I have fuel injectors, t3/t4e(brand new), clutch, flywheel, and a spare h23 block sitting in my garage. I've been purchasing at a snail's pace and the oldest part is the turbo at 8 months. Is there anything that I should be concerned about with letting these parts just sit in my garage? Should I periodically put a few drops of oil in the turbo? Is there something I can do for the block to keep it from rusting away?
