Well its happened again.. Ive done another Gearbox.. :cry:

Sept last year i did a Diff centre in my gearbox and in doing that bit of it went through my hole gearbox and smashed it all up..:cry:

Wasnt to bad as i got another box and was back on the road $900 later..:)

Well its happened again.. Well this morning car started to do funny things.. I drove straight to Mechanic and he said its inside the box.. I then drove around the corner and took it to gearbox shop.. They Said it looks like a Diff Centre and said do not drive it or ill make it worse.. At this stage it looks like its done a diff centre agian but this time its not as bad as last time.. If i drive the car more it will end up chewing all the gears up and be a mess agian..

Wont have the real answers till Wed once the box is opened up..

SO.. AT this stage if it is the diff centre then its time to get a LSD...

I want to know who has put a LSD in there Box and what sort did they used and what did it cost you..????

Any help will be good..

Man i feel your pain only that ive done 1 box, Auto but ive been told that it will do it again and again.
How do you drive the car, ive got one in mine from mitsu when i got the box to get a reco box was 1850 with labour, and it costed me about 590 for an LSD which is great on wet roads and around rondabouts, but the bad part is its hard to do a burn out but we dont do them on the street only on the track......:confused:

Best of luck.

I dont think it has a lot to do with having an LSD or not having an LSD. If you drive it like you stole it nothing will last.

If you get an LSD won't give you a reason to flog it even harder as they aren't the strongest unit around. After talking with other people in the know once i started to get into the drag racing scene, they told me still to be careful. no big burnouts and not to corner hard with sticky tyres at the end of the straight because its not that strong.

As far as i know (not being a ralliart owner) only the manuals came with LSD's and the autos with traction control.
But that said, i dont own one, nor have i been in one... :)

All good mate.. Done three burnouts in the two years i got the car and two of them where on the strip..

I havent dont anything half stupid for over a year or so.. I drive like a grandma 95% of them time.. Everyone needs to give it some gas every now and again.. I dont do anything silly though..

Ive done some research today and plenty of people have told me the diff centres are the let down on the magna manual box.. other than that the boxes are okay..:badgrin:


BTW you lot aint helping me. I want to know who has put a LSD in the car and what brand did they use... Not who reckons they know why my box broke..:nuts:

I'm extremely interested in knowing what the limitations of the magna manual box are - and what can be done to improve their chances of survival.

I've done some research - and as far as I can make out, the "street" version of the cusco LSD is the cheapest LSD option available, and probably the best for all round use - comes in at around $1500 or so.

I made enquiries with a local mitsi dealer regarding the ralliart lsd, and was told that there were none in australia, and the price supply alone was over $2000 (I stopped listening at "two thousand......" so I can't remember the exact cost lol ). I've considered trying to find a wrecked ralliart gearbox - but lets be serious, they only made 500 to start with, and less than that are going to be manual anyway........ so the chances are slim to none.

At this stage - I'm planning a cusco LSD and some form of modified exeedy clutch, but can't find any info on how much power that configuration will safely be able to handle......... but I guess it comes down to how you drive it more than anything else.

Hope that helps ya out abit egs.

Sorry to go offtopic, but I thought the Ralliart manual gearboxes were the same as a standard Magna gearbox?

BB - I can get you a trade price for a Ralliart LSD if you like (most probably can't supply it for you, but can get you a price to see if you're being ripped by mitsu or not)

The cusco job is probably the way to go.

Nice to hear your keeping it sane most of the time!

I can't help in-so-far as the installed LSD goes but maybe check ppls profile & then PM them. Not everyone goes to the trouble of reading all the threads on here.

As far as your problem is concerned, seems your breaking boxes since the 20's were installed. Coincidence: maybe. Or there is some other component (wouldn't know what) that is causing the problem. The only thing I can see happening with a LSD diff is you would put MORE stress on the gearbox.

Matee, good look with someone posting info on an installed LSD. Someone soon will show you the love.

Apparently its not flat changing that does it... Its pushing it through corners that puts heaps of strain on the diff center.. I was mistaken..

But does anyone have a decisive answer to wether or not a LSD would be less likely to break when things when "pushing hard thru corners"?? I'm assuming thats what they're designed for, but would like to know for sure before committing to purchasing one.

Still trying to work it out.. I dont do burnouts or dump the clutch.. very hard on 20`s..

The gearbox shop told me anything in a straight line is putting strain on the diff centre.. I am asking the same question.. a few people said mits LSD`s and diff centres are weak as..

