newbie need help on rebuild!!!
 

i need a mazda 13Bt rebuild kit for an 89. ive been looking on other sites and what does a full master kit come with b/c i want to replace and totally clean up my engine? also what is the difference between a 2mm and 3mm seals. what difference does this make. Im new to rebuilding these angines so any tips and pointers on what to get would be handy! thanks

A full rebuild usually means it comes with apex seals and springs, rotor bearings and other "hard" seals. 3mm seals are obviously larger for durability and higher boost, but your rotors need to be milled to accept the seal. Your new to the rotory? Get a second job. Good luck.
