s13 hatch on a diet

[whereda40at]

i want to make my car lighter. so far i have only taken out all the interior in the back and removed all the sound deadning and s14 seat belts. im ready to take it a step further. i need to know what is safe to cut out so that i dont loost the sturdyness of the body and frame. pics will be a big help. i have a cutting wheel waiting to be used.

[nrmskate]

Uh, I wouldn't be cutting anything out.... Structual wise.

I would get rid of A/C unit first.

[whereda40at]

a/c is also already gone. i have removed alot of things. im thinking that the next this are carbon fiber/fiberglass pieces. but i want to remove things rather than replace. the car is not driven daily. its my weekend warrior.

[I LUV MY S13]

removed the heater core and all that?

[5t341tH]

replace ur glass with lexan?

[zugoi]

lose weight yourself?

[nissandr1ft]

I can't think of much to cut out other than the rear speaker brackets. If you havent already pull the rear seatbelts, rear speakers, automatic seat belt computer, etc...

[Flicktitty]

if i were to build a hatch, i would look into a lexan rear hatch window with a carbon fiber hatch, i couldn't imagine the weight savings in that.

other then that, heat,sound deading,radio,glove box, lightweight bucket seat, loose the p/s.

etc.

lol..................

[240sxjohny]

ok to begin remove you rear seats and replace your seat and passenger seat with light weight seats if your going solo take out the passenger seat aswell. Take your door cover off and take out all the mechanical stuff including motor.. if you have one fot the windows. Take out your center console aswell as the whole entire carpet. You should also take out the glove compartment infront of the passenger side. Since you took out your a/c you should also take out the ac vents since you no longer need them. it should look like this...:bigok:

frp doors that chaser aero has a sale on right now!

yeah def rear seats gotta go, noone can sit in them anyways.

[drifter_for_life06]

smaller battery, carbon or fiberglass parts(you can get pretty much every single body panel for our cars in CF) lighter wheels, flywheel and exhaust(titanium).

[epics13]

all good stuff to take out but dont forget that spear tire in the back. lol, since ur not dailyin it u shouldnt worry bout getting interior panels in carbor fiber just get rid of it period. also i seen someone cut out the whole where the spear tire sits and cover it back over with sheet metal. hope this helps.

[whereda40at]

i have done most except for what a couple have said. i still have the heater which i can remove. i cant get rid of my glove box because i had a few things in there. most of the carpet is gone. i have weld raceing wheels. cant get much lighter than that. exhaust is just a stright pipe flywheel is aluminum. speakers and auto seat belts are all gone also. washer fluid res is gone.

cant go lexan. if i do then i cant drag race in a street class. i have to also have my door panels in and a passenger seat. lighter seats are a need.

so i can remove my heater, vents and duct work, carpet in the front.

replace all body parts with c/f or f/g. but that stuff cost money and that is something that not many of us have right now. haha

[CamryOnBronze]

I have a cf hatch with OEM glass installed and it was about 15 lbs lighter than the stock hatch and glass. With lexan I'm sure you could save another huge chink of weight. But, I see that you don't want lexan and you don't want to spend money, so that info might not help you too much. :lol:

[ranger240]

heres a thought.. get onea those oem dash caps (the type used to cover cracked up dashes) and use that in place of the oem dash.. you might have to make some frame and it might look mad ghet but im sure it'll save you what like 20-30 lbs?

if you put time into it, you could make this look really cool

[LongGrain]

drill out those silly rear seat brackets that wrap around the shock towers.

looks hella nicer without them anyway..

if you don't want to go that route, you could also strip all the padding and crap off your existing dash.

i have 420whp and all of my drivetrain is done. motor is built. i just have to do the head and go from a gt2876r (still a bottom mount turbo) to a borg warner 366xxl.

the best i went was a [email protected] but i now have a 2 step and looking to get micky thompsons too.

[projectRDM]

It's not like you're the first person to do this. Stripping a car of excess weight has been talked about on here since before I was a member, and everywhere else too for decades. Superficial metal is easy to remove and if you know how the chassis is built, it's pretty easy to know what you can remove.

Search. There's no way you won't find a million thread all over the internet.

i searched and all i got was most stuff that i have already done. i was wondering if there was more to be done than what i had found.

i dont know how the chassis is built so its not "pretty easy". thats what the ?'s are for.

[EroGori]

I don't think there is that much weight to lose in the dash, it isn't all that heavy. Do you still have power steering? You could always gut your steering rack to run a manual setup.

What does your wheel/tire combo weigh? Aluminum driveshaft maybe?

[monsta_civic]

Race naked!!!!!

[T_wei]

damn son.... what you gonna be doing with the car stripped like that? if your not tracking or drifting i say don't do it. u'll regret it later

[RacerX1]

He already said its for drag racing..

[moses]

you can take out your front bumper support. i did it because of the sr and its a daily driver. you could probably take out your rear on too.

