I just recently found that my crankcase was leaking oil instead of my oil pan which I thought the oil was coming from the whole time. I decided that this is a good enough reason for me to swap to an H22 and forget the turbo H23 project for a while until I finish college since I need this car to drive back and forth.
I have a few questions regarding the intake:

1. Are the throttle bodies on the H22 and H23 the same size?
2. Do the AEM CAIs for both engines have the same inside diameter?
3. Will it matter if I use my H23 CAI on my new H22?

A simple yes or no would be good enough. Thanks.

 

They are the same.

If I were you, I would get a 5th Gen AEM intake. It's of a slightly larger diameter than the 4th Gen's.

I had a 5th gen when I had my H23, I have one now that I have an H22.

 

I am using the same intake from my H23 on my H22, So yes, but it is not AEM

That's cool. AEM intakes are cheap these days. When I got mine when I was 15, they cost more than $400. Now you get them for only $50. Hahaha.
