Don't be so disappointed in it; The IRS sucks too. I've owned them both. If I had an SRA car again, I wouldn't change it.

The main reason why I wanted the IRS was a Posi. So I'd swap for a different manufacture's axle if I had to do it all again. I'd do the cut and weld camber thing with that axle. My 200 doesn't see many miles.

i just want good fitment. this is hard lol. i suck at fitment

plus IRS diffs are stronger

IRS gains at least 8 degrees fully compressed, it sucks. You don't want.

Although you are 100% correct. You can't really have funcitoning rear camber on a drift car.

David BOct 12, 2009, 2:29 am · #10

yea you can

why not? please, im waiting for another wonderful explanation.

attn jeffwins:

would you mount the solid axle in your z with duct tape? or zipties and pink spraypaint?

IggyEGuanaOct 12, 2009, 4:35 am · #13

why u complaining?  ae86 is sra.  learn from them.  dont need camber for fitment adjust the fender.  Those wheels are ugly anyways sorry, no i'm not lol

JayOct 12, 2009, 4:42 am · #14

Do the research. I don't need to put down an explanation, it's not the point of this thread

brewster240Oct 12, 2009, 5:27 am · #15

if you say something like that, be willing to back it up.

im not doing research. i do alignments, and i go drifting.

David BOct 12, 2009, 5:36 am · #16

it was more of a joke, i was just posting   to show off the free wheelsi spent alot of time sanding.

but in a way it sucks.... why so serious

JayOct 12, 2009, 6:31 am · #17

ugggg... You never know over the internet. And we especially never know with you.

WHHYY SOOO SEEERIOUS!?!?!? By far the most menacing voice I've ever heard come from any actor.

And brewster. Long story short. Anything after 3 degress is pointless for drifting. More tire wear, tramlining, Less footprint which results in significantly less stability and grip. A drift car is, under ideal conditions, to be set up for grip racing, which depending on the suspension geometry for the bound and rebound, and the angles of said, is generally and optimally set up at .5 degrees negative per 25mm of suspension travel to create the full contact patch vs. body roll. This is not taking into consideration of tire compound, height, width, sidewall strength, tow in, caster, spring rate vs shock valving, and more.

I could go MUCH more in depth. But I always get contradicted by people. I don't throw out information I don't know for a fact. Most of the time anyways...

If you have a car that moves 6 inches in suspension travel. Then maybe 3 degrees is good for you. But seeing as david is always up for more lowar, It will be impossible for him to have a really healthy suspension setup with IRS for drifting. Other cars get away with it, but the IRS on the S12 is just plain.... sucky

David BOct 12, 2009, 7:12 am · #18

i want 7 inches...

mod_mastazOct 12, 2009, 8:08 am · #19

Quit your bitching david. Get a 5mm spacer for it and stretch the tires. Done. Rolling the fender is no biggie either.

David BOct 12, 2009, 8:20 am · #20

im not bitching, i was just saying it would be nice to have irs
streching tires is hard when i use junk ones haha, im going to find a good set though

the same way these people did.

chevy V8 with a soild rear axle setup, anything is possible with time and money. http://www.youtube.com/watch?v=qZfIc4mMKxY

Ok chill guys. I really don't understand Jeff sometimes either, but it's his choice, his car. Some people learn by research, others just plow into things. I tend to fall somewhere in the middle, to be honest.

Fair enough.  I do, however want to hear reasons for putting an H190 into a Z31...so, Carlos...my ears are open.

ArroOct 12, 2009, 9:15 pm · #25

Actually the H190 is pretty stout. At least as much as the R200. And there are some LSD options for it, from what I understand the H190 was in other cars... I think Subarus?

I could have sworn I read somewhere that it starts to have issues around 250 ft/lbs of torque.

Perhaps I'm confusing it with something else...

Oh, wait...here it is from the Solid Axle Thread:

julieModel: H190
Differential Size: 7.49 inches
Maximum Torque Capacity ~285 lb. ft.


Donno how accurate it is, but if it is...then to me H190 in a drag car is quite the Fail.

Arro from what I understand the H190 was in other cars... I think Subarus?


Really?  I'll have to look into that...could reveal more LSD options.
ArroOct 12, 2009, 10:01 pm · #27

I wonder if I'm confusing it with the R160 in the Subarus. But someone told me once long ago that there were Quaiffe diffs for it....

Quaife (TorSen) H190 LSD was made for the factory 240RS rally cars.

There's also a rumor that some earlier Mazda and Toyota diffs were H190. I'll see if I can confirm this.

Some more info...

