On the unorthodox web site they have full sets of gears and pulleys for the z32 but they only have the crank pulley for the z31 so i was wondering would a set for a z32 be a direct fit for the z31? ,i belive this would work if i bought the full set of pulleys but am not sure.
any input would be great

Im also wondering if the flywheels are the same between the cars.
Fidanza has aluminum flywheels for the z32's for a great price but nothing for the z31's.any input would be great.

 

no and no.

you also aren't looking hard enough. there are plenty of flywheels available for the Z31 if you look.

 

Prices are pretty steep seems like evrythings cheaper for the z32 so if it fits ill take the time to swap it. tanks

 

In my opinion I wouldn't want to loose the dampener on a high horsepower motor with a cast crank.
Forged I wouldn't mind.
I dont believe any one makes an UD pully for the w series motor anyways.

 

well right now im just trying to find a good front pulley(lighter than stock)
and a light weight flywheel so i can have the crank balanced .becuase its better to have the crank balanced with the flywheel and frony pully on to achieve perfect balance.

 

You can have the pully and wheel ballanced independantly.They should come ballanced already.
VGs are internaly ballanced.
However,you will need your crank,pistons,rings,wristpins,rods,caps,nuts and bearings.
