background info: hey, i have two 1990 civics. one is a 4 door sedan, LX, with an auto tranny and the other is a DX hatchback with an auto tranny. my DX head is cracked but the tranny is good. my LX engine is good but the tranny is bad. questions: 1.) can i simply swap the LX motor into my HB? 2.)all i need to do is swap the engines right? or are there other things, i.e ECU... etc? thanks for the help.
