Hey everyone... sorry if this is a repost... but i have been looking for a while to find an answer to my question and havent found it... My 2004 civic ex coupe needs power... i know that modifying the stock engine is out of the question (waste of time and money)... however, i can not decide on an engine to swap. I've read a lot about the K20a3 and a2... even though the a3 is looking more promising because of the 5 speed trans. i understand there are better advantages for the a2. For my price range and power desires, i am looking at the a3. i am still unclear about the whole engine swap... i know it's not as easy as in and out... other parts are needed to make the swap complete... Has anyone out there done (or know of someone) who has done a swap in my generation of honda's? If so, what other parts did they have to purchase or what modifications did they have to make to stock parts to make them fit with the swap. (ex. tranny?, ECU?, mounting bracket?, etc) Right now i only want to do an engine swap to get a little more power and leave potential for additional upgrades... (maybe a turbo). Your help is greatly appreciated!!
