323 question

I am looking into buying a 323 gtx and I wanted to find out what common problems there are with these cars. I mostly want to know how much power the awd trans can hold. I am also interested in stock 1/4 mile times as well as anyother info about the car. I found a 88 I believe with the 1.6 turbo in it.
I was also wondering about how much power I can get out of a stock block, and where I can find aftermarket parts for it.

Thank you in advance for your help
