Ok, so here is the problem... I've got a bone stock 1990 240sx with around 130,000 miles on it... No oil leaks from what i konw of and everything seems to run alright except when i take turns in second the back end makes a wierd ratteling noise... Its not the hatch, it sounds like it just doesnt have enought power and the back end jumps out... well it like skips... its just very odd to me, i had a RWD car befor ethis one and it never did that so i was just wondering if thats a problem or if its fairly normal... also, it is a 5-speed with the stock 2400 and i keep getting beat by a crx dx with a mid-air intake and a straight pipe from the downpipe all the way back to a top end exhaust tip... im really getting mad at this and i think this car should beat this crx... just wondering if that sounds odd to anyone else with the same car or something like it... and what could be a cheap/hp gain mod i could do right now... i dont have the money for the cold air because of no job.. haha but i do need a little more power/noise out of the car... i dont like driving around a stock ass ride... lol, well anything and everything helps... thanks... later on

it kinda sounds like wheel hop, or your driving around on a welded diff, but i havent experienced either of them. does it only happen in second? as for power mods, i have heard that bolt on mods (intake, header) dont do much, but cams are great. you could turbo your engine to make 200whp and keep costs and stuff pretty low. turbo 240 = vtec death

Yeah i was kinda thinkin maybe a welded diff. because ive heard a few people say that about there cars... i just picked her up about 3 weeks ago and im just starting to get into the nissan and 240sx world... Whats the best way to tell weather it would happen to be wheel hop or a welded diff. because say im at a red light turning right and i just stomp on the pedal and dump the clutch out and tr;y and take the turn it makes this god awful sound and seems like its gunna fall apart... its not brning out well it is but thats not the sound, to tell you the truth it sounds almost like turbulance when your on a plane... lol, but no it happens from 1st thru 3rd and sometimes it does it when im turning in 5th at low rpm's. But the mod thing is wierd because ive heard that a full cold air and a cat back or a straight pipe would do my car a world of diffrance... cams are deffinatly in mind and im looking into an undercar pully kit but from what im hearing that HP gain is mind over matter... just replacing the old part with a new one... and turbo'n is out of the question right now man... thats a whole lot of money and i would have to get the intercooler, the turbo and the exhaust manifold, then not to mention all the pipeing but its a for sure for later on when i get a job... im gunna buy it peice by peice and just build it up, thinking of posibly purcasing a new engine for it and building onto that, just turboing the one i have now untill it blows and then doing the swap or just waiting untill i get my 2nd engine all done and then keeping the other one just as like a lay around motor... What all do you, wel should you do to the internals of the 2400 before you turbo it??? ive heard from some people thatthey did nothing but it seems to run kinda shitty... and id rather be safe than sorry right now...

you should kill that crx.
my old stock 240 could beat every honda that didnt have DOHC vtec, and could keep up with some that did.
do you have hicas? i dont think that would be the problem but im not 100% sure...
id say look into having someone who knows what their doing tear into your diff.

i dont think its welded, but id say thats your problem as far as cornering.
either that or an axle...but youd be able to see that.
the power issue is something else though. buy a service manual and learn how to check your computer for codes.

hicas???? not entairly sure what that is... and yeah, i was thnking i should smoke it too... i actually do... 1st gear i leave it which is wierd with it being the lightest honda and all and the 2nd i pull.. then 3rd he starts commin back and 4th he flys right past me... i cant belive im loosing to a honda around top end!!!! :banghead: :banghead: :banghead: :banghead: :banghead: I was thinkin that there is something wrong with it myself because its running good but performance wise it isn't the greatest... i ran a 5.0 and got entirely smoked on roll... but from the line i beat him????? im bangin my head aginst the wall with this project... ive gotten down into the engine a little bit but not as much as i want too yet seems as how i dont have the tools... And can having loose/wore out belts rob you of massive HP because my belts are all ate up... they dont look too great...

hicas is 4 wheel steering, some 240s have it, some dont. alot of people say its bad for drifting, and there are hicas lock kits out there that disable it.

do a tune up- spark plugs, " " wires, fuel filter. etc. etc..
Intake, exhaust, etc. etc..

i ran a 5.0 and got entirely smoked on roll...

240s don't have much power in the top end/high reving area, I'm sure you know that

but from the line i beat him????? im bangin my head aginst the wall with this project...

You took off better. 240s are good off the line

Im not sure if i have 4 wheel steering or not... I am brand new to the 240 scene... Iv'e been looking into the cars for a while but never reallt thought i would own one because they are very very very rare around herea nd you have to pay a pretty pennie for one... Is there a certain way to tell if you have 4 wheel steering or not besides just riding in it and noticing it... im pretty sure it doesnt but who knows i could be wrong and for the tune up thing i have had almost everything tuned up... plugs, wired, oil and filte change, radiator flush, new pads - roaters, new intake filter, valve cover gasket - Intake mani. cleaned out, stock intake blown out, (valve springs, rocker arms, and cam all greased up... The only thing i have left to do that could possibly be robbing me of so much power is the belts... They slipped my mind, that should have been the first thing i should have done... lmfao but somehow i forgot about them.. i love this car tho... im giving it as much love and respect as possible... I dont wanna be one of those guys who just gets the car because of the name... ive done my research thats why this CRX beating me is killing me inside and im getting beat by a like 90 or 92 grand am GT with a cold air intake... Thats hurts a little worse... lol, i guess all i have left to do is go boost... I really dont wanna rice this car out too too much... sorry for the book every time i post but i really need some help...

