Hello. I expose my question. I have a Nissan Primera p11 sr20 DE engine and I would like to put a gearbox with a shorter ratio. Does anyone know what gearbox I could adapt or put? A greeting and thanks in advance.

you want a rs5f32v gearbox from a vzr or autech (4.4) or an Mfactory 4.7 or 5.1 crown wheel and pinion to suit your gearbox
A shorter (numerically higher) final reduction multiplies torque and lowers the top speed in every gear that isn't an overdrive. It still multiplies torque in the overdrive but usually doesn't change top speed much. Overall reduction is final x transmission ratio.
