All 1gs are OBDI and all 2gs are OBDII. They actually started mass production with the OBDII port in 1996. The main difference between 6 bolt and 7 bolt motors is that 7bolts in 2gs are known to "crankwalk" (search that term) and 6 bolt motors generally do not. Even though there have been cases where 6bolts do crankwalk its very uncommon. When people say 6 or 7 bolt they are referring to the number of bolts on the flywheel. 90-92.5 came with a 6 bolt and anything later than that had a 7bolt. Although 1g 7bolts are less prone to crankwalk. Its highly recommended to get a 6/4 combo. There are things from different years people tend to like such as the 90' external oil cooler, there is tons of research you can do. The things you can do are: Check for strut rust, make sure that maintenence has been kept up to date, see if the car makes any wierd noises, shifts smooth, check for any leaks underneath the car, shaft play in the turbo, there are countless other things to check for I just tried to point out some big ones.
