fellas i'm looking for the alternator & power steering belts for a 20b.....could i get them from mazdacomp?? i have the mazda part #'s
alternator is NF01-18-381 and the Powersteering is NF01-15-909....could the 13brew belts work???its not for me,its for a friend in another country....thanks

 

Are these for Rana (aka spanner)? He was looking for something like that. Mazdacomp can get them and Corksport can get them.

 

you have the part numbers order them from mazda!
they can get them...

if you think mazda is to much money then go to
a auto parts store and start trying different sizes until
you find the one that work

The 20B pulley belt is a "7PK" where the 13B one is a "5PK".

The 20B alternator has a higher capacity than any other.

100Amps from memory.

 

dude actually its not for Rana,its for my friend Cris.....Rana will get his 20b next year, after his house is finish building.....thanks for the info,i'll call corksport

 

Is the amp rating for the RE (2 rotor) alternator the same as the 20B's alternator? Anyone know?

 

From memory........

20B alternator = 100A
13B alternator = 085A

 

FD3S altenator = 100A

 

just put a string around the pulley's and measure the length. I ended up using 13bt pulley's for this reason. Just take the measurements to autozone or something and get the closest thing you can find... I haven't ever seen a problem with this approach.

 

the stock belt is wider and short, like sumo

nonetheless, this worked for me.

 

like sumo?

 

Are you sure? I was bored today so decided I was going to switch out the 13b alternator in my Fd with my 20b alternator because I heard that the 20b one had more amps. Well I just looked at the serial plates of my 13b alternator and it's rated at 12v and 100 amps. I was shocked because my 20b alternators serial plate shows to have a rating of 12v and 90 amps.

Whats the dea?l I thought the 20b alternator was suppose to be more powerfull?
