Vx Berlina wagon 3.8 litre V6 ecotec
Hey guys I recently blew my diff and wondering if you can swap a whole diff housing from a m78 to an m80? I have a vx berlina wagon ecotec and I’m able to get a “high performance 3.46 diff” from a v8 adventure. I think mine is a m78 with 3.08 gears and wondering the housings are the same to just unbolt and bolt the new one on?

I believe there is a bit of difference between the 2 Diffs, however never had to change the model of diff,
There is another thread I have read, I think it was a reply from immortality that answered another members query.
Only ever replaced one for one. [same model and ratio]
If you do replace the Diff ratio,
You will need to change the PPK in the Instrument menu.

Remember to change the PPK, otherwise you speedo will be out,
and you don't want any warranted fines in the pandemic/economic crisis we are in.
