Installing bigger injectors

Anyone install larger injectors? I would like to know what is involved and if they are accessible with the motor in?

You need to calculate what your air flow is so as to determine the proper size injector. Depending on the injector chosen, you may have to install larger supply and return fuel lines along with a larger fuel pump. The fuel pressure regulator also needs to be looked at.

And also your MAF. Bigger injectors probably mean a whole new fuel system.

The 996 turbo motor is supported by two bolts... what I have done in the past is loosen these up and they will give you a two inch drop so you can get your hands in there :-)
