Okay, I see a lot of posts about vehicle weight and the differences between the various CX, VX, DX, and Si models.

I'd like to set this **** straight so nobody else is confused.

First of all thanks to Shawn Hayes here on H-T for hooking me up with the 1992 Civic sales brochure, which had all the specs for every 1992 Honda Civic available, meaning hatchbacks and 4-doors only since the coupe wasn't offered until 1993.

Anyways, here go the base weights as measured by Honda in 1992:

1992 Honda Civic:

CX hatchback: 2094lbs.
VX hatchback: 2094lbs.
DX hatchback: 2178lbs.
Si hatchback: 2326lbs.

So that's the weights of each vehicle STOCK.

Notice the exact same weight for both the CX and VX? This should dispell those "VX is the lightest" arguments. In fact, in theory would you not think the CX would be even lighter since the VX had light-*** alloy 13 inch wheels while the CX had heavy-*** steel wheels? This would leave me to believe a few different things:

Body for body (which matters more because you swap out the wheels anyways, I mean 13'' wheels, come on!) I think this may mean the CX is lighter still. The only thing I can think that would make the VX the sane weight but has much lighter wheels might be that the VTEC-E motor weighs more than the CX 8-valve motor.

Another thing is the gas tanks.

CX and VX has a 10 gallon tank, while the DX and Si have the 11.9 gallon tank. Keep in mind these specs are striaght from Honda, so regardless how much gas you've squeezed in your CX, VX, DX, or Si it dosn't matter. Honda probably only measures TANK volume, not the filler and what's already in the fuel lines, etc.

So you also see that the DX is 84lbs. more than the CX/VX. Why would this be? Here's what I came up with:

Bigger fuel tank - tank is steel, so bigger = heavier
Rear wiper/washer
More tar - seen it myself. DX has more tar than the CX/VX.
Side moldings - plastic, but still weighs more than the non-existent side moldings on the CX/VX
Rear cargo cover std. it weighs something, right?

That just might be the difference. Things like the cargo cover and tar, rear washer/wiper can be deleted to get closer to CX/VX, so it's not a huge deal.

You also see that the Si is one heavy PIG compared to it's other hatchback brothers.

One more hilarious thing here for you guys with Si hatches that say "coupes are heavy, that's why I have a hatch" which I see often, and used to say myself.

How's this strike you:

1992 Civic 4-door with manual tranny:

DX 4-door: 2275lbs.
LX 4-door: 2319lbs.

Why did I bold the LX 4-door weight?

Because it has power windows, doorlocks, cruise control, power steering, etc. and is STILL lighter than the Si hatchback! So what do you think of the coupes now? If the 4-door is lighter, what about the 2-door coupes? The DX coupe is a good deal lighter than the Si hatchback.

Don't get all pissy if you own an Si - I used to have one, but after getting beaten by others in CX, VX, and DX hatches with less whp I sold it to build up a CX hatchback.

So, does anyone else on H-T here have this kind of info on the 1994-1995 hatchbacks? I know they weigh more because they added another airbag in 1994-1995, and some Si hatches came with ABS too. All that **** adds weight.

One last thing to keep in mind here:

These cars were weighed BONE STOCK.

This means:

No A/C - was NOT std. on any hatchback in 1992
No radio - again radios were NOT std. on ANY hatches in 1992
Only Si had 2 mirrors std. Add the weight of a mirror if you got 2 on your CX/VX/DX
ONLY the Si had powersteering - the DX auto did too, but I didn't list that one. I listed the manual, which had no p/s
Stock wheels. VX had lightweight 13'' alloys, CX/DX had 13'' steels, Si had heaviest 14'' steelies with wheel covers

So think about all those things that we can take out of our cars to get the weight down. This gives you a basic idea of what your car should weigh with no A/C, p/s, etc.

Also think about what ADDS weight to your car. Stereo, SWAP, bigger brakes, swaybars, bigger wheels, strut bars, etc. So don't think your 1992 CX weighs 2094lbs. if you have 2 mirrors, A/C, radio, SWAP, etc. You might be over the stock weight.

What are your thoughts on this guys?

BTW:

Here's an old thread I started that listed people's mods and their weight on a scale, so check it out:

Hopefully people were being honest there.

