i have a boosted b16 with an ls trans(it blows), i was considering buying another si, but i hear the gearing is too short, so i was thinking possibly a gsr but people have told me that the input shaft sizes are different? which one should i get and will the gsr bolt right on?

 

i say si trans. i think the gearing is awesome for boost. you dont have much of a top mph, but with the si trans u sure do get there fast.
