Hey calling all 380 guys who are serious about puting some power through the front wheels.

I put a post up on the US 9G forum about a Quaife diff to fit our cars & they said they have been through it before & Quaife America will do a Galant (380) version if they got an order for 10 of them which they didn't originally. Anyway I said I would if they wanted to revisit it & so far we have 2 definites. So if anyone else would like to go that path let me know & we'll see if we can help get this up to 10 so we can all have a geniune indestructable LSD for our beloved 380's.

how much

Probably the same as the Magna one, about $1400...

Arnt the gearbox's the same as magna's?????????????? The manuals are just magna box's with 4.11 diff gears in them instead of 3.7 gears anyway

so will these go in the tippys as well

I would love to get one:cool: , alas financially unable to get one:rant:

so will these go in the tippys as well

it depends on the half shafts etc, best bet is to start googling info to find out really.

how much
The US guys are talking $1000 USD plus frieght obviously.

If anyone can confirm this to definately be the case I think after looking at the Quaife thread in Tech Torque we would be close to having 10 without the US boys.

Hmmm looks like this thread died a natural death, guess I'm on my own on this one. The US 9G forum thread has stalled too. Looks like no one is real interested in developing any parts for the 380/Galant ....... no demand.

I'm sure the TMR-380 has an LSD so someone must do one, will make some enquiries at TMR.

Nope, it's auto and has traction control unfortunatly :cry:

Bummer, traction control is useless in my 380 thats why I want an LSD. Wheels spin & the light just flickers on the dash when I boot it.

Just wondering if anyone can help??

I emailed Quaife America & asked about a diff for the 380 & they sent back ........ "Is your transmission a Mitsubishi built transmission? Or built by Aisin?"

Does anyone know the answer to this????? I have no idea!!

trans model:

manual:f5m51-1-s5p

auto:f5a5a-4-c5z

dont know if it helps.

Googled all variations & got nothing ...... hmmm

Googled all variations & got nothing ...... hmmm

Reckon you should email MMAL. Never know, they might actually provide some useful info for a change LOL

Or built by Aisin?

They must be refering to where its made, coz Aisin's live in Aisya :D

I've been looking & the F5A5A prefix is the same as the Galant & Eclipse 3.8L transaxles so I'm assuming it is Mitsubishi & have emailed Quaife back with that info.

Ok More help needed, this is Quaifes reply ....... "We know the 6 speed manual diff does not fit. We have not tried the earlier diff. We would need to know your axle spline diameter and count." ....... Anyone know the answer to that??

Pull a drive shaft out and measure/count?

dont know doesnt say anything in the workshop manual:doubt:

This is all starting to get too hard.......maybe I should sell it & get an Evo x instead :doubt: :confused:

Spot on the money there.

Why spend heaps of money, effort and time to essentially just polish a turd.

Start on a better platform, one that was designed to be tinkered with.

that is a really stupid comment :nuts:

Seriously, since when has a 380 like Foozrcool's been like polishing a turd? WIth the mods that he has done already WITHOUT spending much moolah, could quite easily wipe the floor with a few "faster" cars

Its a figure of speech mate, he didn't mean it in an insulting way, deep breaths :)

I'll admit i've thought about doing the same thing, but while the evo x would be much easier to modify and get allot of performance out of, people are not gonna look at you and wonder what your driving when you give it some up the street, they are just gonna think meh it's an EVO.

Right now people look at my car and think wtf is that thing, thats the effect i'm after so what if a twin turbo R34 GTR is miles quicker than me i like my 380 and aint changing it.

Same.

I get a few cars drawing up alongside, after I've squirted it, wondering what the hell it is.

Good on you. If you only want a fast car, go with one of other mainstream things - but if you want something different and unique, mod a car that nobody else mods. Although I see more and more 380s on the roads these days (compared to when I bought mine), I still do not see many with decent rims or anything worth giving a second glance at. And I've had a few looks with mine too, which is always nice.

Don't worry I haven't totally given up yet.

Need to find someone (maybe a Mitsubishi tech) that can shed light on the factory ecu, diff specs, etc etc otherwise any mods from here will be difficult. The ecu controls half the car & the CEL comes on at the slightest wiff of someone getting adventuous with mods. Need the software & protocols to upload the ecu rom & have a play.

