I have heard that you can swap the diff from the geo storm 5 speed to the cavy isuzu?? I was told that it was a stronger diff than whats in the cavalier isuzu, i was wondering if this is true or just some random bs.

its true. there were pics of the different gears on here a few years ago...... I've swapped a few of the diff's myself.




SPD RCR Z - '02 Z24 420whp
SLO GOAT - '04 GTO 305whp
W41 BOI - '78 Buick Opel Isuzu W41 Swap

when doing this swap do you know what kind of power you can hold with it??

im wanting to do this on my 2.0L OHC sunbird too... just curious, is it a direct bolt up? no modification to make it work really? or would it just be swapping gears? thanks, dont mean to thread jack, just wondering...

What is the name of this transmission is it a mk.. something or what

Yea, I am running a diff from a 90 sunbird, and a friend of mine used a diff from a 91 Isuzu in his Cav before he sold it

MK7 I believe for the GM....I am not sure what the designation is for the GEO version

You already have the stronger diff. GM didn't start making the weaker diffs until about 1995

REALLY?? Im going to be adding alot of power to it soon.. do you think my trans. will stand up to it?? and is there anyway to make sure that its the stronger one? it had a reman. put in a while back..

yea because the isuzu diff has compressed metal spyder gears and the geo diff has cnc machined spyder gears , so thats nice my buddy took the spyder gears out of his cavi and swapped them with the geo ones , runs fine

Thats good to know.. i got a muncie coming for the car now.. but i think ill do that to the izusu and use it as a spare maybe... thanks, good to know
