I have a 1993 accord EX with a blown motor code a-3 and a wrecked 1991 accord lx code a-1 could i put the a-1 motor in the ex accord? and if so will anything have to be changed?

 

It will be more of a hassle to complete this task than to just buy a used engine...

My advice is to buy a used engine 92-95 OBD1, Your 91 is OBD0....You might be able to swap all parts inbetween which is why it is a hassle

 

What are the big differences form an ob0 engine and an abd1 engine because i have 2 cars that i am trying to make into 1 and not spend that much money if i can. Just going to be a work car and if i can get these motors swaped will i just run inot a bunch of problems. And is there any way to do it without the problems like swaping blocks?

 

Swap ECU
Swap wiring harness
Might be it

 

I have a h22 that I am planing on putting in a 91, 4dr acura. Is it a good idea to use a f22 gear box in this set up, or just use a h22 gear box also and what ECU would I get the most out of.