Dave from RPW says he has never had a problem witht the Cusco and he has had it in there for a few years and has 400HP+.. but my question is he only hammers it in a straight line..

I dont do rally driving in my car as its not ment to go fast as its wheels are to big and car is to low..

When i say i corner had i mean i power through long corners.. thats all i can figure the problem is..:D

Matthius
16-05-2006, 04:41 PM
If a diff is breaking during cornering then usually it will be the spider gears, as one will be flying and the other going much slower, IF this is the problem an LSD usually makes the diff much much more resilient. If the problem is crown wheel/pinion related then the LSD wont do didly for strength.

Correction there

The magna has raced at barbagello raceway, done two classic challenges, two motorkana events.

I think I have the only Magna that can drift round corners:bowrofl: proved that at the classic challenge.

Honestly, unless you have the hp I have, you will be very very unlikely to ever damage a Cusco LSD unit in a N/a magna. The only time I damaged a Cusco unit was trying to use my stupid street tyres on a fully prepped track and when I launcehd the car, had a case of grip - slip, grip - slip, grip - slip with lots of bouncing which with boost on and off broked four teeth off the LSD gears and got into the rest of the gearbox.

Otherwise woudl be today using the exact same box as the previous four years. We just popped the LSD with new gears into a 2nd hand gearbox and bang ran it over the dyno at 450hp at the hubs and not a problem at all. Since then did some racing at Barbagello, and several drag events.

Stock magna diffs, breaking all the time. Get at least 2 enquiries a week on them. The ralliart diffs are also breakign as well as they are better than non LSd models, but are thin walled due to them being designed for an FTO not the Magna torque range adn when they get pushed very hard they disintergrate. Sold a few LSd to ralliart owners who have been forced to upgrade.

Try speaking with Adam - Velocity as he has one in his car. We are fitting another one next week - also hop onto the MOGWA forums and ask the lancer people as we have fitted the same type LSd to a lot of lancers and they can give you some positive feedback on them as well.

Yeah what causes the diff centre to let go anyway.. i wouldnt say i drive the car that hard..

Im just thinking LSD as i always wanted one but is it going to happen again.. this is my second diff to go now..

Some people are saying its my wheels..
What do you think Dave..?

16-05-2006, 05:25 PM
a possible problem with your wheels could be too much grip, with say 16's 215's youd be able to spin it before it strained the box, with 20's and wider tyres im sure all the starin would go into the gearbox as it wont freely spin. id also have a look at the pinion angle of the diff compared to the driveshaft. I know on many lowered WRX's the difference in pinion angle cause smashed diffs and driveshafts even when driven sedately.

It spins 20`s with ease so i dont know about the extra strain..:confused:

I have got people who have stock 17" rims breaking diffs. The commen link seems to always be when someone has turned a corner and accelerated, this is when the stock differential is under the most strain.

It just seems to be a weak link in the box and some do it, some don't. My suggestion is to avoid it, don't do any static burnouts ever, don't accelerate hard around sharp corners with more than say 30 degree angle. Tyre size I can't really see being a factor at this stage.

We use the MZ style LSd for street cars, quieter and cheaper than the RS type whch I run in my car.

So hard launches in a straight line aren't a critical threat to ones diff?

If it's not your diff/trans thats gonna break, doing burnouts with the wheel turned/taking sharp corners while accelerating will deffinately see that your CV joints dont last very long too.

I've still got some concerns regarding the limitations of these transmissions. Lets for argument sake say we are talking about a 5 spd manual magna which is making considerable horsepower.

I (sort of) understand how upgraded clutchs, fly wheels and LSDs fit into the equasion....... but I know of a certain magna driver who has broken their spider gears (no prizes for guessing who lol ) on two occasions. As yet - I can't see the link between this phenomonon and the available upgrade options of LSD / Clutch / Flywheel. The best theory I've heard to date is that upgraded clutches (more specifically button clutches) can/will break gears because of the extra strain they put on the gearbox internals........... so is an LSD going to reduce that risk at all? If not, what (if anything) will?

Redav
18-05-2006, 11:35 AM
As far as matching a Cusco or Ralliart LSD to a transmission is concerned, it wouldn't matter if it's a 3.0l or 3.5 would it? i.e. essentially all the same hardware? I know I'm not aware of a 6G72-S4 owner with an LSD fitted. From what I can tell it's 99% 6G74 owners.

fitment of a cusco LSd will eliminate any real possibility (Unless you have in excess of 300hp at teh flywheel) of ever damaging a set of spider gears again because the LSD has much stronger ones and a different setup.

