there were 2 type r motors:

b18c5 Integra Type R
b16b Civic Type R

The Civic Type R wasnt avail USDM (I dont believe) but the Integra Type R was a tuned down version. I have that engine block dropped in my car with a GSR head. The compression is a bit higher than the average b18 because of that. It's bucks basically but there are no Eclipse Type R's or any of that shit. They're just shithead ricers.
