7 m clucth fit perfectly
in fact you can put all clutch of 2jz 1 jz or 7M na if you want
7m are cheapiest and there is a lot of stage

 

A couple of options.

You can go with a stronger pressure plate with stock disc OR a 6 puck sprung hub disc which will hold more but be a little grabby at engagement.

 

I've had a OEM 7MGE clutch for well over 8yrs now!!

 

aight awesome, thanxs alot guys

 

...you're wasting your time with anything more than a stock 7mge clutch kit. It will hold 250hp without issue, and you will absolutely regret a multi-puck "performance" clutch on that setup. ...believe me, I speak from experience.

yea, i know, thats why i have come to a split decision, 2 clutches, same clamp force, but different COVER SIZE???

one is 235 and the other 225, whats the difference, i also see that the 235mm clutch says 40% over standard clutch, whilst the 225 says 30%, i have calculated that 700kg is in fact 30% over standard but dont understand the reason of having a larger cover size... can anybody inform me on this??

cheers

$250aud for a performance clutch... that's what, $140usd? Good lord...

Call them and ask them exactly what fits your application.

--billyM

 

is 140usd a too cheap??

can anyone help me with cover size difference??

 

heyas again,

i have another problem...went down to a few local Jap performance shops (Xspeed and Cypher Industries) trying to get a rough idea of pricing and labour, but now the problem:

the clutch disc size, 225mm and 235mm, they both have different spline OD.

I have been told the 7m is 236mm
1j is 240
2j is 240

and the 1g is the same, on the 235mm i think.

and the only way to tell the size is by taking out the g/box!!!

and that they all run different flywheels!!

does anyone know for sure that i can just slap in a 7m clutch EVEN IF the disc size is different??

they way it seems is if i give it to the shop i wont have it for a week or two as they find out wat size, etc. but if i know for sure i can just order it in, wait for it, then take the car there and have it bak the next day!!

thanxs

5 and 7 M-GE is the same.

 

according to the books that both shops have there are different sized plates, which means the flywheels are different sizes, so if i have a 225 and the 7m is 236 its still 1mm bigger than the other 235mm variant, which means, again, another flywheel!

do you see what im saying??

i have a 225mm plate, then it cant be the same, since there are 2 variants....it even says it on the exedy website and xtreme clutches and a few others!

You will have a 225mm clutch/flywheel combination. Only the later 5MGE's had the 240mm clutch.

Just go to Coventrys/Supercheap/Repco and ask for a new clutch to suit a 1984 Supra. You *may* need to trade in your old one, been a long time since I've ordered one. Don't bother with anything 'performance'. It should cost under $200.

.

it makes sense, until Xspeed rang me and told me the 225mm didnt fit, i have the 236mm, which also now means i have to buy the 236mm clutch and i cant return the 225mm, sucks, no Supra cruise this weekend for me!

wog

 

you sure??? since the 5m-ge isnt factory in aus spec ma61's!! but if your sure its 225, then ill go on that. why not bother with performancey clutches, i waant to be able to drive it hard and not have it root itself.

thanxs

I'm not a 100% sure but I'd be very surprised if the 1982 5MGE had a 240mm clutch when our 1985 5ME only had a 225mm clutch.
If you want to be 100% sure you'll need to pull the box off and measure it.

Don't bother with a performance clutch because a) you don't need it, and b) you'll end up breaking something if you use it.
At the most just buy a 'heavy duty' or 'uprated' version of the stocko.

 

mmmmkay, yea i was just gona buy a heavy duty piece, heavy duty will be good for some light track use so i guess a serious clutch isnt needed!

just want something that is higher clamp force but not much harsher on engagement, so i was looking at the Xtreme clutches, or the exedy Cypher was offering!

thanxs peewee

The 225, 236 or 240 NON TURBO, 5m, 5MGE, or 7MGE clutches will all work on the 5m flywheel-the larger covers have inset bolt holes:zzzzz: I am assuming you are surfacing flywheel? If so, then measure it yourself if you need confirmation.

 

the shops told me the splines outside diameter, which means the flywheels are different??

are there any risks with using a 240mm plate on a 225mm flywheel, i guess it just means i need the larger cover, right?

F#k this is confusing, the shop tells me one thing, you guys tell me another, i would expect you guys to know more since we have the same car sorta thing.

wog

 

ok so the 7m-ge is the same as the 5m-ge, ok......how bout the different sized input shaft out side diameter??

225 is 28.9mm
235 is 29.8mm

or so im told, by the exedy catalogue...or is the 7m the same as the 5m on the splines outside diameter??

i want to buy a clutch and take it to the shop to put it, i dont want to find out that i have the wrong clutch, or it wont fit....just want to make sure!!

as long as the 7mge fits the 5mge and you are 1000000% sure, i trust you!

see:

ma61, 236mm
http://www.daikinclutch.com.au/catalogue-details.asp?id=39000686

ma61, 225mm

http://www.daikinclutch.com.au/catalogue-details.asp?id=39000687

ma70, 240mm

http://www.daikinclutch.com.au/catalogue-details.asp?id=39000688

see at right side the Size & Spline OD x No of Teeth is different between the ma61 and the ma70, only some of the 5m-ge's had the 29.8 OD....so if that is the 1 i have i CAN use the ma70, but if i have the smaller one, i CANT use it.

 

w5x series gearboxes had same input shaft size-So I "think" the clutch sellers are confusing 7mge(N/A) w5x applications with 7MGTE(Turbo)R154 applications. You need a "pull type" clutch, with a small input shaft size. Or, there are more choices available in OZ, my info pertains to North America, and I am all wet.....

what do you have done to the engine... if still stock just buy a stock clutch and turn the flywheel unless you have a turbo or something on it

 

CarFreek:

ok i get it, i see how that works, thanxs

engine wise, it has extractors and full ehxaust system, 3" intake pipe (AFM-TB), pod filter and soon it'll get tuned!
im buying a turbo this week, but whether or not i go to the effort to 5m-gte it is sumthin else, i dont think the result will be worth the effort!

wog

 

what kind of extractors do you have? whats available for extractors in aus?

 

http://www.toymods.net/forums/showthread.php?p=844785#post844785

post 49, picture 2, it clearly shows that the clutch cover bolt pattern is larger than the 225mm clutch cover (pictured on the left side), so how is it possible that some of you are using a 240mm on a 225 flywheel, considering the cover wont bolt up to the block??

wog

 

iunno, they were on the car when i bought it, they have no brand on them!! so i dont know much about extractors in Aus, besides im a turbo boi, which leaves me with even less idea!! since i would go to a shop and get it custom made, but they do look mass production, but ill have another lookie tomorrow!

wog

 

Whoops, my bad. Gotta say thats a surprise to me.
You should still be able to return the 225mm clutch and swap it for a 236mm though.
Unless you bought it off the back of a truck.

 

just got bak from Xspeed, listen up bois, the 225mm clutch COVER doesnt line up with the dowels in the block, but the clutch disc fits on the shaft, so that means that i have to buy a 236mm cover to use with the clutch disc, which means, that i have to buy 2 clutches everytime i mess 1 up, because the 236mm KIT has the 28.9mm input shaft OD (which is r154) whilst mine (W5X) has the 29.8mm OD shaft...so now im waiting on the cover to finish my installtion off.
