Wanted, as above for the Streetwise VVC.
Remember the ZR160 box does not have a Torsen Diff in it, but the BRM Box does...

I'm not massively bothered about the diff, more the shorter ratios.
How much for the 160 box?

Does the 160zr box for the V6 engine? Is there much of a ratio difference?

No, it won't fit a v6, different bolt pattern on the bell housing
If the bellhousing is swapped can the ZR160/BRM boxes be put on a 180? I assume they can but wonder how they'd hold up to the torque?
And thinking this would definitely improve acceleration, but much? And at what cost of top speed...
ZS180 Ratios:
Final Drive 3.94:1
1st 3.17:1
2nd 1.84:1
3rd 1.31:1
4th 1.03:1
5th 0.77:1
BRM Ratios:
Final Drive 3.938:1
1st 3.938:1
2nd 2.23:1
3rd 1.750:1
4th 1.033:1
5th 0.848:1
Not sure what that equates to in usability though? :)

You cant swap the bell housing on it's own, if you wanted BRM ratios the easiest way would be to start with a turbo T series pg1 and build it using BRM internals, I think it might work quite well in a 180.
Brm ratios are ***** with the 3.9 fd. ***** on the road, and ***** on track (Knockhill, so short track at least).
Change the final drive to a 4.2 from a vvc box and its a lot better.

Seems like a lot of hassle, better getting a 160 box and dropping the BRM Diff in?

A 160 pg1 wont fit a v6 though.

Oh yeah of course, the bellhousing again. *facepalm*
