Hi, I have a G6 which ive done a T conversion on and next step is LSD so I can put the power down. One thing that's got me stumped is im not 100% on the diff it has. Some forums say anything NA has the m80 but I've also read anything with a zf6 has an m86 2.73. Ive checked all the labels the only info they give me is 2.73 ratio which could either be m80 or m86. When I had the cradle out I happened to have a m86 housing and from my dodgy measurements and visual inspection they appeared the same, but does the m80 look significantly different in anyway? Sorry for the ramble I just want to be 100% (im about 80% sure its m86) before dumping $1500, pulling the cradle out and finding I don't have the m86. Cheers!

In factory form you 100% have a Single pegger M80 2.72 which has an identical outer housing to the M86 

 

The G6ET also has a single pegger M80 2.72 as all G6ET’s were ZF auto

 

The 2.72 ratio is always coupled up with the ZF gearbox

So the na and turbo both have the m80?

Turbo doesn't have a m86 open centre?


Does the m80 and m86 share axles/splines?
