I haven't played with Honda four wheelers in a while. My brother has a 1995 civic CX and he is pretty sure he grenaded the non-VTEC motor. (I don't know, because I live two states away and won't be there to help him swap the motor till later today) He said he found a 1.6L VTEC engine from a 1995si. I am certain the engine will fit, but he is only getting the engine for $300. So my question, does he need the VTEC engine controller as well? He plans to keep his 5sp manual trans, so I assume axles and engine/transmission mounts should be OK. Other answers that will help me search for my own answers... I haven't seen this many acronyms since I was a civilian engineer for the army, I recognize OBD, and ECM, but can you tell me which model of engine my brother grenaded, and which model of engine should be coming from the civic si? When I get to Michigan I will be able to look at casting numbers, but I appreciate a heads up now if you don't mind. It apears, from searching on this forum, that both cars are 5th generation, right? Final request: Based upon the information I have given, which is all I know till about 10 hours from now when I get to MI, if you know of a thread that will help me out here, or if this is a bad swap, I sure would appreciate the answer and/or links pointing me to the information I am looking for.
