JONBEE - 6/2/10 at 08:54 AM

Hello,
i have the chance of obtaining a very nice low mileage 2.5 kv6 auto engine.
its still in the car and runing fine.

What i need to know is :-

1 : What RWD auto/manual gearboxes can be used to convert to RWD and how difficult.

2 : What parts from the original car are needed (wiring / black box / immobiliser / ignition switch etc ) and is the immobiliser linked to black box, fuel pump etc.

thankyou all

If it is out a Rover 825 stay well clear.

If it is a 2 litre don't bother it only puts out 140bhp.
A 2.5 has avariable geometry inlet will have anywhere between 156 and 186 hp depending on what model it came from

If it is a 2.5 auto then the flywheel could be swapped the Rover V6 flywheel is a fairly heavy DMF type, and the crank will need a spigot bush fitted. It should mate to a Caterham type 9 bellhousing.

The Rover 75 and MG ZT V6 used a Siemens ECU the Rover 45 and MG ZR v6 used MEMS 3 --- not sure what the Freelander V6 used.

Yes, its out of a 825 sterling.
1996 P reg.
It sounds like its not an easy conversion.
To fit a spigot, i guess the crank has to come out for machining.
What are the reasons you say stay away from the 825?

thankyou all

As BT suggests, don't bother with it. These early KV6 engines were fragile and had a heavy appetite for head gaskets.

The later redesigned KV6 (Rover 45, 75, MG ZS, ZT etc) is a much better engine; head gasket issues are very rare on these.

I suspect they mean you can use the same after-market bellhousing as the 4 cylinder K series in order to fit a Type 9. The standard Ford bellhousing certainly won't fit.

will leave well alone.
thanks all
