Had one years ago but sold it.

Now need to buy another but cant remember which one i need.

Anyone help me out or even better still - anyone got one for sale?

 

I'm on the lookout for one too. Copied from another post but I believe 2WD needs a 3.727.

3.25 = 39/12 = MA70 Group A (Special race class)
3.727 = 41/11 = MA70 3.0 GT turbo
3.909 = 43/11 = GA70 M/T, most MA70
4.100 = 41/10 = JZA70 M/T and some A/T, some N/A MA70
4.300 = 43/10 = GA70 A/T, also some MA70
4.556 = 41/09 = GA70 GT

Im pretty sure my old one was 3.9 version but i sold it to Ade before i even got to use it

whats everyone else got as there are a few who use them on here

 

Mines a 3.727 41 crown wheel teeth and 11 pinion teeth lsd type. It's the closest cosworth ratio one

 

From what I've been reading online the '86 to '89 diffs are a true clutch type LSD and the '90 to '92 diffs are a 'torsen' type which are not meant to be as strong or lock up as well




Can anyone on here shed some light on this ?

 

I have to say I've a mate with a 550 ish bhp rwd saff with an elite sequential gearbox. Mostly used on track but a road car too. He fitted a supra diff the same as mine witch is the later type after breaking about 4 cosworth diffs. He drives his with 0 mechanical sympathy and it has been fault less. And it leaves 2 black lines lol

 

actually that is the one i used to have - gonna have to get another. I remember now as it was the closest to the cossie ratio.

 

So next question - who has one for sale?

 

Hi what ratio do you want
Mark

 

Hi Mark,

Whatever is best for cossies - i work on computers - dont know about gear ratios

 

LOL
is it 2wd
do you want it to accelerate the same or a bit quicker


mark

 

Very interested in this too

Mine is 2WD also...

 

2wd and want it to accelerate quicker but still want to hit some speed down the straights

although i doubt i will ever take it more than 150-160 anyway so acceleration is more important

 

3.7 or 3.9 then

 

what the difference apart from .2 lol

 

ring 07990 630659

 

Mark, have you ever thought about making your 6 degree beams to take the supra diff without the need for the conversion kit?

 

hi toby
i could do that but was never asked too ,but it wouldnt be any cheaper than kit
by the time jigs were made etc

mark

 

There will only be a tiny bit of difference between 3.7 and 3.9