The main issue that I have seen for causing stock diffs from breaking, has always been someone turning a corner and accelerating hard when they are on a tight angle. Every person who has come to me except for some idiots doing consistant burnouts everywhere, has said that this is where they broke the differential spider gears.

A stronger clutch will exasperate this only because it bites in harder, but in a straight line there is no side loading on the spider gears because the wheels are being driven in the same direction, same speed.

The problem only occurs really when the spider gears are trying to accomodate different wheel speeds IE turning a corner, and are also loaded up under power at the exact same time. This is when they break

Let me re clarify then - 300hp and in excess of 300 - 350nm torque
300hp n/a is not going to break a cusco lsd. 300 hp + turbo possibility but only if you do something really really stupid like try to race at a national drag racing meet with street tyres and get a lot of axle wind up etc.

I highly doubt that you would ever break a Cusco LSD diff on any normal road simply because unlike a normal diff, once you get to a certain level of power, the spider gears become solid and don't take any stress when the LSD kicks in even round corners under hard acceleration. That is why the LSD is stronger.

The reason why the Cusco unit is better is becaue its a clutch pack style unit and once the clutches are engaged, the spider gears become immobile.

This is differnt to the factory mitsubishi style which is a gear style (Qauiffe) style LSD which uses gears only no clutch packs. Smoother to drive but more suspectable to damage. So saying that the factory LSD are not anywhere near as strong as a Qauiffe brand.

This is differnt to the factory mitsubishi style which is a gear style (Qauiffe) style LSD which uses gears only no clutch packs. Smoother to drive but more suspectable to damage. So saying that the factory LSD are not anywhere near as strong as a Qauiffe brand.


Funny then how Rob Chadwick raced his magna sports for over 6 seasons in GTP production racing and never once blew a diff/gearbox and he was using the same LSD as was later fitted to the ralliart magna (It was MMAL's way of testing the product for durability before fitting it to the ralliart magna).

True but you are talking about a proffessional race driver who is not out there doing things that some people woudl do on the road. I am not saying it is not a good lsd, but when they are breaking on the road with people doing other than responsible driving, then it is something to notice.

I don't know about Kormex its not a brand I know anything about but logic woudl dictate that its better than standard.

Well dave his used ex race unit was in my car for over 3yrs before it finally gave up and trust me i did a sh*tload of burnouts, motorkana and track days etc with it
(just ask lord seafood bout my burnouts and about how hard i drive my car) and dave you know as well as i do that full race conditions with slick tyres etc would put alot more load on a gearbox (and all the car for that matter) than 99% of road users.

I know its in ur interest to sell a brand than you market but dont bag the factory unit when it does the job for 99% of the people out there. Oh and if its irresponsible drivers that are making ralliart LSD's die then that is there problem not the factorys (at least MMAL went to the effort to fit one to a magna at all).

Anyone can kill a factory cars driveline thru beind a di*khead with there driving.

I guess all im saying is i hammer my car and have had a good run out of the factory style unit and until i can see a big difference by me using a mechanical plate type LSD, i wont change over. All is good mate :)

I am not bagging the mitsubish product at all. I am simply stating what we have seen, heard and found. But if you are asking me to Recomend a LSD, well value for money then the Cusco is way ahead of the Mitsubishi geniune unit. Thats all I have ever said.

IF you are talking 300hp at the wheels, then you are going to have no traction whatsoever, even with a LSD. In that case you can't really damage the diff or gearbox cause you are just going to spin wheels.

Only real time it owuld be an issue is if you were say at a drag strip with a FULLY PREPPED TRACK, not a normal wednesday night meet thing, and if you had really crappy street tyres and if you had a lot more torque than a 300hp n/a engine would have, talking here turbo time.

Then if you get massive wheel spin with lots of torque say on boost, you could damage the spider gears in the LSD like I did. But it woudl be unlikely cause if you had that level of horsepower you wouldn't even bother trying to drag a Magna turbo down the strip unless you were using slicks cause it woudl be just shocking.

Otherwise as a street car, I could say CV joints but I still have stock origonals in mine. FLywheel is probably next weak link, but even once that is replaced with a billet one like we now have, probably as always clutch is going ot be your weak link.
