Can you convert a 2008 Si to a type R?

I heard you can import a type r to the US but you'd have to pay for registration and some other stuff. Is that true?

And I don't know how to drive standard yet so, When do you change gears? Is it when it gets to 4000 - 5000 Rpm or 7000 - 8000 RpmCan you convert a 2008 Si to a type R?
there is no 2008 type r and well yes u can import a type r but id cost a lot because the shipping is crazy and actually u cant register the car since it doesn't actually pass us crash test ratings and as for the shifting if you were racing yeah bout 8000 for a b18 type r engine but under normal driving more like 3500 id actually be cheaper to buy a civic hatch back or a integra and for you to swap out jdm parts
