MGR had this dilemma with the ZT, a 1.8vvc would have been OK and an option against the 160bhp 2.5. It would have delivered the economy that was desperately needed too, but the vvc would have cost more than the v6, so it was a marketing no go.
That's why they stuck a turbo on a 1.8 in the ZT, it was much cheaper to produce than a vvc, and for the same reasons, marketing a 160bhp zs 1.8 for more money than a 180bhp v6 would not have been logical.
This said, there were a few 160bhp vvc zs's that left the factory.

They were also looking to replace the VVC and use a 1.8T across the range, with the EU emissions laws that were coming in at the time, the VVC engine didnt meet the requirements. Another reason for the use of the 1.8T's was because the tourqe was much lower in the rev range compared to the VVC engines making it more suited to the heavier ZT and 75 models.
ZandF tuning should be able to get round it, specially as they did a lot of work on the engine management.