[ranger240]

removing the front bumper core is STUPID for a daily.. none of the oo-la-la airflow for an oversized intercooler is going to change the fact that it isnt a good idea... checkout some pics of crashed cars w/o bumper core supports.. it aint pretty, in fact its pretty stupid.

imagine say, you hit a tree.. if you have no support, your wimpy aluminum intercooler, radiator/core support and then finally your engine/crossmember combo is whats going to finally grind your car to a brutal halt. that crap is less metal to offer deceleration and slow your car.

crash, get injured but yeah man your car HAD an extra 5 hp

w a bumper core the force is distributed between both frame rails, allowing the car to slow the way it was DESIGNED to do.
that oh its just a 5mph bumper b.s. argument ripped from the pages of SCC is crap too, a metal bumper is better than nothing.

do not take off your core for weightsavings.

[projectRDM]

I disagree slightly.

For a drag race only car, one that is not street driven, removing the bumper reinforcements isn't as much an issue. Here's why:

1) The front reinforcement is designed to withstand head on impacts, on a dragstrip there is zero chance of hitting anything head on. *If* you blow out a tire or loose control you're going to hit the wall at an angle, and offset side impacts do substantial damage as the sides of the reinforcement don't support that type of collision. The energy absorption is directly head on only. In that case, the reinforcement has done nothing to ease the damage or impact.

2) At drag race speeds, the reinforcement will do very little anyway. 100MPH impacts are more than enough to shear the bolts off and push the reinforcement well into the engine bay, whether it's there or not the car is still totaled and the driver is seriously injured.

I don't condone removing it, but doing so doesn't increase any risk factors exponentially.

For the rear reinforcement, the S13's back section of framerails is heavily reinforced to withstand fuel tank damage, again it's unlikely on a dragstrip the rear of the car will see a direct straight on impact, if ever.

But if the car is ever street driven, yes, keep them both, if not for yourself at least for the safety of others on the road.

[landins13]

im 5 10 and 150 lbs. how much more you want me to loose? :tweak:


get down to 135

[DALAZ_68]

what about the qtr glass, cant u change it out for plastic, front and rear windshiel aswell...?door glass...thats some good qeight right there...power steering turned to non p/s rack


breaking out the FSM and removing what u dont need wiring wise...i mean shit, i took out an s14 ABS complete cabin/engine bay loom and weight roughly 40 something pounds +...

dont know if u have or can remove the wind shield wiper assemblies /motor...

great points

[QuickSpoolSR]

take out your cutting wheel, and cut off the front and rear toe hooks, those things are really heavy

[QuickSpoolSR]

i would asume you also got rid of the antenna and motor, and the rear wiper and motor, does it have a sunroof? that would be the first thing i would not want to have in a light weight car

[skate_osiris_4life]

:wan:have you replaced the glass windows with a lighter material such as plexi glass. im sure that would save a ton of weight. and maybe if you havent yet get a fiberglass hood....does urs have the sun roof also? :eek3d:

[ixfxi]

its so fucking hard for people to read... repeating the same fucking suggestions over and over


its like "hey dude, the windows.. put PLASTIC ones..."

"cut off the tow hooks dude" wow.. 2 lbs 1 oz!

fuckin shit.. father russ had the lightest S14 known to man, he said it best.. fucking search through your own car and figure out what to take out. this is like a thread full of brainstorming FAIL


i am no fucking mathametician, but i can easily tell you that removing unecessary items will reduce your weight. if you toss your interior, and anything that is not needed, your car will weigh less. hmm.. those triangle supports on the rear shock towers? YOU GUESSED IT............

seriously, just use your head AND your imagination, surely you cant be this inept.

[ixfxi]

......and dont forget to replace your glass windows with plastic ones.

[QuickSpoolSR]

wow ur a dick

[Ali 556]

OP,

All what the guys said PLUS :

1- Redo the engine - engine bay - interior harness...for the interior harness you can try your best or get the PAINLESS harness it come with 6x fuses and switchs and everything.

That's ~ 40 -45lbs gone.

2- For any S13...Do a Silvia Conversion Some dude measured his S13 On FA and the Silvia Conv Saved him ANOTHER 40 Lbs.

3- Do custom Tube front rad support And Get a Civic Mini rad And 2x 12'' fans (1 push and 1 pull) And Shorter IC piping (what the dr''a''ft fan boys call ''mid'' mounted intercooler)

That's another 15-20 lbs lost

4- Get a racing seat not ''oh look @ my bride seat'' NO get a real man's seat

Kirkey Racing Sell some nice stuff :

Kirkey Racing Economy Aluminum Drag Seat - RacingPlus.com (http://www.racingplus.com/racing-seats/kirkey-racing/economy-aluminum-drag-seat/1451p11532)

5- depend on the class you are running...throw away the stock fuel tank and get a fuel cell. i don't how much power you are making...but a fuel cell + 1 Bosch fuel pump is more than what you want and you will save some lbs too

need more info...?

PM me

[drift-s13]

DUDE! cut the back of that shit out and make it a drift truck!!!!!!!!!!!! haha theres one down here and that things bad ass

[Ali 556]

Also Don't forget The front Rim+ Tire combo...you have welds right...get 17'' x 4'' or x 5'' that more than you want..alonge with skinny tire

And keep the stock brakes b/c they are small and lighter than the Z32 / whatever brakes, Get some Ceramic pads or Kevlar pads And Slotted rotors.
