Corner weights (didn't play, just measured)

LF: 772 RF: 728

LR: 736 RR: 730

My 87 FC started as an automatic base model with manual steering/manual windows/no sunroof/manual mirrors, got 5-sp/5-lug swapped, front strut bar, RB streetable header+presilencer, stock catback [when weighted], Skyline R32 GTS-T wheels, front strut bar [I think it had it at that time..], S5 non adjustable seats, cone air filter with the long part of the snorkel still in place, AC compressor and tubing removed [condenser and underdash pieces were still in place], still had the aluminum 4-lug spare in the back..
and it had ~3.75Gal of gas in the tank when I weighed it]
it came out to 2550LBs on a truck weight station scale. [I was not in the car]

mine is a totally STOCK 1987 GXL with ABS. steel hood, steel spare.

2880 lbs with a full tank of gas, no driver

10ae- 2900 lbs, 3/4 tank of gas, full interior, stereo system. Waste Management scales

88 gxl with 1/2 tank of fuel and no driver was 2700lbs according to the truck scale. this was weighed as i drive it, spare tire, tool kit, bottles of oil and water.

2580lb on a junkyard scale...10ae. most amenities removed...nothing obvious by looking inside the car.

mines weigh over 3200 but i have 18 inch chromes rims(getting my new 16s today) and have 2 kicker L7s in a costum(heavy) box.
But i have considered taking it out but realized that it really wouldnt matter since mines not a track car.
Still thinking of how nimble my near stock 300zx was with just intake and cat back makes me wanna lighten her up some.

16"s..Aluminum hood... no ac ps or air pump... no rear bins.. base model... when I weighed it it had quarter tank door panels and. Carpet...

2425
Lf 659
Lr572
652rf
542rr
Cross 50.5%

Now I have no carpet ,no door panels ,no headliner, no interior plastics..I added a fire extingusher
And Love it!!!! I don't have any other numbers but in guessing 2,350.

Sorry double post

i pulled the spare and put an AL hood on mine for a while, it didn't make it to the scale, but i imagine it lost 50+ pounds, and i could tell

haha I forgot about this thread. I've weighed my car and it was 2680 with a half a tank of gas

1986 sport model

yea i think i just lost like 100lbs changing from 18inch chrome fat tires to enkei 16s,
and another 100 losing parts and pieces i didnt need inside the cabin such and coolant and spare oil, and spare tire, havent drove it yet but it looks sexy now

just drove it.. wow biggest difference ive felt in a long time. so nimble and quick

See my post above :nod:

I had some weight reduction done to my 10th AE and it went from 2710 when i purchased it to 2525 at the last weigh-in at the track.

Removed all:
PS system (hoses, bracket).
All AC system (hoses, condensor).
All cruise control system.
All heater system (hoses, blower, vent ducting).
All stock sound system (all speakers, head unit).
Front and rear bumbers under bumber facia.
Four metal "tie-downs" and bolts under car.
Stock flywheel replaced with ACT lightweight.
All exhaust system replaced with RB downpipe.
Spare/Jack.
Removed padding under carpet and replaced carpet.


Other little things here and there.

I have an 88 gxl with ps and ac delete. No carpet at all. No storage bins. Converted to manual windows and mirriors. Have an alluminum hood.When I weighed my car the ac and heater stuff was still under the dash. It weighed in at 2510 with half a tank of gas without me in it with my backpack and books in the hatch. Since then, I've gutted behind the dash, ditched the door panals and center console, converted to side draft carbs which ditches the heavy intake manifold and running msd blaster coils which are lighter than the stock coils. I changed to lighter wheels not sure of weight. I ditched the rear wiper. I'm planning to weigh it again. I know I've easily ditched over a hundred pounds since the last weigh in. I'm shooting for around 2350 with half a tank before I invest in a carbon hood and fiberglass fenders. I'm planning an all motor pp build with rx8 rotating assymbly. I picked up a 8lbs fidanza flywheel but not installed yet. Thas gonna shave 16 lbs off by itself. I'm also planning to pick up a mazdatrix alluminum driveshaft, that'll save an additional 7-8 lbs. My car is still street legal with the working sunroof.I'm going to be adding some weight back unfortinatly, I'm changine to true dual exhaust with two presilencers and mufflers to try to keep the pp on the street. It'll be a few weeks or so but I'll Let you guys know the new weigh in numbers once I make it back to the scales. I'll still be running the single exhaust still. I'm expecting under 2400lbs with half a tank.

Scaled mine at 2499lbs with around 1/3 tank of gas and me not in it. Car is a 90 GXL s4 t2 swap. Most everything is gone thats easy to remove. It would be lighter but has bed liner sprayed through out the engine bay and undercarriage.

Attachment 709068
Attachment 709069

supposedly bedliner is lighter than the equivalent coating of paint (primer, base, clear, everything)

of course you'd have to have stripped down to bare steel before lining it to have the savings

2325 lbs, with full race cage, full stock metal body work (aluminum hood), full stock glass. Almost empty on fuel.

17" wheels

S5 non-turbo

Stripped just about everything else out.

Weighs almost 600lbs less than my mostly stock turboII (ABS removed only)

88 base model with an aluminum hood, A/C and P/S removed, no emissions, full interior (but some sound deadening and mats underneath carpet removed), Odyssey PC680 in passenger's bin, no speakers or sound system, other misc removals = 2380 lbs with somewhere between 1/4 - 1/2 tank of gas and no driver.

87 TII with A/C / P/S removed, no emissions, full interior (not as much removed yet as on the '88), no speakers or sound system, Odyssey PC925 in passenger's bin = 2630 lbs with somewhere between 1/4 - 1/2 tank of gas and no driver.

Both weighed in at a rock quarry, one after the other. I'm just muy aggressive with the removals or the scale was a bit wacky, something.