Excellent post. My 94 coupe EX with full interior (del sol seats) minus the spare tire and jack w/ LS motor and JRSC was 2378 on the SCCA scales at the national event last year

SpiceyRice

Yeah, good information, thanks for the post!

broke1

this post got me wondering what my 99 ex comes in at. i guess i'll weigh it this week. then again i probably don't want to find out . damn that sun roof i never use

MGD

vx is still where it's at. Don't be jealous!!!!!!!!!

H22pwrd

Good info. Exactly why I'm on this site all the time and off the dean's list.

Aww man

i own a pig

singlecam screamer

hell my 94 Si with abs,and no ps or no ac with the h22 weighs in at 2480 w/o me in it,that's why i got a cx if i ever want to switch the h22 into the cx i can but when you compae the Si to the cx there is no comparison it's almost like driving a totally different car,but i guess thats the price you pay for comfort

lucas569

you bastard! **sniff* you think the Si is a fat pig!? imagine a 5th gen coupe? *sniff* someone call Jenny Craig pleeeeeassse! *sniff-sniff* lucas569 who feels like a fat cow now

Hondahatch4eva

are the 93 civic the same weight as all the 92 like 92-93 cx=2,094??????

Hash Browns

Instead of simply having base weights for cars by trim, why not separately weigh engines, transmissions, linkages and all other parts required for swaps as well. Once a completely different motor is put into a car, the curb weight figure no longer applies. On a smaller tangent, maybe people could stop calling Delsol VTEC's "heavy pigs" as stock curb weight for a 94 is around 2,450lbs. They're simply heavier than one would think, when looking at its size. The EG2 has all the amenities of an Si hatchback, other features and the B16 motor. I don't have a factual basis for this next statement, but a D series motor is significantly lighter than a B series motor, likewise an H22 is heavier than a B series motor and so forth.

So if people getting swaps now could beforehand weigh the motor/tranny/axles etc and then weigh the removed parts and put them here on H-T, it could give people an idea of what weight changes will be made with the swap.

Yay!

Mr. Thunderlips

nice job as usual tom...you should be a magazine writer or something...you need some type of profession where you can use these skills

B18poweredhatch

99 dx coupe
removed ac, from the front seats back is stripped, 99 b18c1, heavy *** rims on the back 2 wich weigh in at 42 lbs per rim with tire and 13 in stocks in front, c/f hood i weighed in at 264? with me. then again i weigh 290 something

cj7420

How can a coupe/4 door weigh less than a hatch? They're like 2-3 feet longer aren't they?

Maxi

carpoint.msn.com has reasonably reliable curbweight data. I've cross referenced it with several other sources (Car Guide and R&T) as well as factory data where available and for the most part carpoint's curbweights for model variants are accurate.

GokuSSJ4

damn there light ! cx and vx
thanks for the info

As most of you know I already have a car completely taken apart roght now. It is a 1992 CX that I had to strip to a completely bare shell in order to color change from red to silver - inside and out, engine bay, etc.

Here's the good part:

I have every single interior piece out of the car right now. I have a box with all of my tar and gunk that holds the plastic sheet on each door that hides behind the door panels. Hell the dash is still out too. I also have the heavy-*** firewall mat that hides behind the dash too. I took out the wiper motor (heavy), rear seatbelts, rear seats (of course), spare tire, basically anything you can remove from the car that adds weight to it.

I can probably get on a scale holding each part and see how much this **** really weighs. It is my guess that the interior plastic panels won't weigh ****, and that removing them for minimal weight loss at the cost of perhaps looking less like a street car isn't the best isdea. I got my whole inside painted base/clear so I could ride without ANY interior, but if it proves to be too loud then I'll know how much more weight I'll be adding by putting the panesl back in.

The only thing I can't weigh is the heater core and blower motor, because they are already back in the car - and besides, unless youre REALLY hard core I don't think you'll be removing your heat and only sourse of ventilation in the car.

Here's another awesome thing:

I've got all the suspension from a 1994 Integra GS-R, including the rear disc setup. We will finally see which weighs more and by how much - drums or discs!

If anyone already has all of this info, then please let me know because I'm curious to see if my findings will be on with findings of others.

