Is the Honda Civic 2005 type R the same as the 2005 civic si?

I know they are both ep3 body style. But did America sell the type r? Or is every 2005 civic ep3 here a si? And what's the difference between the ep2 and 3. And how hard is it to get a si with under 75,000 nowadays Thank you.

No. The only type R that ever made it to the US was the Integra Type R. The Si was the highest trim available in the US. I'm not sure what body styles you are referring to with the chassis codes lazy people like to misuse, but if you are wondering about whether it's available as a hatchback or not, probably not. Getting an Si shouldn't be too hard.
