Wasn't it the most searched/viewed article in regards to chassis foaming on the entire interweb? lol

You's a famous person haha

[turbo_dreams]

Gots me a tig welder if you wanna do some stich welding drew.

^ nice good investment deffinatly have to play around with that.

the foam seems to yeild the greatest gains
Chassis stiffening foam result - Part 1, qualitative result*56k no go*: 240SX Technical Forum: Nissan Forums / Infiniti Forums - NICOclub

i think im going to try it. seems like what i need to fix my problems

If I could urge you not to, you would save a car.

Pourous or not, once moisture goes either under the paint or rusts away a layer of metal "before" the foam, it just eats right past the foam on all sides. Heavily rusted metal breaks away in layers.

Remember your in NY, heating and expanding from winter days WILL displace the foam and cause you a rusty hellish nightmare.

tx/ca is a different story though

[singlecamslam]

Yeah i agree with the dude above. I wouldnt use it, and stitch welding? If you got the time and patience than go for it. Best you can do is replace the stock bushings and get quality rucas and stuff. That should help a bit.

[Tenchuu]

i recently put in a C pillar brace in my S14, that really gives it a solid feel that it was lacking.

[slider2828]

Miracle X Bar... look it up.... works wonders for rear. do not get copies cause they suck

[Sti_Guy]

get a roll cage, walah stiff enough chasis.front/rear strut barsTHICK(fuck name brand, as long as they are BEEFY, it doesnt matter) suspension parts (tie rods etc.)poly bushings, megan coilovers are good.... Look at all the formula D drivers who use them. Just because it isnt name brand doesnt mean it Cant work just as good.

[brunswick240]

floor board strut bar?

so what can i do to possibly stiffen back up the car? i was going to start with checking over all the bolts that attach the front/rear subframe to the car. i have nismo mounts and spl collors. i was going to get spl diff bushings because when i let off the cluth the rear chatters, also if i shift hard form first to second ill get wheel hop then the tires just spin.

i was also thinking of a power brace for the front and possibly fender braces i heard that it does wonders..

any suggestions will help. i do not want to cage the car. so that is not an option.

thanks

Your car feels loose and sloppy because your bushings are all worn out. Replace your bushings with poly or spherical ones and then go from there. I'd recommend poly as you seem like one of those "daily driveability" types who would kill themselves if they had to sit in a bucket seat for more than 5 hours.

It's not the foam that holds moisture. It's the fact that the moisture can't escape because it's trapped by the foam so it eats away at the metal that's not protected cause that spot originally came from the factory as a place that wouldn't be exposed to moisture.

OP, if you foam your car you might as well call your insurance company the next day and have them total the car for you.

500 frickin dollars for bling bling jdm part. What the hell... its great, it works, but damn the price. It should be like 200 bux max.

[Koopa Troopa]

I don't see how it'd be possible to make a miracle cross bar for the S14 as the strut tower bars and the c pillars have a nice layer of sheet metal between them.

[turbo2nr]

i dont mind a stiff car, trust me im not the type to bi*ch if its too stiff..

anywho.. the foam is something i want to do but now this mositure issue worries me, what if i tried to spray inside the pillars first to add a layer between the foam and pillars?

this sucks i just orderd the foam spent $100 bux on this...

[SoSideways]

The pillars should be fine, as I don't see why there would be moisture in your pillars.

Now rocker panels, yeah, I can see where the moisture would come from.

But to be honest, if you plug the holes after you foam your rocker panels, there shouldn't be water/moisture in there anyway.

Then why would you completely dismiss the idea of a rollcage? If you want stiff it's the only way to go.

Nissans are prone to rusting as it is. Sell that foam.

[Brian]

God, my new car should be pretty stiff.

I wish I had a Miracle Cross Bar though.

Safety21 7 point
GT Spec tower bars, C pillar bar, trunk bar.
NAMS gacchirri bars

Probably going to add a couple other bars to the cage.

Shit yea

[slider2828]

Yah I would cage the bish.... but still I would get raped in norcal for that by cops. Yes you can make miracle X bars.... But think about it, welding it with QUALITY metal not trash metal is very expensive.... If it flexes, its useless.....

