Ok I did my searching (I have been apart of this forum a long time so dont tell me to search) and I havent come across any info on how the SR20 goes into the B13. There are alot of B13s around here for sale but I cant find an SE-R under 3 grand. So I wanna get a classic Sentra and put in an SR20 but I dont know what im getting myself into since I only know alot about the B12. Im just getting sick and tired of these civics around here who think they are badass and think they are the fastest cars that rolled in Columbia SC. Help me out so I can put these lil school girls to shame!!!
