Question 930 Compression test Question

I am new to this forum and have an '89 930 I'm working on. I want to do a compression / leak down test on it. Can this be done without dropping the motor? If so, what needs to be removed to get to the plugs? Also, How do I check the turbo unit to make sure the it is working properly and in good shape?
