Liam,
I purchased my engine when the 6 Litres were very new ( nearly 3 years ago ) and got everything included, tranny, clutch, slave/master cylinders, fly wheel, power steering, A/C compressor all accessories, loom, ECU remapped and 12 Months OR 20,000K warranty delivered for $15.5k INC G.S.T.
you should be able to get it for under $12k now as you donr need the power streering or A/C stuff. And they are considered OLD
