D16Y7 to D15B7 Swap
 

I have a 96 1.6L Civic EX manual with a blown head gasket. The guy said he drove on it for 9 months so the motor is junk. I also have a 95 1.5L Civic LX or DX with a good motor, bad body. How do I convert the 95 obd1 motor to obd2. I know the transmissions are compatible since they are both b series motors. Please help and what else do I need to know.
