Found a b20 swap for good price the crank pulley is gone and cannot find good information on whether using a ls pulley would be okay. What worries me is the smaller size compared to the b20 crank pulley and are all the b series crank pulley timing marks the same. just trying to think of any problems before iI run into them.

Any input?

LS is fine. Just make sure it is indeed off of an LS or you're gonna have a hard time finding replacement accessory belts.

thank you just for future reference on all the b series b16 b18 b20 are the crank timing marks the same? I know of the methods for finding top dead center but was curious anyway?

You should be able to use the LS pulley, just use LS accessory belts.

The last time I put a b16 crank pulley on a b20 the marks did line up. But like I said if you put a different pulley on there it will make it hard to find the correct accessory belt.

On the aternator im pretty sure you can just use the pulley of the corresponding alternator ls pulley ls alternator pulley etc idk about power steering and ac though. custom belts easy to find at napa anyway
