The reason the P.O. said to warm up and cool down the engine goes back to early turbos and before synthetic oils. You never want to operate a turbo without full oil pressure so that's the reason for a warm-up period. Not really an issue on Deloreans unless it is VERY cold. As far as cool-down, on older turbo installations the oil would burn inside the turbo and "coke up" the insides. After a while the oil just would not get through. Again this is no longer a real issue with synthetic oils. It can't hurt to do it but it is not as important as it used to be. Unless you live right at an exit ramp to a hiway by the time you go through local streets to your house you should be alright. The motor will not "blow up". What will happen eventually is the turbo will get plugged up and not cooling AND lubricating oil. The turbo won't spin long at over 100,000 RPM's without oil!
