theres a LOT of choices..need budget/power goals first..
if it were me..id get some eagle rods and high comp pistons ~11.5:1 and rebuild the bottom end..or figure out an oem piston setup to bump up compression..

OR you could start building your head now..do valvetrain and get a nice set of cams..

Or you could get all your fuel done for whatever hp u expect to push and get ur car converted to obd1 so you can get a good tune when u do decide to upgrade other things..
