injectors are hard to tell, unless they are green, then you know they were changed. if its got anything smaller then a 3.4 pulley on there it should have been upgraded to 42's at min.

you're gonna want to get a way to scan this set up. you also might want to get a wide band if it dont have one. im sure its been tuned or it would not run so well really.

big thing to be scanning for is KR, knock retard. that will chip your pistons and kill your fun. nice to know if you have any.
