I'm considering on trading someone for my swap that I have which is a h22a motor for a crx si. What I need to know is what kind of things should I look for before buying/swapping. I'm suppose to pick up the car this coming sunday. I used to own a 91 Honda Crx si and the car was great I love those little cars.

What is the number on the si block?

Any defects or anything I should look out for? Thanks guys for looking and helping with advice in advance.
