Hi, folks! My son and I have a 91' Honda accord ex and want to fix it up. My son is sixteen and he's taking a course in school called I car. So he asked if we could rebuild the ex just to see if we could really make it nice. Now the ex is a real eye sore, but it has been running for over 20 yrs. We have about 350 thousand miles on engine which I am about to take out and rebuild but I just got a h23 engine that I want to put in because we can't aford to have the car down for long. So the plan is to swap the engine's so he can take it to school and rebuild that one first then get the body work ( ya know honda wheel well rust ) done and prep for a paint job. So is there a lot to this engine swaping f22 to h23 non vtech?
