some progress made since these pictures were taken

ok its a 2.0 twincam with standard exhaust and type 9 box with a new clutch
im running an lsd but not sure what ratio

in the wet it just about diffs but is a total no go in the dry the diff is tight

i have another 6.2 diff there from a 4x4 cozzy maybe this would be better

what ratios do you fine people suggest? and where would i find these?

 

oh forgot to mention it has a very long gear its doing 80mph in 5th at approx 2500, 3000 revs

 

sorry its a 3.62 standard cosworth 4x4 rear diff

 

should be 2.0 twincam, MT75 gearbox, 3.9:1

if its type9 you need to state gear ratios to give an indication on suggested diff ratio

Sean.

 

its a standard 2.0 pinto gearbox 5 speed if this is any different? and a 3.9 is usually a push in shaft?

 

depends if its ABS, but twincams are normally ABS, Manual and bolt on Lobro joints

bang a 7.5inch 3.9 LSD from a 2.0 xr4x4 and enjoy

 

7 inch cradle you see
i could change to a 7 and a half

i have a mark 1 2.8i sitting there its bolt on shafts what would be in this? its a 4wd

thanks for the help folks so something close to 3.9 ratio

 

The 2.8 will probably have a 3.62, most V6s did. What do you want to achieve? To be able to go round and round in circles? Just get a 3.92 from a 1.8 cvh, fit the drive flanges from your diff, and weld the bugger up. Plenty of smokey sideways driving.

 

going to take the diff out of my wagon today and crack it open and see what the story is thanks for all your help folks just out of curiousity what ratios are there and what do they come in? may look into changing crownwheels

 

the 2.0L XR 4x4s had a 7" 3.9 LSD as standard. I'm thinking about changing to that ratio on my Cosworth.

 

i seen one on ebay but its crazy money 150 plus postage i think il hold out lol the 4x4 diffs tend to not tighten properly they slacken quite easily my friends have had this problem before my car may be ok with a 3.62 that i have it all depends on whats in the car atm

 

sorry 300quid plus postage id only want to give 150

 

ok swapped my diff the one that was in was a 3.62 and i swapped it for another tightened 3.62 but it didnt seem that tight not happy 60quid down the drain was able to diff in 1st gear with 3 in the car

would love to know how to tighten the diffs myself? does any1 know? few chaps i know talk about putting pennies in

 

the 7" diff is a waste of time for what you want it for ,
get a 7.5" one and i ll tighten it for you, it ll be Ł100 but

 

you'll be alright mate but thanks for the offer i tightened my own diff for 20p!
