well.. from what ive heard, the b16 is better for all motor set-ups coz itll redline quicker.. but the gsr would be a better choice for boosting or daily driving on the freeways.. i went with the b16 tranny on my b20vtec and it didnt make too much of a difference on the track for me, but i hate it on the freeway... 80-90mph cruising on the freeway hittin vtec kills my mpg..
