To clear up the confusion about the Cusco LSD for magnas here are the part #s
- TYPE RS 1 WAY (the best option) = "LSD 145 F" about $1500
- TYPE MZ 1 WAY (cheaper but to harsh) = "LSD 145 A" about $1300

The part numbers quoted are for the non-mivec 2.0 V6 FTO that is a fit for Magna.
Part # "LSD 145 F" Type RS 1 WAY is what UNDER8D is having fitted to his car I know this as he qouted the part # here http://www.aussiemagna.com/forums/showthread.php?t=8256&page=2&pp=10
The gearbox model number on manual magna's is "F5M51-1-F5N"
When ordering you need to also get a speedometer drive gear.

Will this LSD fit into an AUTO magna?

if this is true Green is they god

The gearbox model number on manual magna's is "F5M51-1-F5N"
Sorry to hijack, how do you find out the transmission number? Do you know how to find out the numbers for the auto / tiptronics? I'm trying to compare them to the Diamante's from Japan. I'm sure they're the same but I need to make sure.

this L.S.D is for manual vehicles only.

For Automatic ppl I would recommend fitting the traction control system avail on some magna's. This system works like a crude LSD, when one wheel spins the brake on that wheel is applied forcing the torque to the other wheel etc and visa versa..just like an LSD..this brake operated traction control system is also what holden uses on the 4WD Adventra that was unable to run front and rear LSD and centre viscous coupling due to engineering problems and excess torque from the V8)

The gearbox model # for the Invecs II 4 speed auto including Sports Triptronic is "F4A51-2-E5A"
Dont know the model # for 5speed Auto's

Cheers guys

Green, this wont suit the 2nd gen magna's will it?

AH, good to hear mate, but are u sure that these diffs will fit the magna? dave seems to think he got the packaging boxes mixed up, so the number i quoted may not be the right one. also read thru daves post in that forum topic, cos i think he explains in there that he tried the fto diff but it wasnt the right one?????

not saying u are wrong man, but i'd hate for someone to order the diff themselves and then find out it was the wrong one lol

hey dude good to get ur feedback..yeah I read dave's post and dont believe a word, as if he got he got the boxes mixed up, and of course the ONLY avail LSD for Magna is the Cusco FTO unit as these cars use same gearbox and there are no manual magna's in Japan..
if you are unsure contact Cusco's aus distributor www.accessauto.com.au ...Dave would have had to order the diffs through these guys as they are the ONLY Cusco distributor in Aus.
qoute your gearbox # as well.
As for TR/TS manual V6 get your gearbox code and contact the Aus distributor.

hehe, cheers man. sounds like u've done the research then. the only thing that still may need to be considered, after reading thru his post again, is the cv shaft size. by the sounds of it, this is where the problem was to find the right fit. but then again it could all be stories? so who's gonna take the risk and order one in to find out? lol im making some enquiries of my own anyway, just for my own interests sakes, the curiosity is getting to me big time! :roll:

Sorry for the O.T. but is your car back yet Under8d?

unfortunately no :cry: i'll post a new topic soon, but lets just say its now costing me another 1g, cos i broke more than just the diff. not a cheap expedition thats 4sure :cry:

i stress to anyone who owns a manual, nurse your diff! unless u want to forkout a rediculous amount of money like i hav :rant:

Wont be any problems with CV shaft diameter unless you are sourcing an LSD directly from a MIVEC FTO that comes with a Mitsubishi LSD standard (This may fit anyway could just be one of the "stories" us poor consumers are told by supposedly reputable dealers).
We Magna ppl are only interested in an aftermarket Cusco item. Cusco doesn't make special batches so the only one's avail are for us are the non mivec FTO item that uses the same gearbox. On monday will be calling accessauto to get more details as I need one ASAP (dont want to kill another clutch with wheel hop).
BTW under8d wont be any guess work or problems with fitting as others have fitted this item, including yourself to Magna's. Will be waiting for your feedback dude.

Cheers!!!!

NO worries dude. definately sounds like u are on the ball here! let us know how u go with access auto. will be letting everyone know how it goes when i get my car back :D

Are you guys getting any performence outa this? or you replacing your bunged ones?

are they limeted slip ones?

are they limeted slip ones?

Read the title of the post :D

While this is a little OT, will an LSD solve axle tramp (hop) at all? This is driving me banana's on the VRX lol

dont quote me, but i think ive read somewhere that an LSD will solve this.

intresting..... neathertheless

Aren't those nifty engine mounts that RPW sell meant to combat axle tramp too?

I love hopping away at the lights too !! :mad:
axle tramp becomes more nasty when - 1. you get bigger/wider tyres with more grip , or 2. an LSD.
it occurs between the point of grip and wheelspin. the above two increase the grip levels, so when tramp occurs you will be putting down more power, hence it is worse when it happens. also an LSD won't let one wheel spin, so the range in which tramp happens is greater. so the above two will increase the point of launch revs at which tramp will happen, which is good, but when it does happen it will probably be worse - doh.

Who cares about axle tramp, an LSD is going to make the car pull out of the corner better... thats enough to get my accolades.

so what IS the solution to axle tramp.

i havnt had it for a while, but neither the less, id hate to get it right when your about do to a drag run (on a drag strip).. d'oh!

tramp is SO fustrating and even embarrasing when taking of hard at the lights. I think the old way to really combat tramp is upgraded suspension and perhaps RPW engine mounts...

When I used to drag race a bit... it was only 1/8 but it was legit dragging, I only ever got axle tramp a few times, and I was fairly nice on my car and if I went a bit much it was all clutch slippage, replacing a clutch is better then other things.

Hey, howcome it's listed as an LSD for a non-Mivec FTO when MMAL and everyone else says that the one they use in the Ralliart comes from a Mivec FTO?

Because mivec FTOs came with LSDs, this one is an aftermarket cusco that allows you to use your existing drive shafts.

The Ralliart has the thinner driveshafts (like the mivec FTOs).

Does it? That's interesting. I'd have thought that the drive shafts for those two cars would have been thicker. Oh well...

can anyone confirm this? i really need the correct part number before i order one!

Cheers guys

Traction control on a magna kills the throttle and retards the timing to reduce torque which allows the wheel to grab again, the brakes aren't used in this system :)

5speed auto is F5A-2-EZB for FWD and W5A51-1-E1DD for the AWD
