the H23 is great. The H23 would be the ideal engine to go with if your planning on adding a turbo. i think the H23 runs about 2000 used and the H22 runs about 2700 used depending on where you get it from. in a light civic the H22 or H23 would definatley get you where you wanna be. high 14's. and with a few modifications you'l be in the low to mid 14 range. thats just my estimates tho. the swap is ridiculously expensive but it is somehwat costly. i say go for the H23.
