Thank you all so much for your help. Just called MTQ in Malaga, WA. They quoted $1,727.00 (incl GST) for a turbo swap, new oil line and filter and a one year warranty. They also said, depending on the condition of the turbo, they could repair it for around $1,200. I would have to get the turbo removed and put back in again by a mechanic and he said this would cost around $1,000. I will try to find a recon turbo but I like the idea of the one year warranty. The GTX3582 core would be good. Thanks again
