I've got 2 complete 91 civic engines. I've used one in an eg before. You just have to use the thermastat housing from your eg so that the coolant temp sensor fits to control the fan relay. I'll deliver for extra money but I'm trying to get $250 for the one out of my mom's automatic 91 civic or $200 for mine out of a 5 speed 91 civic. I don't know the milage for either but the 5 speed one has been sitting for over a year. I still have the auto one in the car and can start it for you to see before you buy it. There is no smoke. Either should run good. Interested in either engine, call or txt me, Stephen, at 434 409 6637.
