I think you can do this. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/huh.gif" border="0" valign="absmiddle" alt=':huh:'></td></tr></table><span id='postcolor'>
The RB20 stroker kit makes it about 2.2-2.4L depending on what combo you use... check out this page for more info

As far as RB20 vs RB25 the RB20 has the advantage of a lower compression from the get go... allowing more boost without changing internals (less expensive). Both of these motors have ceramic turbos which is going to only allow 1 bar of boost safely. The RB25 has the advantage of a better flowing head... more hp down the road. I don't think it's unheard of to swap the head on a RB20 for the RB25 head... but it's probably like an LS VTEC motor where tweeks are required to make it work. I hope this helps you in your decision my friend... good luck with what you chose to do.
Also... don't forget wiring. Putting an RB into a S13-15 is going to require some thinking when it comes to wiring. There is a brain for the auto seatbelts that is connected to the main ecu. Here's my dollar fifty on the subject
