i currently have a 1991 with a b18a1 inside and want to build it but ive found a b18b1 built already and never put in a car yet…the problem is its out of a 95 teg and its a b18b1. ive been told that its a straight drop out. but i need to kno for sure bc i want it now and i don’t want any problems. does anybody know if its a straight drop or not?

yes, the b18b drops right in. you will need to transfer some of the sensors and stuff from you b18a, but it shouldn’t be a problem. the two motors are almost identical anyway.
