does any one know if a crank pully from any other b series engine will fit the crank of the b20a. i can get a brand new oem honda single belt pully. it is a factory option for the bseries. there is only one groved section just to power the alternator. it only weighs 1.8 pounds compared to the stock 7-8 pounder.

try it, and at worse, you can hawk it off to some kid w/ a civic.

yes you can but you need to put a 1/8 spacer for it wont hit the timing belt cover.here of my b20a with a crank pully from a 94 integra

Why not just find a good machine shop and get them to turn one up out of alloy. Would weigh 5/8 of fuck all that way.
Mite cost a few $ but could be worth it.
But since all the weight of the oem pully is all fairly close to the crank centre line, You prob wouldnt feel any difference apart from maybe on a dyno.
You would be better spending the money on a light weight flywheel which would make quite a noticable difference in the way the engine picks up revs.

1/8 thick? sweet. and btw, that is a very clean engine. i already have the aluminum flywheel.
