Tightening Manifold Nuts (SR20DET)

[SolaraOnBronze]

Alright, this may seem like a stupid thing to make a thread about, but a quick answer would be appreciated. My manifold to turbo nuts have come loose recently, causing the exhaust system to leak. I have a new turbo setup that I plan to install this winter, most likely with a new manifold, so I would prefer to just tighten them up for the rest of the summer/fall. I have been able to tighten three of the nuts with everything on the car, but there is one that I am not able to get to. Here is an illustration of the nut I am referring to:



I have read in a few threads that it is possible to tighten/loosen all of these with the turbo on the car. I am able to use a combo of wrenches, ratchet wrenches, sockets, and extensions to tighten the other three, but I am having trouble gaining access to this back nut. Does anyone have any advice for me as far as specific tools or techniques? Any info is greatly appreciated, thanks!
