if its quite alot smaller, then its probally the wrong one as the belts just gonan come off i would i thought

I would only ever fit a stock OEM Toyota harmonic balancer/crank pulley. Have a read here of it's function http://www.mkivsupra.net/vbb/showthread.php?t=35945

"underdrive" pulley?

(I wouldn't take all of that article as gospel, but it does accurately describe an underdrive pulley)

Which pulley did you get for it? Some of them are ok to use.

The ATL (Titan) and boostlogic ones look smaller because they dont have the large back plate on them but the surface the belt sits on is the same diameter as stock and they have the balancer.

 

Tell us which one you have or post a pic and we can let you know.
