My 4dr Civic lx D15B7 engine is tired at 220k, seems to be losing oil / smokin' a small amount. regardless, not interested in fixing it, rather just swap something else in. I'm not looking to buy tires every month with a 250hp motor, I just want something else with a little more power than 103 hp. Found a guy selling a D16z6 Vtec, he's asking 300, but I could probably talk him down. From what I'm hearing on these forums, most of the time these motors either bolt right in, or you have to use a combonation of motors mounts from donor and stock motor mounts. Also, this new engine is VTEC so i would have to grab a new ECU, and wire that in...somehow. also i've worked on cars for 15 years.
