hello to all, I am new to this forum and was just wondering what my options are if i wanted to do an engine swap in a '05 civic lx 4dr, I've seen alot of info on k20a,k20a2,k20a3 swaps but was wondering if there was any other engines available that would provide decent power gains versus the stock d series if i would like to get good power with an all motor set up. i would also still require the car to be street legal and reliable. any information wold be much appreciated as i am not very knowledgeable when it comes to honda engines as i am well learned in rotary engines.
