Hi all , I have a 1997 4 door civic LX. I have little automotive mechanical experience, just about all I've done is change the oil. My friend says he has access to all the tools available to perform an engine swap( he can borrow some from his work) and he has done them with his car. I tend to notice that the peoples projects ive found using the search feature on this forum arent 4 door cars, is mine suitable?. Haha i even found this quote QUOTE(pissedoffsol @ Oct 16 2002, 12:14 AM) lx = 4 door garbage Anyway, in the engine swap 101 thread these were listed as the engines that would fit my car: 1. B18C1: Completely bolt-in swap, VTEC needs to be wired. 2. B16A2: Completely bolt in swap, VTEC needs to be wired. 3. B16A3: Completely bolt-in swap, VTEC needs to be wired, OBD Conversion. 4. B18C5: Completely bolt-in swap, VTEC needs to be wired. 5. B18B1: Completely bolt-in swap. 6. B16B: Completely bolt-in swap, VTEC needs to be wired. 7. H22A: Mount kit required, Hasport shift linkage, VTEC needs to be wired. 8. D16Z6: Completely bolt-in, OBD conversion, VTEC needs to be wired. 9. D16Y8: Completely bolt-in, VTEC needs to be wired. but does that include the 4 door model as well, i dont know if the engine bay sizes are differnet but i know there are some exhaust length issues. If those engines fit my car, out of which would you probably guide me towards. I am thinking the B16A2/3 because of the price range. Also will a new powerful engine negatively affect parts of my car, such as putting extra wear on parts that were not designed for a car with this type of engine?
