I just bought a 87 with 107,400 miles on it. Its not turboed but has full GReddy exhaust and intake. What other common mods are done to these cars?

Maintenance.

 

Agreed. Before you do anything, remember that you just bought a 23 year old car with over 100K miles on it. Change all the fluids, filters, spark plugs, etc. Give the car a thorough once over to see what may be in need of replacing. Worry about it performing perfectly in stock form before you worry about mods. Unless of course, something you plan on upgrading is already in need of replacement.

 

plus won to that.

 

Check all your bushings and mounts. The engine mounts in particular like to break.
