i did..tons of it too...its just that no one really recomends what crank to use...im just taking a guess here but it seems like most ppl stick with the stock b20 crank...and get internals for the b20....because the piston would stick out if i get gsr rods and pistons and all that right???? correct me if im wrong....so anyways.. i guess my question is...gsr crank?? or b20 crank??? ....