[turbo2nr]

i cannot cage the car as of right now, as for funds is the main issue, when i do a cage i want it done right not a blot on cage, i got estimates of 1200+ for a good cage, so thats not in my buget right now..

as for getting a new car, i cant like i said funds are not their i wish i could afford a 350z but it would be slower then my s14 and not handle as well, not look as good.. blah blah blah

i'm taking my chances with the foam, my car doesn't see moisture i park it in my garage and take other transportation when its nasty outside..

i am looking into fender braces and what not. to help with the chassis stiffing, its so many choices its hard to decide what to get first. im going with power brace and fender brace, then rear arms and diff inserts. along with the poly foam it should help..

[murda-c]

You guys, 240sx are made with DURASTEEL.

we don't need no stinkin cages.

[Brian]

cages are the shit.

You can hold onto them.
Put stickers on them.
Look at them through the window.
etc.

[slider2828]

Not handle as well 350z? Are you smoking crack? Not as fast? Another hit on the crack pipe? Come on now.... 240s are not that good in handling when it comes to newer cars..

[turbo2nr]

im faster then a 350z i have several 350z that will account for this. stock for stock, no 240sx will not out handle a 350z, a modified 240sx will imo.

[slider2828]

Dude are you freaking talking about drag racing or on the track.... Overall performance of a 350z > 240 that requires turning. lol

[xs240]

My 240 is faster than a 350z, m3, stock evo and many other cars hehehe Stock 240sx suck though. Fun beginner car but suck when you wana drive hard... track, daily, etc... You guys underestimate our cars... I guess there's a reason. Most people use 'drift' and 'jdm' parts to look baller rather than do their research to make the car stop, corner, grip, acelerate tractiveley better. It's not very hard, just people have made up ideas in their mind about our cars (being drift cars only for example).

For example look at how you guys said get polyurethane bushings, yet it's not actually a good idea to improve the car's overall flaws.

Also our cars are not as easy to drive as some cars out there, however that does NOT make them slower, just means you as a driver are slower. That is all.

I'll post track videos in the summer... then again there's plenty out there if you youtube/google for them.

Racepar1 on here can probably own most zilvian cars on track, yet all he has is a KA24DE. So could nikeyboy555... keeping up with turbo 911s, including a GT3 (still get owned in straight line but still catch up in corners thats impressive). He too has a stock KA24DE with boltons.

Check on youtube. This should all tell you something.

[bejota180sx]

and how do you know those gt3 are being driven right?
not saying those guys don't cause at least racepar1 i know does but... how do we know those gt3 and 911s and blah blah blah so on and on are being driven? it's not only the car it's the driver included...

again not telling them they can't do it, just take that factor into consideration

This is the truth

[slider2828]

OMG people are just crazy... you guys are comparing to mostly stock 350z's... You are like comparing apples and oranges.... modified 350z vs. your modified bla.... come on please.... twin turbo 350s with a bunch of suspension your telling me you guys on the track can take it out? Please.....

Yes we are...

[blownmotor]

The S-Chassis was made until 2002. Our cars can still hold it's own against many others even till today. Doesn't that already mean something? Nissan kept that same suspension design for so long means they're either too lazy to change or they have something that was very well proven. Being that our cars are old doesn't mean it can't be competetie still. I think our cars are very easy to drive compared to others that rely mostly on traction control and yaw sensors and etc. We don't really have those luxuries. Probably ABS at best. Look at most modern sports cars on the market today. Lightest one would be what the MRS or S2000? Come on S2000 weigh about as mush if not more than our cars.

Get back to the subject, stitch welding the seams is good but puts a hard ride quality. Question is how far do YOU want to go as to making it stiffer. Chassis development take a long time and a lot of knowledge. If you get a chance, look up the OPERA S2000 build. It ran Tsukuba under a minute with a mostly stock engine.

1) Nothing wrong with a bolt in cage if installed correctly. Save your money.
2) Congratulations, you've just contributed to the murder of what was a clean looking S14. Unless you vacuum seal it and never remove it then it will see moisture.

You've just lost all credibility.

How would there not be any improvements to the car's overall handling and feel by replacing 13 year old worn out bushings with poly or fuck, new OEM bushings?

S chassis cars are known in Japan to be sucker cars cause they really don't require any talent to drive. Turbo and RWD with MacPhereson strut front and multi link rear. How does a car like that take talent to be fast in?

I've run down Skyline GTSTs in my 550 Alto Works and I've run down Type R RA WRX Imprezas in my Civic. Doesn't mean anything. Dudes prolly let off.
