Ok....I have a 94 4cyl. 5 speed 4x4....I want to put that motor in a 94 that also had a 4 cyl and 4x4 but it is an automatic. Am I gonna have a ton of problems or what will I need to change such as Intake, throttle body, etc.? I Have to remove both engines and put the good one from my truck (rotted out) into the new one that is mint....I want to post pics of the whole project as I go....Am I going about this correctly?
P.S. I'm not a pro mechanic but I've done my share of rebuilds and engine/tranny changes in vehicles so I'm pretty knowledgeable as far as if you tell me the problem I can fix it but I'm a little light on troubleshooting and I don't work on things as much anymore due to work.
