1.8 Diff onto a 1.6 car...

Hi guys, my 1.6 VLSD (1989) is on its way out (slight grinding noises, squeaks etc), and I?ve found a Torsen out of a 1.8 1993 V Spec. It will come with the half shafts, and hubs, but will I need to change the prop too? I?ve read conflicting reports, so I turn to you!

Cheers!

yes you will need to change the "prop". the flange is bigger on a 1.8l car

Awesome, I take it the 1.8 prop shaft will mate to the 1.6 gearbox no problems though?
Yes, it works just fine. Make sure you get the nuts, bolts and spring washers from the donor car though, as the bolt holes on the drive shaft and diff are larger as well.
I did this a few months back. Yes its all bolt up swap but you need the diff, prop and driveshafts. Also as mentioned get the diff to prop bolts , nuts and washers as they are larger in the 1.8 car. The hub nut is a real odd size though (29mm) on the 1.6. Might be worth sourcing before you start or use a good meteric equivelant.

Of random note... the axle nut for the 1.8 alxes (at least my single piece 2001 set) is the same as a honda civic Dseries axle nut (found this out when i had one missing and raided the bolts/nuts box). For easy part reference, 92-95 civic ex would work.
also of note: Axle nuts vary depending on year and possibly if they have ABS or not. DOuble check before you start that they match up!
AFAIK the internal thread size has allways been the same. Its just the exturnal nut size that differs 29 on the 1.6 32 on the 1.8
Axle nuts for most subarus also work on the 1.8
