Crankshaft pulley..

Hello there,
I need to change my crankshaft pulley, so i have a question here:
Does 4A-GE crankshaft pulley differs from 4A-FE or 3S-GE crankshtaft pulley?

As far as I know the OEM 4AGE AE86 RWD crank pulley is unique. The
AE86 has two x 5-groove belts, and the outer pulley is about 10 mm
smaller in diameter.

FWD 4AGE engines have both pulleys the same size, but they will fit on
the RWD crank. You will need to adjust the alignment of the pulleys by
machining a millimetre or two off the boss, as the FWD crank pulley sits
a bit further from the engine.

AW11 (early MR2) 4AGE engines have stepped pulleys, but again they
have different offsets from the AE86 pulleys. They will fit with a bit of
adjustment. The belt alignment will not be perfect, but should be close
enough if you are running two belts.

Of course, if you are only running one belt, you will be able to get the
alignment perfect with some adjustment of the hub. AND, don't forget
to get your torque wrench and tighten the bolt to 137 Nm. If you don't
get it good and tight, it will loosen off, and you will ruin your pulley,
or even the end of your crankshaft
