OK first, so is the 05 bell swapped on too a r151f transmission to fit behind a 3rz just that straight forward? Since I can't find marlins bell kicking about. Now second, the ra60 6spd is a typical r series trans. Ie use my r151f bell on it ot for a 22r motor. Looking to beef up to a r trans for a 2wd with a 22/20r motor. Plan was to just buy a r155 from a 05 2wd and have have what I need but a 6spd might be fun. Were the issues with the 6spd from over powering?
