Get the v6 (LS) with a 5-speed. Avoid the 4cyl automatic (like mine. ). Also, the OBD I v6's have a little more horsepower than the OBD II's. Not really enough to matter though.
Yeah, the mx6 is very mod-able. Check out the 2nd gen performance section for more information. Also, if you have any more questions about modding your six, first try the search box at the top-right of the page. Most questions have already been answered at least once on this site, so you'll more likely find what you're looking for that way. If you've searched and still need more info, feel free to ask any of us in the appropriate forum for your question. Hope this helps!
