Thanks for the welcome, ayee nothing wrong with the hatch lol, im from Birmingham..no doubt theres some ZS owners this way too..

As for future plans im hoping for a custom manifold, full exhaust with dual exits and maybe a 270 piper exhaust cam and Z&F Remap.

Will be interesting to see what it does with all that lot it will deffo be quicker than a 180 then,and having driven the vvc and my own 180 I would say there isn't a hell of a lot in Pete.very different power delivery but damn quick.

I'm thinking that the lighter vvc would offset the extra bhp of a v6.

Very nice Mathew. to the site.

very nice mate and welcome to the forum . Dont think there would be that much in yours and a 180 . I had a little play with a 160 zr a year or so back now and to be fair not much in it at all dont know if the 160 was standard but my 180 is

I worked out power to weight ratios of 160ZR and the 180ZS and they the ZR was down by 1bhp per tonne, so think the zs160 would be down by 20?
Dunno if its enough to notice though.
The torque to weight will be down though
Nice conversion though. And won't be many around either!
And the XPG is nice!

I like the idea of a VVC ZS, have been thinking about building one but have a few too many projects at the moment. Probably with a turbo bolted on, a cage bolted in to go racing in our MG series in Auckland.

Indeed, ZR160 (137.1 hp/tonne) and ZS180 (137.7 ) very similar power to weight, but the big difference is in torque to weight, where the 180 easily wins (186.8 N.m/tonne, compared to 152.0 for the ZR160). Both have similar gearing and identical tyre sizes (from the factory), the biggest difference is that the ZR requires a 4.2:1 FD to end up with a similar 0-60 time as a ZS180, which does so with a 3.94:1 FD. The ZS's in-gear acceleration is quite a bit better.

These would drop to about 128.2 hp/tonne and 142.0 N.m/tonne for a ZS160. All this suggests to me that you may get close to the 180's power to weight with a few bolt on mods to the VVC ZS, but you won't get close to the torque to weight without some serious modifications.

However, it is a great way of getting 80% of the performance benefit of a 180 out of a 120, without the former's thirst. It is a shame MGR didn't do one from the factory, a ZS 160 to go with a ZS190 would've been a much more complete range, just needed the 2.9 KV6 that was underdevelopment to complete the lineup.
