hi all .. would a diff from a 4x4 fit directly into a 2wd rear beam...?? also if they do how can i tell which one it is i have.. ?cheers..

 

no the 2wd is a 7.5 inch cossie diff, the 4x4 is a 7 inch.
the 2wd is around 195 mm wide at it's upper mounting the 4x4 is about 10 mm less

 

so i take it the beams are different?

 

cos 4x4 diff is 7" and the other is 7.5"

 

just ground the rust off the tag on the diff which reads 86bb / aaa 364
A9 B09.. just didnt know if they were interchangable and may have been swapped.

 

7" or 7.5".. from where to where..?

 

the beams are different but it is just the mounting width the drive shafts are different

 

7 and 7.5 refers to the crown wheel diameter not your penis size

 

ok sorry to sound thick im guessing mine is the original 2wd one but where would i measure to and from.. ???

 

measure across the diff upper mounting bolt faces around 195 mm for a 2wd and 185 for a 4wd

 

As Turbosystems says

I've done it, I had a 1/2" spacer knocked up and that was all that was needed

niel how do u get on with 4x4 diff in ur 2wd?


cheers jay

 

[quote="jaycos"]niel how do u get on with 4x4 diff in ur 2wd?


it will have less top end than standard due to final ratio being different

 

but is that all alvyn do get more acceleration?

 

YES more acceleration but you do loose alot in mid and tops!

m8 had one(4x4)in his 2 w/d and the gears WERE noticably shorter and car was screaming after 150+mph etc!

 

youve changed me mind then lol wont be puttin a 4x4 in


cheers jay

 

eh, its 3.62 vs 3.64 which is probably only equates to about a 1mph at 150+

 

my mates fitted one to his recons it pulls a lot harder so i was guna try it but if it nackers the mid range?

 

Surely in addition to the loss of mid and top end, isn't it weaker ?????

 

screaming at 150.... shit mine revving its bolloks off at 100

 

Sorry Jay,

It was a 4x4 cossie diff fitted to a Sapphire 2000E, which oddly had a 7.5" beam

I didn't notice much difference TBH, but the car was shit slow anyway

I think the 2000E diff was a 3.62:1 anyway
