it shud be ok but you will need shorter belts and it will be turning the other pullys at a fiffrent speed to standered (slower i think off top my head anyone with knolage of superchargers will no)

also id do this for looks and maintance

The pullys P/S and alt will be turning slower

[Bobbys14]

Will it be possibly to slow and not charge my battery and to slow to work the power steerin.?

[moons657]

id say its smaller to stop the water pump working too fast when revving real high,although yashio factory do a water pump pulley that stops this?
what advantages did it say on the website ya bought it off??
