just grab a set of nismo bolts as suggested earlier in the thread and give them to the shop when you drop the diff off

Hi. Reading about diff ratios..found this post. Just want to share my experience with my silvia 180sx drift competition car. Using SR20VET engine, N1 cams, GTX30R.

Ive tried 4.1 and 4.3 with sr20det transmission and

4.3...4.6...and 4.9 with rb25det transmission.

My findings:
-4.3 works good on the sr20det trans.
-4.6 worked well on the rb25det trans. Some how rb25 gear ratios are very long especially the 3rd gear.
-didnt notice much difference on the 4.9...maybe cause im.using 18 265 tires on the rear.

Will and R200 6 bolt ABS fit into my s15?

[B.O.X]

I just picked up a skyline diff (48:11 = 4.363) & I have a stock 180sx diff (49:12 = 4.08).

Is it possible to use the crown wheel from the 180sx (49) & use the pinion from the skyline (11) to get a ratio of 49:11 = 4.454?

[sssturbo]

no, crown wheel and pinion are matched sets

[B.O.X]

i thought so. they seem to mesh fine but i havent done a backlash test yet.

Missing from the list:
Z32 non-turbo 2+2/2+0 300zx ratio: 4.083, R200, abs, 2 bolt backing plate, Viscous LSD, 5x1 half shafts.

Short answer "yes"
Long answer "depends", is your s14 r200 or r180? if r200 then you will need to swap the 4 bolt backing plate for the s14 2 bolt one., if its r180 you will need a 2 bolt backing plate & the half shafts & axles will need to be swapped over. Also make sure you have the right half shafts for your axle 3x2 or 5x1
(a n/a z32 ~ good upgrade for s14s i've been told but you need to run the axles as well)

crown and pinion anywhere from 350-500 depends on what people want to pay.

Will a r34 auto viscous LSD abs fit my 94 180sx it's a 5x1 bolt halfshafts no abs
I know I'll need to change the rear hat but not sure if the old driveshafts will bolt up as the r34 one has abs rings on the halfshafts

[xris]

you can always knock the half shafts out and swap them. but the abs diff is longer than the normal diff. so tailshaft length might be too long

[billywhiz]

Does anyone have real world experience of s14 diff vs max speed. Currently have s14 ADM and I’m looking at a new diff to get 1.5LSD + new final drive

Last year I was doing ~235kph (qstarz GPS) at the end of PI straight but wasn’t tracking rpm, I’ve got an extra 20kw, looking to move to R rubber semi’s plus I’m more experienced so expecting higher straight entry speeds – unfortunately had mechanicals preventing entry to PI events this year and don’t want to be pinging on the rev limiter for too long J

Going from theory eg http://www.catherine.../sti/tyres.html, does this look correct? struggled to add a table, so jpg seemed best option

Bought a diff out of a r32 thinking it would be 4.3 ratio. ended up being a single spinning 3.45 ratio!! so watch out.

[Shazz058]

Hi all!

I have done ridiculous amounts of reading and am struggling to get my head around the seemingly infinite number of R200 variants. I am wanting to get a 2-way Kaaz for my Silvia and have no idea what my diff was originally out of and therefore no clue which Kaaz P/N is the correct one to suit my application O.o

If someone could shed some light it would be greatly appreciated

I have:
VLSD R200
4.3:1
5 Bols Shafts

[DriftLoveAE86]

[kdog]

im chasing 4.6 or 4.9's
anyone have one or ideas to get some?

[Frequent Slider]

hey guys,

Am Trying to track down an r200 with a 4.363 with ABS. It also needs to fit an s15, so from what I've read i need to be looking for diffs out of an R34 RB25DE Manual, R33 RB25DE manual, R33 RB25DET Auto. thats correct yea?

[kdog]

ive got the gears and a cusco two way

[Frequent Slider]

does anyone know if you can put Non ABS Crown wheel and pinion into an ABS housing? or is the shank on the crown wheel to short?

[180X]

hey fellas, just bought 5 bolt shafts and realised its uneven length... am i still able to use it on my r200 off a type x?

[blingcommander]

They are all unequal length

[180X]

oh really? i previously had a pair of shafts that were equal length 5bolt. Will the r200 diff still fit on a s15?