I also believe I need an LSD before I go any further as its getting difficult to get the power to the ground. Anymore mods will just be wasted in wheelspin. The only way the TMR probably gets away with it is it runs the standard exhaust manifolds so the torque down low isn't as full on as with the extractors. Once you're up in the revs & the power is building it isn't such an issue. Mine can be a bit of a handfull on the highway pulling out to pass at full throttle when the auto kicks down a couple of gears. Doesn't feel entirely safe .... LSD needed.

I'm thinking I might try talking to Alan Heaphy at TMR as obviously they must have hacked into the ecu to get the supercharger computer talking to it all with no CEL.

speaking of the CEL guess who reared it's ugly head tonight....i don't know if it will be possible but will ask when i get it tuned if they can remove it...it's only really an irritant as it's not retarding the engine at all and everything is still going strong.

I installed the single O2 spacers a couple of days ago with no success, will order another two & try that. Like you said it has no affect on power just annoying, mine has been lit up for several months.

Something that may be worth considering re the TMR;

Maybe just a remap with adjusted throttle/wheelspeed sensor/spark control/throttlebody opening, changes to limit the wheelspin.

I'm assuming all that could be controlled with just software changes only on a dyno (and time) (From TMR's point of view - you dont need a LSD if you can control the throttle opening with software, regardless as to how hard you stomp your foot).

This assumes they are fly-by-wire, never looked, otherwise it'll be just a little harder.

Yep they are fly by wire & yep TMR did remap the TCL. Problem is getting access to the software & someone with the knowledge to do it :doubt:

so whats the latest on these lsd

No latest atm, Quaife US stumped me with the shaft diameter & spline count & I haven't got around to ringing TMR yet to see if they can help.

Concentrating on my O2 sensor problem & CAI atm then will persue it more.

hows that going with the o2 sensors. ive been thinking weather risistors would help.

I rehashed the setup a bit yesterday & cleared the CEL. I have to go to Toowoomba in the morning for work so I'm taking the 380 to see how its goes. The light usually comes on after a longer trip with a warm restart so this will be a good test for it.

With the CEL, you guys are only having it come on after modding the car yes? why not just remove the bulb of the damn thing? :cool:

Thought about that, have you tried pulling a 380 dash out???????:nuts: :shock:

plus its led.

Thought I had the CEL cured today, went to Toowoomba & back, all around town, stop start no light ...... then late this arvo the f**king thing came on again :rant:

I have one more trick up my sleeve, then its jam the pointy end of a screwdriver through it, that'll fix the f**ker!!! :badgrin:

plus its led.

That doesnt matter, soldering iron +5minutes will stop it from ever making light again, but getting the cluster out shouldnt be that hard, that being said i havent taken one out yet in a 380

I was talking to the head tech at my service place (Nundah for you, Rob) and he was saying the 02 sensors on 380s have a very narrow bandwidth and are a problem even with different fuels (ethanol etc).
Maybe investigate getting these sensors replaced with a wider bandwidth item?

Good point, will look into it. A place in the US use these spacers I've tried but actually weld one up & drill a smaller hole through it to restrict the gas getting to the O2 sensor even more. Might try that first.

Calling all you 380 manual owners out there.

TMR have a one off 380 manual helical type limited slip diff which they will offload for $1500 + GST. (Doesn't fit the auto but :cry: )

It is one of two custom made, one went into the TMR prototype & the other sits in a box in Melbourne ready for a manual owner who will part with the cash.

go buy a manual box and the diff in one hit bro! see if they'll do u a package deal . . . s/c and LSD in one :badgrin:

Hey Fooz I think you need to start a Quaife thread so we can track the progress and know where to look for it. I just realised we were in the Economy thread. Us get off topic? No never lol.
You mean like this one 380matey?????????

I have a proper tech drawing of the manual Quaife diff sitting on my desk here, we just need an auto centre to check the spline count & outer dimensions for clearance.

You mean like this one 380matey?????????
DOH! Yes like this one!:bowdown:
