Most likely not your gaskets (there are 4, one for each cylinder), as the proud owner of four '93s over the years I can tell you that I have even reused them several times over and they still never leaked; they are quite good quality gaskets. Also, the turbo/engine pipe joint is quite robust as well.
If you have ruled out the turbo/engine pipe junction, that pretty much narrows it down.
I would guess that you have a cracked exhaust manifold. DO NOT spray ANYTHING on the manifold when the car is running. I mean no offense to the other poster, under normal circumstances this is a sound technique but the 91-94 turbos switched from the copper lock-plated through bolts to hold the turbo on to studs taped into the manifold. These new manifold castings were problematic and brittle, and were extremely prone to cracking under thermal stress. If it isn't cracked now it certainly will be after that.
I would further guess that if you remove the manifold and turn it over there will be one or more large cracks vertically directly behind where the turbo hooks up. YOu might be able to check it with a mechanics mirror and a shoplight without taking it off the car.
I never pass a manifold at the boneyard without checking it, that's how common this is. Nobody sees it much as it is rare to have the manifold out of the car altogether. I honestly have never seen one without cracks; it is only sometimes that they crack through and leak.
I will try to post pictures later, as I am in the middle of a head gasket change and everything is off the car.
I hope I am wrong, and it is your gaskets.
good luck