Maybe the crx has some other parts he/she's hiding lol

I got beat by my friends crx with mild internals, bolt ons and nitrous, who told be he only had cams, intake and muffler lol and I still got him a good distance off the line haha FR>FF

nah, i know this guy... he is in our racing group that meets up... and ive helped him put a few things together in his ride... anyways its not really no bigg deal... i just need some parts... lol, and btw what cams swap would you recommend for the s13?? thats really the first mod i wanna do to it after the intake and exhaust and short throw... is there like a really good swap you can do to the s13?? and should i just go ahead and swap the camshaft while replacing the cam wheel???

when i take turns in second the back end makes a wierd ratteling noise... i do need a little more power/noise out of the car... n



axle going out? what sound r u talking about? more info plz...

more power for cheap, get a bike

more SOUND out of ur car, get a civic

240 KA are slow, live with it....

why did u buy the car?

When im turning left or right i cannot go thru the turn in 2nd gear without wheel hoping... and thats exactly what its doing... like when im in first leaving a light and i hit second and go thru the turn it feels like the back end is just skipping along... that ONLY happens when i gas it but sometimes i have too, and i just dont wanna let the problem go... Thats basically whats going on... the noise really isnt a big deal its the wheel hop... and i will NEVER own a civic, too much money to make them fast... the nyou have to swap engines every week or every time you run at the track!... i LOVE ka s13's... they are the meanest (well can be) looking cars out there and they were my one true love... lol, i came about a deal of a lifetime and took it and ended up with my 90 kae... Bikes are fun but i love this car and i dont wanna get cheap upgrades... everyone knows you get what you pay for in the car world... i just dont think this car is running exactly how it should... Alot or experianced s13 guys are telling me i should have beat that 88 crx dx with wide body kit, CF hood, momo knob, sparco seats, sparo pedals, straight pipe to a fart can and a warm(mid) air intake(lol).... sorry so detailed but i wanted youguys to know EXACTLY what it has...

haha well if you have hicas there will be a light to the right of your steering wheel beside your rear window wiper and blinker button. or can look under rear of car and if you see tie rods connected to tires and a litle hydro pump. you have hicas. i doubt thats your prob tho. i have hicas on mine and for about 2 months it didnt work right and had no wheel hop. sometimes feels like my ass slides when i shift but i doubt thats hicas prob. also i dont see anything wrong with civics. and i would say stock for stock the crx will win. i owned a crx with a 1.6dohc non vtec that could run mid 12's with a small nitrous shot. and i put intake and custom echaust on 240 and still slow. i would just have someone look into your diff. i dunno if 240's have this prob. but i had a fwd car that had a bad axle when he turned it would have a nasty sound and the axle would vibrate. maybe thats happining to the rear end of this car?

bwhahhahaah he says nitrous.....thats force induction bro.......of course it will win. And how small a shot we talking? I have a hard time beleiving this one. No wheel spin???

dude a stock ka is slow as shit. Live with it. Dont waste money on an actual intake, because you still wont win shit. I had a 240 with header, bigger exhaust piping, high flow cat. All i noticed was mid range power and it was whole hell lot louder. But it wasnt fast by any means. The only way to do a 240 is turbo.......so start saving and piecing. Like someone stated above bolt on NA ka mods wont do dick.

ka-t.org , there is a turbo thread for dummies. Telling you what you need for certain hp levels. 200 whp is pretty cheaply done and can be done on stock internals. THat 200 dollar intake would buy some parts....so would the header and pulley......dont buy any of that crap. Sure it may make it run "better", but for the money you'll be pissed off. Just save man, just save. Its better for the long run and alot more power out of it. Then once you have the basic stuff.....its minor upgrades that will make a world of difference. Look into JGS stuff. They are links on www.ka-t.org that you should snoop around on.

ahmen

LSD problm...

small shot = about 50-100 range. and some call nitrous forced induction some call it an additive. either way it makes you faster. and i never said there was no wheel spin. why you think i sold it? it would spin till 3rd on street tires. =( but thats off topic.

Civic's are ok i just dont like them very well... there are a WHOLE lot more cars out there with a WHOLE LOT mor power... why the slowest one? lol, thats just my view tho and ive heard so many things about the rear end... lol, i really hate to say this but i think i have to take it to a shop :(, ive had gear heads, ricers, retired mechanics (lol) and a few other people look and feel it and they cannot tell me what it is to save there life... about 50 things come to there mind... looks like im just replacing the entire rear end unless i decide to really take it to a shop... Im really suprized that no one has had this problem before tho... and im now learning that ka's are actually really slow... lol, i still love the car tho... and what do you guys think of E-turbo's?? if youall have heard of them which im pretty sure you have... i personally wuld rather have ballbearing original but a kid near me has a type R integra with twin E-turbo's and it cut 2 seconds off his time... suprized the hell outa me... but yeah, the rear end is a mystery still...

I apreciate all the help tho guys, i think im just gunna have to google it up and stqart doing my research a little earlie... this deal just came up on me kinda fast... i really didnt want this car untill i had the time and money to love it with but it's like an accidental baby... just came outa nowere but you still gotta give it as much love and care as if it were planned... lol! thanks tho, you guys helped out quite a bit
