OK the main reason I dont want to go b16a is because of the trans. I know nothing about them and in the city I live in they are way over priced. I am very happy with my si's trans. so what I am asking is what b-series trans is equal to my si.
actually depending on which b16 trans you get will depend on the gear ratios. but all of them have a better final drive than your si's i believe your si is a 4.2 finaldrive whereas the b16 cable is 4.40
