I agree with omniscient but if you just want a descent swap. Get either a B16A generation 2 which runs 170 hp or the gsr engine which is the b18C1 which runs 180 hp. The price difference between those two engines is about $1,000. A good decent B16A complete swap with LSD is about $2000 - $2,200 and this is the engine used on the SiR in Japan. A gsr good GSR engine will cost anywhere between $2,800 and $3,400. I would say go with the B16A.
