The drivetrain conversion is very possible. And dropping a 4g63 in place of the 4g64 (stock spyder GS) would be cake. Don't know why you wouldn't go with the 4g64 bottom end though, giving you 2.4L instead of just 2.0L. All in all though, it's obvious some of you guys are clueless...sad being most of you actually own a dsm.
