Aight...this thread might make me sound ignorant but the only way to end being ingnorant is to figure shit out. I have a 1990 teg ls that I'm trying to do a motor swap on...I know a B18a1 and a B16a1 will fit into it...but everyone posts they have a b18 or a b16 in like a 94 teg. would that same motor fit into my 90? I'm in need of some serious help...I'm tryn to swap this motor and get rid of this car. Someone help a noob out!

 

b18/ b16 are the same as a b18a1/b16a1. And yes a b18 out of a 94 integra will drop into a 90 integra. I have a 97 b-series motor in my 90 integra.

 

dude seriously you have no idea how much uve helped me...thanks
