a type r has too high of compression for turbo but it has been done. i owned a 98 gsr and that was a blast to drive. get a gsr and turbo that later on. gs and ls had a b18a and b18 b motors i believe, the gsr has b18c and the type r is b18c5 . a and b dont have vtec, and you WILL want that so spring for the gsr, lower compression, vtec and go to teamintegra.net and educate yourself it is an awesome website
