Afternoon mentlegen, I've got a Sierra p100 but it's missing the big noisy thing under the bonnet.. Now I've looked into BMW 325tds conversions along with awd audi gear with is a bit more daring. But as il probably only sell it after I've done it all I'd like to go with something a bit more simple and that's where the banana engine comes into it. Has anyone done it themselves? Easy/hard? What box and axle can I use? Any pointers would be great. Ta