Here's a question for you guys now:

Has anyone ever seen real data on how much a D-Series motor/tranny weighs compared to a B-series tranny? Not guesses, but where somebody weighed them both?

The reason I ask is because my 1992 Si was rated at the 2326lbs., but the last time I weighed it at the dragstrip it was "only" 2289lbs. This was with a Type R swap, bigger front spindles from a GS-R, strut bars, full interior etc. So this leads me to believe that the B-Series doesn't add much weight, and if it does than it is very easily made up for by various things that we do to our cars and might not even realize it.

The only thing I did to make it lighter was take out the spare. Other things that we do to lighten them up that we may not realize are the following:

Wheels/tires. If you own a set of lightweight wheels then you reduce that stock weight because stock wheels are steel (unless you got a VX:hammer and wheels like SPOON, Rota, Racing , Mugen, etc. that weigh 8.5-14lbs. will drop your vehicle weight considerably because you multiply it by 4.

Exhaust. Stock exhausts are heavy as hell. If you have a regular cat-back stainless stell exhaust with mandrel bends from a company like DC, Tanabe, Greddy, 5Zigen, etc. then your exhaust is much lighter than stock. Some exhausts like the new Tanabe Racing Super and Hyper Medallion are even lighter than before.

That's about it really. Of course we can all do other things like take out A/C, switch to non P/S racks if we have Si/EX/LX/DX auto, but since the cars didn't even come with this junk all we're doing is getting back to base weight, or trying to.

I'm sorry if my post is too long, but I fell that weight is a big factor when trying to go fast. Those with lighter cars will spend LESS money to go as fast or faster than the next guy with a heavier car.

And one more thing:

Think about the big weight difference between the Si and the CX/VX. For you comfort buffs, you could have A/C, add P/S, all the little trinkets like power mirrors, etc. to the CX/VX and STILL weigh less than the Si. The main comfort feature on the Si that adds weight is that damned moonroof. I think Honda added bracing in the chassis on the Si because of the big-*** hole in the roof. The hole decreases rigidity, and adds a little less safety in the event of a roll-over, so why would they not try to brace it more.

That's why the Del Sol is so damn heavy even though it's smaller - very dense because it's braced so extensively.

Oh well, anybody with info on the weights of anything that can be added/removed to our 1992-1995 hatches please post it on this thread.

Later y0!

owen_the_soyboy

GREAT INFO

I too have removed the rear seatbelts, HEAVY stuff! and I can weigh them Monday at work --->because my job has a certified scale for weighing parts under 40 lbs.
I still need to remove the fronts also, I will weigh them as well...
NICE! Because I'm going with 5 point belts instead.

Interesting differences/similarities between models...
Are there bigger brakes on any of those cars?
different header designs?
different catalytic converters or mufflers or resonators?

man, I love honda-tech

B18C5-EH2

You just brought up an interesting thing:

The CX/VX has the catalytic converter in the exhaust manifold, while the DX/Si has a totally separate catalytic converter and exhaust manifold. Design is totally different. Whether the CX/VX design is lighter, I don't know for sure.

Brakes? We know the Si is the only one with rear discs, but as far as FRONT brakes goes, let me look. I think they're all the same because they all use the same brake pads, but I'll double check.

Typo before on Si having drums You know what I meant, right?

One more thing:

Does anyone know of a totally RELIABLE website that offers all the specs on the various cars? I treid Edmunds.com, but they suck. They were right on a few weights, but wrong on a lot too

I am curious to see what difference there is in weight from the 1994-1995 model from the 1992-1993. Honda added some features as std. equipment in 1994 I believe, plus the extra airbag and stuff too.

Anyone? I'm looking for a good site right now...

lucas569

if you go to hybrid.org under members rides (i think) jerome soh has a breakdown of the parts weights. i'll try to find it....

lucas569

heres http://hybrid.honda-perf.org/thelist.html the list! who loves you baby!

Rodney

ok, sounds about right. my car ( a 94 si) weighed 2260 will all the options aside from a/c. now it weighs 2398 with the swap,5 lug, rollbar, huge rear sway bar etc. oh, i did pull the srs and abs.

Evil_Wizard

Hey B18c5-eh2 go correct yourself the Si is the only one that comes with rear disc not rear drum.
