I just got a 2003 Si last Saturday. I am looking in to building/swapping the engine. From what I have read thus far an engine from an integra type s or type r is the way to go, but I know that I am going to want to build and turbo that after I get it. This car is a daily driver, but the stock engine is not a lot of fun. The i-vtec kicks in at RPM's way too low and it currently redlines at about 6600-6800 RPM. Do you guys have any suggestions?

 

just do a rsx type s swap
