junkyardin..what engine?

so i'm goin to the junkyard this weekend...i guess they have a nice setup...all the cars are off the ground and its all gravel.......well someone said that most engines are $100 pull it yourself......i thought of looking for a 93-97 delsol and a 99-00 civic SI to get a b16a2 but is there anything else i should keep an eye out for? like what year car and what series engine?

i'm hoping to find an integra GSR or USDM type R hangin out with the engine intact.......

plus i'm hoping to find civic SI wheels...if everything goes right i might atleast get a set of rims and my new interior pieces and maybe even seats
