Alternator Pulleys?

[Civvy]

Does anyone know if the pulleys are intechangable on the A20 alt ('v' belt) to the B20 Alt (flatter belt)?

Cheers!

No theyre not! ...civvy! Turns out i had to get the new pulley into the shop and have it redrilled to fit the old Alt. Managed to pack the old alternator out on the B20 brackets to alighn it true with the crankshaft pulley therefore the newer B20 multigroved fanbelt fits!

Alternator job done!

Doesn't your A20 alternator look like this?:



With a flat belt like this?:

[Civvy]

yes and no! That is the B20 alternator! (with integral fan + regulator + flat belt) mine is the A20 Alternator (external fan without regulator + 'v' belt) I have swaped in a B20 engine, but, my car had the A20 carbed engine and i couldn't use the B20 Alternator because of the built in regulator! Hence me wanting to change the puleys!
