If you want to get the turbo manifold off, you really don't need alot of fancy tools, if you're willing to take out the manifold, turbo and dp as one big assembly. I suggest doing it like this, b/c it will be almost impossible to get the back two studs out that hold the turbo and manifold together. I tried it on my 92, and ended up stripping and snapping one. It's ALOT easier if you just remove the turbo, manifold, and dp as one big assembly. Then, once it's out, that gives you all the room and free space you need to work completely around the assembly.
Since you already got the manifold heat shield and IC off, the next step is to remove your alternator. This will allow you ten times more room to work with. Besides, it'll allow the manifold to clear w/o hitting the alternator, easier.
Then, blast some PB on the exhaust manifold stud bolts and the studs where the DP (primary CAT for stock) connects to the MP. Then, CAREFULLY and slowly, start removing the nuts from the exh. manifold studs. You're most likely going to be using a socket wrench with a long extension...so keep it as straight as possible while removing the nuts.
When you get done with that tedious task, remove the nuts holding the DP and MP together.
Then, you'll have two things left to remove...i don't know the exact size, but you're going to need a big ass socket to remove the turbo oil feed line from the block (be careful, there's two metal washers there..don't lose them). Then, d/c the oil return/drain line of the turbo on the oil pan side.
After that, remove the coolant lines on the turbo side, NOT from the radiator side. It's only two small nuts holding this in place on the compressor housing.
After that...slide the exhaust manifold off the studs, and lift up. Careful, it'll be a bit heavy (it's not heavy enough to break your back or anything though =P hehe), and slowly lift it out of the bay (careful not to bang against your radiator core).
And voila! Sorry, i can't tell you the exact tools or socket sizes, but you don't need a bunch of fancy tools this way. And it makes alot of things easier, and actually faster, b/c there's really not much tedious nut, bolt, stud removal. It does sound like a lot, but after once or twice through it (i've done this like 5 times now =T), it'll go quick quick, trust me =)
Goodluck! And if you go this far, you might as well have your manifold resurfaced...it might be a problem down the road. Take this opportunity to replace the HFH too, which you will thank me for =) Also, if you're up to it, replace the oil cooler and oil cooler adapter O rings.
