Hi, Welcome to HS
I think a great enginge to drop in would be the 2002 RSX's 200 Hp engine... sorry i don't know all the niffty engine codes.... I dont' even know if it'll fit or how to do it...
Another pretty good site for you to check out is
www.2k1civic.com I really like a lot of the DIY thread and How To threads, and parts section, But the Forums there are a little lacking .. .
Happy Honda'ing
