Anybody know where I can get them?

 

I don't know of anyone or place to get a specific 20B rebuild kit. But you could buy 2 cosmo 13B-RE or 13B-REW kits and that should work cause most rebuild kits are mostly seals and the 20B is just an extra rotor on a 13B-RE. I think most of the seals are the same since they are built exactly to the same specs.

But I am not 100% on this so don't flame me.

 

Thanks but 2 13B rebuild kits is pretty expensive. Anyone else have an idea?

 

how about....off to the 20b SECTION.

 

There must be someone here with a contact to japan
that could go to a mazda dealer in japan and get the
part number for the gasket set... once you have the number
you can go to a dealer here and order the part.

No need for a 20b kit. Just pick up 2 86 NA kits from mazdacomp. Its cheaper than the 20b kit and you'll have extra parts left over to scatter about aimlessly. For the exhaust gasket, cut the second NA exhaust gasket in half and put it on the front rotor, use the remaining NA exhaust gasket on the 2 rear rotors.

Extra things you may need, primary injector seals, tension bolts and seals, TB gasket and outside O-ring, upper and lower intake manifold.... it still comes out cheaper than the 20b kit... I got everything to rebuild my motor from mazdacomp, including all apex seals, side seals springs, blah blah blah for < $1200

 

mazdacomp does stock 20b rebuild kits. the part numbers for the intake gaskets are NF01-13-111A and NF01-13-112A for the upper
