I need to know if there are any differences in the blocks, my block needs re sleeved and I have found a 6 block for cheap so will it work?

 

[cadhun02]

yes the blocks are the same the heads change though with years and with emissions if you have a cali emissions head or a can/fed emissions.

The mazda6 block lacks a upper left boss near the water pump for the the alternator.

Meaning when you use a "6" block you only have three bolts to hold on the "3" alternator.

 

[cadhun02]

yep. I believe you are right.

 

[MZR23MZ3]

im trying to remember how the alt was.... can you get by with only using 3 bolts

 

[MZR23MZ3]

???

 

[cadhun02]

oh yeah three will be good.

 

[chillin in the milan]

you could use a fusion alternater, they use 3 bolts

if the mz3 one doesnt work ill just put a 6 on it!
