i have a 1991 integra ls. i need a motor so taday i found one but the car is newer than mine. am not sure what year it is all i know is that it has the circle light in the front and that the moter is a dohc non vtec. will that motor drop right in?

 

A B series is a B series, yes.

 

The motor will drop in, but depending on the year you might have to redue the wiring harness. You car is an OBD1(or 0?) and the new engine COULD be an OBD2. anycar 96+ is OBD 2
