Default CHAPTER 10-E - KV6 2.5 220s (6 cylinder 32 valve, supercharged with 224ps /220 bhp)

KV6 SERIES 2.5 220S

ONLY FOUND IN THE AUSTRALIAN MARKET ZT/ZT-T 220S



FIRSTLY, IT SHOULD BE STATED THAT THIS CAR WAS NEVER SOLD IN THE UNITED KINGDOM OR IRELAND. And with good reason but we will get to that....

A $10,000 extra in July 2004, well Australian Dollar, which was about the same as about £6400 roughly in 2004 exchange rate. Based on the 180ps/177bhp engine (not the 190 strangely enough), the high efficiency, low-boost twin-screw type supercharger had been developed locally through Sprintex Superchargers based in Perth, Western Australia.

This conversion involves the replacement and inclusion of a number of components, including a a fabricated inlet manifold to replace the original unit, control ECU, boost bypass value, a secondary fuel injector, mounting brackets and of course the twin screw supercharger.

The low boost will help prolong the life of the engine.......... or so they said. Multiple failures and recalls due to lack of fueling, not enough oil flowing correctly in the engine, additional oil sumps for the charger the list kept going on and on.

Basically MG-Rover never signed off on the engine in the UK but that doesnt mean there are not examples of it in ZS and ZT cars, but they are very rare and the cost is simply staggering compared to buying a V8 ZT for example.

Engine technical details....

• Engine Type: KV6, 6 cylinder, 24 valve, DOHC supercharged (twin screw)
• Displacement: 2497 cc
• Bore Stroke: n/a
• Compression: unknown
• Max Power: 220.9bhp @ 6500 rpm
• Torque: 288Nm @ 4100rpm
• Acceleration: 0-60mph in 7.1 secs
• Top Speed: 145 mph
• Fuel (urban): n/a
• Fuel (extra urban): n/a
• Fuel (combined): n/a
• Emissions: n/a

It should be noted the towing weights are unknown as the car was never tested for uk requirements.
