s15 helical vs nismo 1.5/2way

[gnomes321]

The only draw back of the helical that made me decide to get a 1.5 kaaz over it was how it would act like an open if a wheel lifts. I can't stand almost getting stuck in steep driveways and dips and VLSD's weren't even an option because for the most part they suck.

I"ve had my helical for 2 or 3 months now...I've three-wheeled maybe once. Otherwise, it does great. Very happy with the performance at the rainy auto-x this weekend.

Um, this thread needs to seriously get some facts straight about s15 helical diffs. Especially before naed240sx comes in here with flying fists, lol.

Just to bust a few of your posts already:

1) an s15 fits into a stock r200 punkin and can use the s13 half shafts. I know because that is exactly what I am using now.

2) Obx helical differentials have a horrible reputation, just go on Ebay and get an origginal s15 helical shipped from a Japan yard for 400 to 550 on average. Spend an extra few bucks for soemthing SOLID. Obx makes its products in China...eh, some of their products have mixed reviews.

3)A helical differential will bias most of the power being planted to the outside wheel on throttle

4)Which feels batter and what is more useful is dependant on the driver's preferance. Not everyone uses their car the same way.

5) Helicals can be great for autox, drag, and road racing. Look up on how these babies work before condemning them. I love mine to death.

6) You can keep the same bolts to attach the helical differential to the r200 ring gear. The bolts of hubcentric.

....I'm pretty sleepy, so just SEARCH guys! Come on now....

EDIT*BTW, I may have a spare set of s15 output shafts in my closet. I clean it out tomorrow and know for sure. I'm 99% positive I have them.

I have a kaaz 2 way. Its not loud. The inside wheel hops on slow, sharp turns, but theres no clunking, only a little grinding noise here and there. Nothing loud at all.

From what i have read..

an HLSD is not a true LSD. In the sense that ..it is active all the time time because it is gear based and the fact that it actually allows torque bias between the wheels.

An HLSD will allow somewhere up to an 80/20 torque split depending on conditions. Its great for grip driving in this aspect as you get the locking potential of the diff on exit acceleration , but not so much in the corners that you can power oversteer as easily as say..a clutch type Nismo diff

I'll give you 5 bucks through Paypal if you can back that up, lol

[keith0486]

id say go with the nismo 1.5 cus i have that in my s13 and i love it. its nice and quite to no noise what so ever so thats my 2 cents

Um...the only thing i can do is post my resources. Ill be happy to =D

I read about it awhile back and its all i was going on.

[boznuttz]

It's cool that you searched and props for it, but don't believe everything you hear from Wikipedia, lol. I know a lot of people that submit info for it and....they're crazy!!!!!!

[Chukidori]

it seems well written ..

and supports whats beens said here. But i think it was my bad for interpreting some things wrong.

I personnaly want one ^_^ i want a time attack car, not a drift car, and the helical sounds perfecto.\

[boznuttz]

High five to you! I love mine, and you can find some good deals on Ebay too.

[Chukidori]

What do you know about the OBX helical?

Does it fit into the stock s13 diff housing?

never mind o.O just saw the s14 thread

nismo clutch type FTW...... as long as you dont mind a lil clunking...

[yokota180sx]

get it installed correctly and it wont be clucking

if your actually comparing the two....or asking which to get, yoru an idiot

[FusionR300zx]

i was just tryin to see if it was worth the extra $120 for the nismo 1.5/2 way when there was a group buy. but everyone says they're loud and obnoxious so i was just trying to get other ppl's opinions about the HLSD.

and don't say there's a writeup about it cuz i had this like posted before some1 did that write up about it which convinced me to get it more.

why do u even post on here?

[bone_stock_240]

They both serve different purposes, which of course you would know if you researched it. Just get the helical. If you do get stuck with one rear wheel in the air, just pull the handbrake a bit. Since that will cause a torque to be applied on the wheel that is in the air, it will send more torque to the other wheel, depending on what the bias is. Problem solved.

VLSDs suck in the wake of helical diffs. May I sugguest an OBX depending on your power output? They seem to hold up well if you inspect them properly.

With an s15 diff you have to buy s15 output shfats as well. With an OBX you can use your stock OPEN DIFF output shafts.

s15 helical with new output shafts $650 shipped

i post on here becuase im like the only person that has had all this **** on multiple cars

the Nismo 2 way didnt clunk in my 180 evarbut i also had it installed correctly.

a clutch type LSD is way worth the money

Don't even pay him any attention. He's an *** for the most part. Asking a question shouldn't be cause for a flame, granted if its hey will this s15 front fit on my s13 then sure, because he didn't know. It's a good question for people who don't know a lot about differentials.

yokota180sx don't take any offense, but you do come off like an *** most of the time. When its called for its all good, but dude common every post you make is either flaming some one or trying to rip them apart b/c their car isn't track worthy.

Im with Morph Yokota Alot of your posts have good information just take it easy on people sometimes hahaha

It's supposed to "cluck" (Mechanical types) in a turn. Installing them is not hard, and follow the break-in instructions before tearing a$$. If it's growling with normal driving, then the gear oil is more than likely the culprit (too little or old). As far as saying someone is an idiot because they asked a question, you need to know the subject matter before posting. Oh! Enjoy whatever limited time you have remaining in Yokota. That scene there is just a momentary illusion for you, and definitely the cars are too. Enjoy it while you can before you return to the USA.

Back to the subject matter...

The S15 helical- I use it, and it is good for daily driving, drag and ciruit. It's no punk with drift, either. If you want a diff that locks up with hardly any torque, mechanical is the way to go.

The guy who posted that when he ends up in a three wheel position, why would you want that wheel in the air to spin? You want that traction transferred to the wheel making contact with the ground. That's the beauty of a helical and VLSD.

VLSD, helical, 1.5 way and 2.0 way mechanicals- all better than an open diff.

So what would be a step above the HLSD for grip only (i dont give a damn about drifting)
