Hi.... my S15 6 speed gearbox seems having some weird sound. Juz wanna ask whether can RB25 gearbox fit into S15? Coz i heard that RB25 gearbox is stronger compare to S14 5-speed.

Correct me if i'm wrong:hurl:

Yes it is stronger than the S14 but you have to make modifications to fit the S15 bell housing, drive shaft and change the diff as the ratios will make the gearing to tall. you need at lest a 4.1 diff centre.

The Z32 gear box is also another strong option
