So I'm working on a all motor B16 block / B18 head CRX. My transmission grinds and I hate the gearing in it You can do 105 in 3rd, that's just dumb. The stamp on it says YS1 which from the reference section has shitty gearing for all motor and pretty much any motor that doesn't make crazy amounts of power. Anyway, I have a choice between a SiR I tranny and a '94-95 GSR tranny. Which one is better for my application? Thanks in advance.
