Keep us posted on this. I also have wondered about this conversion.Thanks for your reply Kerry, i am on the south coast of oz, a friend did his time as a mechanic on that era of canters, but believes it is doable, he has in his possession a rosa bus, same motor as mine and has offered to sell the gear box and complete turbo etc. Need to do some more research as to how difficult, benefit etc.. i owned and built my canter over the last five and would love the upgrades, buy am happy with it in its current state.
