Hi new to the site, made strictly to get an opinion from an expert on honda/civics. I have a 1995 Honda Civic DX Coupe with the 1.5 D15B7 motor. The previous owner seems to have blown the bottom end and has replaced it with a bottom end from a 1990 Honda Civic (Engine is a 1.6L D16A6 Or a PM9-5). It's one of those two enging numbers, cars not on my property at the moment to check which one. I need to know if and what complications this poses, and what I need to convert or adjust to the original 1.5 top end of the motor. I already know the timing is a tad different and it uses a belt with 107 cogs instead of the original 106. Are there any other things I should know about? Can someone let me know on any major timing complications? Anything of the like that I'd need to know. Thank you for your help. You can also email me at juggyj454@yahoo.com.