HF35 - H190 axle found in weenie 2wd Hardbodies.
HF37 - H190 axle found in weenie 2wd Frontiers

H190 - 190mm ring gear

This is taken from http://www.outerlimits4x4.com/viewtopic.php?p=1295215

The H190 has been used forever, pretty much on every Live Axle nissan made with the exceptions being the V-6 models and later 4x4 models. H190 looks like a mini 9" ford diff.
Models I've seen with the H190 include: (bolt patterns are 4x4.5, 5x5.5, 6x6)
'68-'72 datsun 510 wagon(leaf spring 4-lug) I believe these were 29spline, all other H190's are 31 spline gear ratio was 3.90
66-late 80's in civilian dress- Nissan cedric sedan(non US market)(coil spring 5-lug) Cedric wagons had the H190 leaf spring 5-lug H190 gear ratio 3.70
66-present- Nissan Cedric taxicabs/police cars (non US) (coil spring 5-lug)
S10, S11, most S12 200sx vehicles (only V-6 and turbo models had the R200, all other models didn't have IRS standard till the S13)FALSE, the IRS R180 was in all 4-cyl non-turbo from '85 to the end of the S12 in '88 (coil spring 4-lug) 3.90
Nissan pickup 521, 620 models 59-79 all models leaf spring 6-lug 3.90-4.30 depending on year and intended uses (some were camper specials)
Nissan 720 pickup 80-86 2wd regular cab/king cab all transmissions leaf spring 6-lug 3.42-3.90 depending on tranny and cab
Nissan stanza 83-84 4wd coil spring 4-lug probably 4.11
Nissan 1200 (datsun 210) wagon and ute (australia) leaf spring 29 spline 4-lug
these might have been as low as 4.66
There probably were plenty others....

A guy on here was making his own torsens for the H190...

Here they discuss a racecar with an H190 rear/axle from an '83 S110, it was welded:

http://dimequarterly.tierranet.com/article...s_dime_6_2.html

Also from what I understand, NISMO makes an LSD unit for the H190. Justin should be able to verify that.

The H190 is a Borg-Warner product btw. H190 LSD came originally in the 720 pickups, but they're hard to find as most are fitted with the salisbury-type C200 diff. The 720 pickups that have the H190 rear end are identified by not having a removable rear diff cover.

I hope this helps. At this point the discussion has shifted completely from "Handling" and now is "Drivetrain", so I'm moving it to that section. It's not necessary to keep pointing out that there's no camber change with the suspension travel on an SRA car.

LeegamerFair enough.  I do, however want to hear reasons for putting an H190 into a Z31...so, Carlos...my ears are open.

 

Rear camber sucks when your trying to put power to the ground and keep it there. so what happens when you lower a truck height Z31? you won't be able to put the power to the ground effectively and you'll wear out tires even faster because of the stupid IRS design and may even spin tires because of it. I plan on lowering thr Z 3.5 inchs but i can't due to the sucky rear end design.  

if it means I have to swap the guts from the H190 so be it. I don't want camber when I lower my Z plain and simple. I mean, i guess i could use the S13 rear end swap but I'm not sure about it. I want my rear end to feel stable at high speeds not drifty or sloppy because of camber.

LeegamerOct 12, 2009, 10:14 pm · #29

Thanks for the info Arro.

I was aware of the Nismo LSD for the h190...but let's face it, they're not too easy to come by, unfortunately.

I hadn't heard of those Torsens that Topgear was making...but that was 3 years ago, lol.

I think I had read somewhere about modding R200 innards to fit in the H190 housing...I'll have to see if I can find some more info on that.

I know why you want a SRA VS IRS, what I was asking is why use an H190 instead of something with a larger aftermarket like a Ford 9 inch, which...by the way is what is beign used in that 7.8 Second Z31.
ArroOct 12, 2009, 10:24 pm · #30

Jeff he's right, the question isn't over solid vs. IRS-style diffs, it's over the H190 solid axle diff vs. the Ford 9" solid axle diff. I did read somewhere that somebody felt the expense of an LSD for an H190 is about what you'd spend for a Ford 9" which will hold ridiculous power.

Hmm...I do wonder the differences in weight between the h190 and the Ford 9 inch rear.

Adding to my list of research...as it would be cool to have a Ford 9 inch in an S12.

I have a Torsen (Topgear) LSD & love it. Highly recommended if you're spending a bit of time on the track & street. They are 1 way so not as good for dori. 1 piece of advice though is to get the diff recoed looser if you're doing a lot of track work. Mine chewed a pinion in 6 months before needing another rebuild. Checked the oil a week ago after 2 years of competition & there's barely any metal shavings & the oil looked near new.

find me a h190 lsd lol for not a million bux ill buy it
CandellanOct 13, 2009, 10:46 am · #34

Yeah, that's the trick. Topgear hasn't made them for a while, but a few Aussie guys did spy a US based clutch pack LSD a while back. I can't find the post & can't remember the company name, but it worked out to be a reasonable price (about AU$1000 maybe).

mod_mastazOct 14, 2009, 11:41 am · #35

The H190 is considered weak to the R200 is because it's a 2pinion versus the 4pinion R200. If you swap in a 4pinion center(lsd or open), it would be able to handle more torque without killing the spider gears.
