BMW NUT

Hi everybody , I built a LS1 powered BMW E36 in Sydney Australia. i thought I was leaving the country permanently only to last 7 months in Cebu , Philippines. Now want to live in both Aussie and Cebu. Gave my much loved car to a friend. I want the car back but have not brought the subject up. Will be bringing the subject up next week. Anyhow if I get the car back ,i plan to further develop the car . First thing is a lower ratio diff . Later hope to get a little more power from the LS1 and a lumpy sound.
