Which Differential should i get? all sugestions welcomed

[1993Redhatch240sx]

Hey wasap, its my second post, i want some feed back, i heard that i can use a R33 limited slip differential on my 93 240sx. im not quite sure if the gears are the same, i just heard, i heard its a helical LSD. i can get it for around $250. or should i just go with like a used clutch type for around 550 - 700. has anyone riden in a R33 Diff, IM NOT LOOKING TO DRIFT, i would just like to grip a little more , than this OPEN DIFF..., which one would give me the best grip for the buck, or are they the same, should i get the r33 diff now, or should i save up and get a clutch type later. all sugestions and advice welcomed. thanks.

Try getting a LSD from a S15 Silvia, they're helical and around $500, but then you would be $200 away from getting a Nismo or Kaaz drop-in unit. I'm just going to get a J30LSD probably. I'm not a drifter, just an autocrosser, so any amount of grip is better than nothing.

[1993Redhatch240sx]

how much better is a kaaz than a helical? if its a lot better, i mean like its not even close, then i should just get the kaaz then huh? um.. will the R33 Differential fit my car and still have the same gears?when i take some turns, and i give it some gas, dang , i hate that open differential feeling, yeah, i liked your imput

I would tend to think that a helical would be better for grip, because It is torque biasing, so instead of simply locking up when one tire slips, it would reroute the power to the tire with grip. Also, the helical one must be shimmed and used in the stock pumpkin, several gears swapped, ect. I actually rode in a car with a kaaz last night. It was loud as hell. the clunking was rediculous. To quote somone from this site, it sounded like "someone was hitting the diff wiith a baseball bat"

[1993Redhatch240sx]

oh really, so the differential, will not just pop in huh?. so i might have to do some work, but thats what i was thinking of getting a R33 Diffential, becuase they " SKYLINES GRIP LIKE HELL" so hahahah. thats what i want, more grip, i can get it for 250, so i think i might get the R33 differential, thanks

oh yeah, thanks for helping me with my over heating problems, yeah i knew i recognized your name, hey thanks, and peace out

helical is better for grip, ...some usdm s13s came with them, j30, 180sx/silvia, s15, skylines, not sure what s14s came with them, maybe like all se's or something? and an aftermarket example being the quaife unit

[masticatingcow]

Don't buy an R33 differential because the car it came out of was a grip monster. The Skyline "grips like hell" because of it's computer-controlled all-wheel drivetrain, not the rear differential.

To my knowledge, helical LSDs did NOT come in any USDM Nissans/Infinitis in the 1990s.

Get a R200V unit from a J30 or a JDM S13/14 and call it a day. No machining, just a direct bolt-in affair. Save yourself the headache. A VLSD is a VLSD.

what about a Z31 lsd(87-up), aren't those clutch type?

[1993Redhatch240sx]

I think i might get the Helical , from a s15 or R33, I hope that i wont have to do much work on either, but anything is better than this open differential, and im a try them out, ill see about how much i can get them.

i dont want a quickie differential, i got time, to mess around with it, hopefully i will get it this summer, dam its getting hot

[Turb0wned]

j30 lsd u can find one at a junkyard.... if u get it off a j30 94 and older u need axles if u get it off a 95 or newer j30 u dont need the axles... its the cheapest way of going lsd i got mine with axles for $175 matter of fact they have me the whole rear end of the car and the car only had 69k before it was crashed in the front and i guess thats why it was at the junkyard

[naed240sx]

Helical is definitely the way to go as far as grip. My friend has one in his jetta, and it nearly eliminated all understeer. There is an ebay seller who has sold multiple s15 units with the output shafts for around 650 dollars. I emailed him about the neccesary modifications and he emailed back. He is very friendly and seemed to know his stuff. I wish I had the email to post up here. To the best of my knowledge, If you buy a helical diff (with outputs), you can swap it into your old diff carrier, get proper sized shims and reuse several gears(to keep ratio's stock). Any drivetrain shop oughta be able to help you out with this. Go helical if at all possible. Clutch type diff's are more unpredictable, and operate on an on/off basis. They also require more maitenence. I have heard that a helical will pretty much never break, give u issues, or lose locking capabilities. I would have gone helical, but I wanted to save my money for some CO's, so i went with a viscous.(it was very cheap, full pumpkin for ease of install). Here is the email address of the ebay guy. I think he may have a few more HLSD's. Good luck

Quaifes 300z differential should fit as well. SCC has one in their project Silvia. I'm not sure what this setup requires (other than a bunch of cash) but I figure it's the same as putting a 300Z diff in the 240 pumpkin. Output shafts etc.

[naed240sx]

Yes, but quaife does make a diff for the s13. Why get one ment for a 300zx when the correct one is made? However, these are around 1500 dollars. Why get a quaife when it a s15 diff is essentially the same thing? The only thing you will be missing out on will be the warranty. Correct me if im wrong, but i just dont see the point in going with a quaife.

[masticatingcow]

Quaife S13 Differential = Quaife 300ZX (NA) Differential. Why would Quaife make a different differential if Nissan used the same one twice?

[naed240sx]

Umm, all im saying, is I looked this up on their site. They have one for the 240. I am not debating the fact that they are the same thing. Sorry that it sounded like that. Either way, its a ripoff.

[Veriest1]

When I looked on their site last (a year or so ago) I couldn't find one listed specifically for the 240sx. Oh well.

Lack of being able to find an S15 diff would be a good reason but I didn't know they were essentially the same design. Interesting.

[TheOne]

ok, so what do you need to install a Z31 lsd?(not the vlsd but the clutch lsd which is supposed to be in the 87-up z31)

[574-240sx]

just buy a regular VLSD. My J30 POS VLSD has worked fine for me.

[ceniack]

i have the R33 rear diff, just a regular VLSD but with a 4.11 gear ratio. try venus if you want one, i think they go for lke 275 (not sure if that is shipped or not though) and i think that is with axles because it takes the 5 bolt axles unless you want to swap out the output shafts.

[1993Redhatch240sx]

ive been talking with a few friends, mainly Grease Monkey and Banzee. theve been telling me that if i am to go with a helical, that it would be best to go with a s15 rather than an R33, but they told me i might have to do some modification or swaping with the s15, you guys told me that with the r33, ill have to change some shims. well before i digress

Which one would be the bests, i would think the s15 becuase its newer. does the s15 have the same gear ratio, i heard theyre 6 speed. so i would figure they have a different ratio, ive been reading all the post, but im defenetelly getting the helical, over this open diff
