Removing and Replacing Turbo...one bolt!

[Derek Pulvino]

I asked a while ago if anybody had hints for removing and replacing  
the turbo and was told there is one bolt that's difficult.  Well I've  
dug in and I'm now down to one bolt.  It's the bolt located, as  
viewed facing the engine from the passenger side, on the upper left  
hand side of the flange attaching the turbo to the exhaust manifold.   
Was able to get a 15mm open end wrench on it but couldn't get enough  
force to budge the bolt...and I think the bolt is situated in a  
manner that has the outside of the wrench hitting against the  
surrounding flange when I try to turn it.  I'm taking a quick  
breather to think on this, but in the meantime, any tool  
recommendations to get at this thing?  Couldn't get a socket or the  
closed end of an end wrench on the bolt.

Oh, and once I get all the bolts off I think I'm going to have hard  
time removing the turbo.  I've got studs that coming out of turbo  
into the downpipe, and from the manifold into the turbo.  Seems like  
that's going to make removal a touch dicey given the 90-degree offset  
on which these bolts protrude at.  Thoughts on this?
