Your results may vary. Side effects include bankruptcy, loss of girlfriend/wife/kids/parents' affection, chronic knuckle cuts and bruises....
When the timing chain snaps, it's usually because the balance shaft sprocket on the crankshaft has packed it in. The balance shaft chain falls down and tangles with the timing chain, and presto! you're parked.
You should be looking for the following devastation:
* Aforementioned sprocket will be shredded but good.
* During the destructo phase, the grenaded chains will have eaten away at the timing cover, often opening invisible (but effective) holes into the oil pickup tube. You'd be well advised to replace the timing cover if it's been chewed up, because you risk low or no oil pressure if you don't. Hard to find the part, and not cheap, probably $150 or so.
* Valves? Bent. Replace head, don't rebuild. You'll save money in the end this way. Turbo/non turbo heads are interchangeable, and in a pinch you can use a head from an older 2.0.
* Pistons? Not broken, but quite possibly to probably dented and/or embedded with chunks of broken valve guide from the head. You MAY need to replace one or more pistons.
* Cylinder bores -- may be seriously scored from any valve guide bits flying around in the final moment. No guarantee you'll find this; if you do, consider the block done, unless you're willing to spring for a rebore/hone and a set of oversized pistons, rings, etc. Major bucks.
* Oil pan -- clean this out! There will be plenty of metal shavings and pieces of chain drive down there.
Add to all this the usual rebuild stuff, like head gasket kit, spark plugs, the proper Loctite 518 or direct substitute (you MUST use an anaerobic sealer -- it must be 518 or something specifically formulated to mimic 518, or you'll have oil leaks), time, psychological care, etc.
Could be a fun project but be ready to declare the engine dead if you see block damage and/or piston damage. Hard to find 91-93 2.3 turbo motors these days, and whichever one you find is going to be susceptible to the same balance chain sprocket weakness. This is owing to the sprocket's soft metal, which was remedied beginning in 1994.
If you decide to proceed, we're all here ready to help you through it.
When you say the price is right, I assume you're saying it's between $0.00 and $500.00. More than that, keep looking for another car.
