the thread happen to come up again and i saw it so, for reference, here is the S54 info from mr2oc

LSD differential, C56 (ZZW30):

It is a helical limited slip differential.

ON another note I have no Idea what LSD came in my tranny for my BEAMS swap but from reading this thread I think a while back we deduced that all BEAMS had LSD right? We just changed the clutch while doing the swap and all 5SFE S54 CLUTCH PARTS FIT.

Read the previous page. We are discussing which Celica 3S-GE motors do come with LSD and which Celica 3S-GE motors DO NOT come with LSD, Yes this includes Beams.


If your Beams came from an SS-III it has LSD, if it came from an SS-II it does NOT.

We're trying to dispell the myths that SS-III means Beams and all Beams have LSD.

SS-III means Superstrut Suspension, LSD and 3S-GE.

Beams is a 1998 revision of the 3S-GE motor, other Toyota models including the MR2 and Rav4 and the Celica SS-II which previously had 3S-GE motors also received Beams after 1998, This has nothing to do with LSD at ALL!

Prior to the introduction of the SS-III trim in 1995, there was some special "SS-II with Superstrut Suspension" models with a differing chassis code to the regular SS-II, this model also came with Superstrut, LSD and 3S-GE.

now 2 have popped up apparently 1994 models,

also if you check the TRD wesite it says the TRD mechanical LSD for non-"Super strut suspension model equipped with viscous L.S.D." even fits a car that "Includes helycal L.S.D. model", so there is a non-SSS model with a helical LSD somewhere http://trdparts.jp/english/parts_lsd_mechanical.html this gets more and more confusing

the LSD on supercharged corolla / levin / trueno is interchangeable along all E series transmission,

the Levin supercharged comes iwth a E58 ( LSD ) transmission, this LSD can be installed in E56 ( same tranny non LSD ) and E153 found in MR2 turbo, Camry V6, Solara V6, ES300. << This is veriofied information and I have both trannies apart in case pictures are needed, internally these trannies are identical, except for the differences in years with some having dual synchros and better oil system. the Stock OEM LSD for these transmission was always viscous, in some countries there was a TRD dealer option, pre 1993 this option was hellical LSD, after 93 the options were hellical andclutch type ( usually used only on mr2s )

if the LSD is hellical you'll see a small ( ~ 5mm wide ) hole when looking insdie the transmission axle area, if the hole is rather large ( ~ 10mm ) is non LSD ) for clutch type, you'll be able to see the clutch discs. and OEM Viscous is easy to identyfy, you'll see the bar and a gear right before the bar, I'll try to get a picture of this.


I have heard that this is also true for s54 transmissions, the diff found on MR-S, Levin non supercharged and aftermakrget LSD made for either of these cars can be used on the s54 transmission but I have not personal experience with this fact.

me thinks you've read that wrong the mechanical lsd for the viscous equipped box has a different part number to the one for the "includes helycal l.s.d model". Its a case of e56 gearbox for the viscous lsd, that makes it compatible with the other e series boxes in terms of lsd, so e153, e58, etc. The helical diff is in the S54 gearbox, which is compatible with other gearboxes like the c?? series that come with the zz engine series. The E and S series are not compatible in terms of lsd.

I'll post what i posted on ccuk as it really is this simple when it comes to what gen 6's came with lsd's. whether it has a beams engine in it or not isnt relevant.

before august 1995

ss 2 without superstrut, s54 gearbox no lsd, single pot calipers

ss 2 with superstrut, e56 with viscous lsd, twin pot calipers

after august 1995

ss2 no longer has superstrut option , single pot calipers, s54 gearbox without lsd.

ss3 now only comes with superstrut, and has a s54 with helical lsd, twin pot calipers.

My SS-II has Beams, no SS and twin-pots.

Sorry to sound like a tool but is there a way of checking without dismanteling the tranny?

then after 97

the SS-2(beams) & SS-3(non & beams) run the same TRD pads, so they should run the same twin pot front brakes
(check Japanese TRD website)...and on Toyodiy (however slight difference in part numbers)

what year of camry did you get that differential from ?

you have to be aware of trans revision, and as you found out, internal parts are not complatible with narrow gears ( newer design with dual synchros as well )

I have a Levin supercharged E58 diff , a Camry V6 diff and a MR2 SW20 LSD diff, and they are all compatible, depending on how my time gets available I'll try to get pics of all 3 side by side.

I think it was 98+ wehen they changed to narrow gears to reduce the rotarting mass and thus make it easier for synchros to bring the gears to speed, at the same time they added dual synchros to also aid with this.



Sorry for nto clarifying about the difference between regular and narrow gear E153s, I totally forgot when I wrote that post.
