5 WAYS TO MAKE IT BETTER
1 SORT THE HEAD
We’ve already highlighted the propensity for head gasket issues so if you’re unsure of the car’s history then this is a job worth doing. The part itself is cheap, ranging from £35 for a genuine original part to around £80 for an upgraded MLS item. It’s fairly straightforward if you fancy some DIY spannering, or expect to pay a specialist around £500 to do the job.
SUSPENSION MAKEOVER 2
Both models are tidy and secure handlers in standard form, but there’s a wealth of improvements out there to make things sharper still. Upgrading the bushes to polyurethane costs around £125 for a set, or you could go further and opt for a full coil-over set-up. A set of adjustable Spax items for the ZS are available from Rimmer Bros for £880.
SHARPER STOPPERS 3
If you plan on making the most of the performance, perhaps on a track day, then brake upgrades are a good move. A set of improved front pads and discs from the EBC Greenstuff range is around £200, and will provide a noticeable improvement. Alternatively, the beefier brakes from the ZR 160VVC model can be fitted to a 105 or 120 without modification.
MORE PERFORMANCE 4
Depending on your budget there are endless possibilities here, from induction kits and sports exhausts to full engine transplants, but an ECU re-map can bring useful gains without breaking the bank. K-Series specialists, Kmaps, can provide a re-mapped ECU from £239 which promises power gains of up to ten per cent, plus improved economy and engine response.
LESS SLIP 5
A limited-slip differential helps to get power down to the road, and there are various routes to getting one fitted. One is a brand-new LSD from Quaife which fits the PG1 gearbox and costs around £700 plus fitting. Or you could source a secondhand gearbox and final drive from a 200 BRM LE or other Rover Turbo model. Have a chat with an owners’ club or specialist for in-depth advice.
